detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings in order to make the present invention more clearly understood by those skilled in the art. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

This embodiment provides a method for loading a picture resource. As shown in FIG. 1 , the method includes:

Step S101, the loader of the picture background setting and the loader of the picture content display are encapsulated into the picture resource loading class.

In this step, the picture resource generally includes a picture background setting and a picture content display. When loading the picture resource, the background setting and the picture content display need to be loaded, so the loading program of the picture background setting and the loading program of the picture content display are performed. Encapsulated into the image resource loading class Decode DrawableHelper, convenient for unified loading management.

After the loader of the image background setting and the loader of the image content display are packaged into the image resource loading class Decode DrawableHelper, a bitmap set mLeakBitmaps is also needed to store the bitmap pixel data Bitmap generated during the loading process in advance. The bitmap set is in mLeakBitmaps.

Here, the loader of the image background setting and the loader of the image content display are encapsulated into a picture resource loading class. The implementation of Decode DrawableHelper is as follows:

DecodeDrawableHelper.loadBackground

DecodeDrawableHelper.loadImage

The Background refers to the background of the picture, and the Image refers to the display of the picture content.

Specifically, when the picture resource is loaded as the loading of the picture background setting, referring to FIG. 2, the loading method corresponding to the DecodeDrawableHelper.loadBackground is:

Step S201: Receive a resource, and determine, according to the resource ID, whether the resource type is a picture resource.

Here, the different resource types correspond to different resource IDs. When the resource is determined to be the background resource of the image according to the resource ID, step S202 is performed. When the resource is determined to be the color value resource and the XML resource, step S203 is performed. The resource type includes a picture resource, a color value resource, and an XML resource. The picture resource may include: a normal picture and a point nine picture; and the color value resource includes a color value type such as RGB8, RGB4, and the like.

In step S202, it is determined whether the background of the picture is loaded. When it is determined that the background of the picture is not loaded, step S204 is performed. When the background of the picture has been loaded, step S205 is performed.

Step S203: When it is determined that the resource is a color value resource and an XML resource, generate a corresponding bitmap object according to the color value resource and the resource ID corresponding to the XML; and assign the corresponding bitmap object to the view that needs to display the background.

Specifically, the corresponding bitmap object Drawable is obtained by the Resources.getDrawable(resId) method, and the bitmap object Drawable is assigned to the view View, so that the view View can display the corresponding resource. Wherein, the resId represents a resource ID.

Here, before the bitmap object Drawable is assigned to the view View, the method further includes:

Determine whether the SDK_INT in the system is greater than 16. When it is determined that the SDK_INT is greater than or equal to 16, the View calls the setBackground(drawable) method to obtain the bitmap object Drawable, and uses the bitmap object Drawable to assign a background, thereby displaying the corresponding resource; When SDK_INT is less than 16, View calls the setBackgroundDrawable(drawable) method to get the bitmap object Drawable, and uses the bitmap object Drawable to assign the background to display the corresponding resources. It should be noted that the background referred to herein refers to the display background of the display color value resource and the XML resource, which is different from the background image.

Step S204, obtaining a view view size and a size of the background of the image to be displayed, determining whether the background of the picture needs to be compressed according to the view size; when the picture background needs to be compressed, performing step 206; when the picture background does not need When compressing, step 207 is performed.

Here, the size of the background of the image is obtained in this step in order to reduce the memory occupation. The specific implementation manner is: setting whether to obtain only the boundary inJustDecodeBounds value is true, when set to true, in the process of loading the background of the image, only Get the length, width, and height of the background of the image without actually parsing the background of the image. After reading the size of the background of the image, set the value of inJustDecodeBounds to false.

Step S205, when it is determined that the background of the picture has been loaded, the first bitmap pixel data Bitmap of the background of the picture is called from the bitmap set mLeakBitmaps. In order to reduce the occupied memory of the first bitmap pixel data Bitmap, in the embodiment, one pixel in the first bitmap pixel data Bitmap is set to occupy 2 bytes, for example, The loading format of the first bitmap pixel data Bitmap can be set to Bitmap.Config.RGB_565, and the Bitmap.Config.RGB_565 occupies 2 bytes.

Step S206, compressing the background of the picture according to the first compression ratio, and compressing the background of the picture, and generating a first bitmap pixel data Bitmap of the background of the picture according to the background of the compressed picture; wherein the first compression ratio is based on The background size and view size of the image are calculated.

Step S207, generating a first bitmap pixel data Bitmap of the background of the picture according to the current picture background.

Step S208, after the first bitmap pixel data Bitmap of the background of the picture is generated, buffering the first bitmap pixel data Bitmap into the bitmap set mLeakBitmaps, and determining whether the background of the picture is a point nine map, such as determining When the picture background is a normal picture, step S209 is performed; if the picture is determined to be a point nine picture, step S210 is performed.

Step S209, when it is determined that the background of the picture is a normal picture, generating a first bitmap object Drawable according to the first bitmap pixel data; assigning the first bitmap object Drawable to a view View that needs to display a background of the picture, So that the view View can display the background of the picture.

Step S210, when it is determined that the background of the picture is a point nine map, deleting the generated first bitmap pixel data Bitmap; searching and parsing the picture background resource by using the resource ID to generate a second bitmap object Drawable; The binary bitmap object Drawable is assigned to the view View that needs to display the background of the image. Here, because the point nine map is a picture type specially supported by the Android system, if it is a point nine map, the repeated content is filled according to the preset horizontal and vertical iteration area in the picture when drawing. Here, if the first bitmap object Drawable is obtained by directly generating the first bitmap object Drawable according to the first bitmap pixel data Bitmap, the attribute of the point nine map is overwritten. Therefore, when the background of the picture is a nine-point map, the generated first bitmap pixel data Bitmap needs to be deleted.

In the loading process, in order to further reduce the cost of resource loading, the resource loading class can also be added as a unit, and an exception catching is added. The Try, Catch parcel captures an Out of Memorty exception (OOM, Out Of Memorty), and when an exception occurs, the current load is discarded. The background resources of the image to avoid system application crashes due to insufficient memory.

At this point, the loading process of the picture background setting is completed.

Correspondingly, when the picture resource is loaded for the loading of the picture content display, referring to FIG. 3, the loading method corresponding to the DecodeDrawableHelper.loadImage is:

Step S301, receiving a resource, and determining a resource type according to the resource ID.

Here, the different resource types correspond to different resource IDs. When the resource is determined to be the picture content display resource according to the resource ID, step S302 is performed. When the resource is determined to be the color value resource and the XML resource, step S303 is performed. The resource type includes a picture resource, a color value resource, and an XML resource. The picture resource may include: a normal picture and a point nine picture; and the color value resource includes a color value type such as RGB8, RGB4, and the like.

In step S302, it is determined whether the picture content display is loaded. When it is determined that the picture content display is not loaded, step S304 is performed. When the picture content display has been loaded, step S305 is performed.

Step S303, when it is determined that the resource is a color value resource and an XML resource, generate a corresponding bitmap object according to the color value resource and the resource ID corresponding to the XML.

Specifically, the corresponding bitmap object Drawable is obtained through the Resources.getDrawable(resId) method, and the The ImageView.setImageDrawable method assigns a bitmap object to a view that requires content display so that the view View can display the corresponding resource. Wherein, the resId represents a resource ID.

In step S304, the size of the view and the size of the image content to be displayed are obtained, and whether the image content display needs to be compressed according to the view size; when the image content display needs to be compressed, step 306 is performed; When the content display does not require compression, step 307 is performed.

Here, the size of the image content display is obtained in this step in order to reduce the memory occupation. The specific implementation manner is: setting whether to obtain only the boundary inJustDecodeBounds is true, when set to true, only the process of loading the background of the image is obtained. Long, wide, and high information displayed in the image content, without actually parsing the image content display. After reading the size of the image content display, set inJustDecodeBounds to false.

Step S305, when it is determined that the picture content display has been loaded, the second bitmap pixel data Bitmap displayed by the picture content is called from the bitmap set mLeakBitmaps. In order to reduce the occupied memory of the second bitmap pixel data Bitmap, in the embodiment, one pixel of the second bitmap pixel data Bitmap is set to occupy 2 bytes, for example, loading of the second bitmap pixel data Bitmap. The format can be Bitmap.Config.RGB_565, and the Bitmap.Config.RGB_565 occupies 2 bytes.

Step S306, compressing the background of the picture according to the second compression ratio, and compressing the picture content display, and generating a second bitmap pixel data Bitmap displayed by the picture content according to the compressed picture content; wherein the second compression The scale is calculated based on the image display size and view size.

Step S307, generating a second bitmap pixel data Bitmap displayed by the picture content according to the current picture content.

Step S308, after the second bitmap pixel data Bitmap displayed by the picture content is generated, the second bitmap pixel data Bitmap is buffered into the bitmap set, and it is determined whether the picture content display is a point nine map, such as determining When the picture content is displayed as a normal picture, step S309 is performed; if it is determined that the picture content is displayed as a point nine figure, step S310 is performed.

Step S309, when it is determined that the picture content is displayed as a normal picture, generating a third bitmap object Drawable according to the second bitmap pixel data Bitmap; assigning the third bitmap object Drawable to the display of the content of the picture to be displayed. View View so that the View View can display the image content display.

Step S310, when it is determined that the picture content is displayed as a point nine map, deleting the generated second bitmap pixel data Bitmap; searching and parsing the picture content display resource by using the resource ID to generate a fourth bitmap object; The fourth bitmap object Drawable is assigned to the view View that needs to display the image content display. Here, because the point nine map is a picture type specially supported by the Android system, if it is a point nine map, the repeated content is filled according to the preset horizontal and vertical iteration area in the picture when drawing. Here, if the third bitmap object Drawable is obtained by directly generating the third bitmap object Drawable according to the second bitmap pixel data Bitmap, the attribute of the point nine map is overwritten. Therefore, when the picture content display is a nine-point map, the generated second bitmap pixel data Bitmap needs to be deleted.

In the loading process, in order to further reduce the cost of resource loading, you can also add the exception capture to the resource loading class, and catch the OOM (Out Of Memorty) exception through the Try, Catch package. When you abandon loading the current image resource to avoid system application crashes due to insufficient memory.

At this point, the loading process of the picture content display is completed.

It should be noted that, in the embodiment, whether the background of the loaded image or the content of the loaded image is displayed, in the resource loading class, the same resource is only loaded once, which effectively reduces the repeated loading of the resource, and avoids memory jitter caused by repeated loading of the resource. Causes the loading process to be unstable.

Optionally, in order to recover the useless image resources in the bitmap set mLeakBitmaps, the memory management can be controlled to avoid application crash caused by insufficient memory. In this embodiment, the loader and the image content display loader are set in the background of the image. After being encapsulated into the image resource loading class, the program releaseSrc() that collects the image resource is further encapsulated into the image resource loading class, and the program for recovering the image resource shares a resource management interface with the program loaded by the image resource. The program releaseSrc() for reclaiming the picture resource is specifically implemented as follows:

Here, when the recovery timing of the preset picture resource is triggered, the resource recovery program is called to execute the recycle by the resource management interface to recover the useless bitmap data of the first bitmap pixel and the bitmap in the bitmap set mLeakBitmaps. One bitmap pixel data Bitmap. The recovery timing is specifically when the picture on the interface is deleted.

Step S102, loading a resource management interface for the picture resource loading class.

After the loading program of the picture background setting, the loading program of the picture content display, and the reclaiming program of the picture resource are encapsulated into the image resource loading class, the image resource loading interface IDecodeDrawableHelper needs to be encapsulated for the image resource loading class, and the image is needed. When the resource is loaded or the image resource is reclaimed, the image resource loading program in the resource loading class may be called to load the image resource through the resource management interface, or the image resource recycling program may be invoked through the resource management interface to the image resource. Recycle. In this way, the same resource management interface can be used to realize picture background setting, picture content display and image resource recycling, thereby realizing unified management of image resource loading and recycling.

Specifically, the encapsulation process of the resource management interface IDecodeDrawableHelper is as follows:

Public interface IDecodeDrawableHelper{

DecodeDrawableHelper getHelper();

Void releaseSrc();

}

It can be seen that under the resource management interface IDecodeDrawableHelper, there are two methods: the first is getHelper, which refers to the resource loading method under the loaded loading class; the second is releaseSrc, which refers to the method of reclaiming resources.

Step S103: Call the corresponding picture resource loading class through the resource management interface, and load the corresponding picture background and the picture content display.

In this step, when the loading program of the picture background setting and the loading program of the picture content display are encapsulated into the picture resource loading class; and the resource management interface IDecodeDrawableHelper corresponding to the picture resource loading class is encapsulated; The interface IDecodeDrawableHelper invokes the corresponding image resource loading class, and loads the corresponding image background and image content display. For the specific loading method, refer to steps 201-210 and steps 301-310; or pass the resource management interface IDecodeDrawableHelper according to a preset recycling time. The image resource recycling program is called to recover the useless image resource. For the specific method for recycling resources, refer to step S102.

In an actual application, the image resource loading method and the image resource recovery method described in step S102 can be applied to any View, ViewGroup, and base class BaseActivity, taking the BaseActivity of the Activity in a browser as an example. The specific implementation of the method of resource loading and the method of recovering image resources is as follows:

Get the image resource loading method under the packaged image resource loading class:

Image resource recycling method:

During the loading process, when the interface image is deleted, that is, when the activity onDestroy is called, the resource recycling method releaseSrc is used to recover the image resource, and the program of the calling process is implemented as follows:

@Override

Protected void onDestroy(){

super.onDestroy();

releaseSrc();

In the BaseActivity, as well as the class that inherits from BaseActivity, when loading the image resource, you only need to load the image background setting by calling getHelper().loadBackground, or load the image content display by calling getHelper.loadImage; When the image resource is triggered, the releaseSrc can be called to recycle the useless image resources whenever the trigger is triggered.

The embodiment further provides a device for loading a picture resource. As shown in FIG. 4, the device includes: a first encapsulating module 41, a second encapsulating module 42, a calling module 43, and a storage module 44;

The first encapsulation module 41 is configured to encapsulate a loading program of a picture background setting and a loading program for displaying a picture content into a picture resource loading class, where the picture resource generally includes a picture background setting and a picture content display, and the loading picture is loaded. When the resource is used, the background setting and the image content display need to be loaded. Therefore, the loading program of the image background setting and the loading program of the image content display are packaged into the image resource loading class Decode DrawableHelper, which is convenient for unified loading management.

After the first package module 41 encapsulates the load program of the picture background setting and the load program of the picture content display into the picture resource loading class Decode DrawableHelper, the bitmap set mLeakBitmaps needs to be established, and the storage module 44 can load the process. The bitmap pixel data Bitmap generated in the bitmap is stored in the pre-established bitmap set mLeakBitmaps.

Here, the first encapsulating module 41 encapsulates the loading program of the picture background setting and the loading program of the picture content display into the image resource loading class Decode DrawableHelper. The implementation program is as follows:

DecodeDrawableHelper.loadBackground

DecodeDrawableHelper.loadImage

Specifically, referring to FIG. 5, the first encapsulating module 41 includes: a first determining module 51, a first calling module 52, a first generating module 53, a second determining module 54, a first assigning module 55, and a first deleting module. 56, a second generation module 57 and a first capture module 58; wherein

When the picture resource is loaded as a loading of the picture background, the first determining module 51 is configured to receive a resource, and determine a resource type according to the resource ID. Here, since different resource types correspond to different resource IDs, the resource type can be determined according to the resource ID. The resource type includes a picture resource, a color value resource, and an XML resource. The picture resource may include: a normal picture and a point nine picture; and the color value resource includes a color value type such as RGB8, RGB4, and the like.

When the first determining module 51 determines that the resource is a background resource of the picture, it is also required to determine whether the background of the picture is loaded. When it is determined that the background of the picture is not loaded, the size of the view that needs to be displayed and the size of the background of the picture are obtained. The view size determines whether the picture background needs compression. When it is determined that the picture background needs to be compressed, the picture background is compressed according to the first compression ratio. Here, the first determining module 51 obtains the size of the background of the picture in order to reduce the memory occupation. The specific implementation manner is: the first determining module 51 sets whether to obtain only the boundary inJustDecodeBounds value is true, when set to true, the background image is loaded. In the process, only the length, width and height of the background of the picture will be obtained. Information without going to really parse the picture background. When the first determining module 51 reads the size of the background of the picture, set inJustDecodeBounds to false.

Optionally, when the first determining module 51 determines that the background of the picture has been loaded, the first calling module 52 is configured to invoke the first bitmap pixel data of the background of the picture from the bitmap set mLeakBitmaps. Bitmap. In order to reduce the occupied memory of the first bitmap pixel data Bitmap, in the embodiment, one pixel in the first bitmap pixel data Bitmap is set to occupy 2 bytes, for example, loading of the first bitmap pixel data Bitmap. The format can be Bitmap.Config.RGB_565, and the Bitmap.Config.RGB_565 occupies 2 bytes.

When the first determining module 51 determines that the background of the picture does not need to be compressed, the first generating module 53 is further configured to generate a first bitmap pixel data Bitmap of the picture background according to the current picture background.

After the first generation module 53 generates the first bitmap pixel data Bitmap of the picture background according to the current picture background, the storage module 44 caches the first bitmap pixel data Bitmap into the bitmap set mLeakBitmaps. .

After the first generation module 53 generates the first bitmap pixel data Bitmap of the background of the image according to the current background, the second determining module 54 is configured to determine whether the background of the image is a point nine map, such as determining When the background of the picture is a normal picture, the first bitmap object Drawable is generated according to the first bitmap pixel data Bitmap, and the first assignment module 55 assigns the first bitmap object Drawable to the image to be displayed. The View view of the background so that the View View can display the background of the image.

When the second determining module 54 determines that the background of the picture is a nine-point map, the first deleting module 56 is configured to delete the generated first bitmap pixel data Bitmap; the first generating module 53 further uses The first bitmap module 55 is further configured to assign the second bitmap object to the view View that needs to display the background of the image, by using the resource ID to find and parse the picture background resource. Here, because the point nine map is a picture type specially supported by the Android system, if it is a point nine map, the repeated content is filled according to the preset horizontal and vertical iteration area in the picture when drawing. Here, if the first bitmap object Drawable is obtained directly according to the first bitmap pixel data Bitmap to the first bitmap object Drawable, the attributes of the nine maps are overwritten. Therefore, when the background of the picture is a nine-point map, the generated first bitmap pixel data Bitmap needs to be deleted.

Optionally, when the first determining module 51 determines that the resource is a color value resource and an XML resource, the second generating module 57 is further configured to generate a corresponding bit according to the color value resource and the resource ID corresponding to the XML. The first evaluation module 55 is further configured to assign a corresponding bitmap object to a view that needs to display a background.

Specifically, when the first determining module 51 determines that the resource is a color value resource and an XML resource, the second generating module 57 acquires a corresponding bitmap object Drawable by using a Resources.getDrawable(resId) manner, where the first The assignment module 55 assigns the bitmap object Drawable to the view View so that the view View can display the corresponding resource. Wherein, the resId represents a resource ID.

Here, before the first assignment module 55 assigns the bitmap object Drawable to the view View, the first determining module 51 is further configured to: determine whether the SDK_INT in the system is greater than 16, when determining that the SDK_INT is greater than or equal to 16 , View calls the setBackground (drawable) method to get the bitmap object Drawable, using bitmap objects Drawable assigns a background to display the corresponding resource; when it is determined that the SDK_INT is less than 16, View calls the setBackgroundDrawable) (drawable) method to obtain the bitmap object Drawable, and uses the bitmap object Drawable to assign a background to display the corresponding resource. It should be noted that the background referred to herein refers to the display background of the display color value resource and the XML resource, which is different from the background image.

In addition, in the loading process, in order to further reduce the cost of resource loading, the first encapsulating module 41 further includes: a first capturing module 58 for the resource loading class as a unit, adding an exception capturing, through Try The Catch package catches an Out of Memorty (OOM) exception. When an exception occurs, the current image background resource is discarded to avoid the system application crash due to insufficient memory.

Correspondingly, when the picture resource is loaded as the loading of the picture content display, referring to FIG. 6, the first encapsulating module 41 further includes: a third determining module 61, a second calling module 62, a third generating module 63, and a a determining module 64, a second assigning module 65, a second deleting module 66, a fourth generating module 67, and a second capturing module 68;

The third determining module 61 is configured to receive a resource, and determine a resource type according to the resource ID. Here, different resource types correspond to different resource IDs, so the resource type can be determined according to the resource ID.

After receiving the resource, the third determining module 61 determines, according to the resource ID, that the resource is a picture content display resource, determines whether the picture content display is loaded, and determines that the picture content display is not loaded; and obtains a view view that needs to be displayed. The size and the size of the picture content display, determining whether the picture content display needs to be compressed according to the view size; when it is determined that the picture content display needs to be compressed, compressing the picture content display according to the second compression ratio, and displaying the picture content After the compression, the second bitmap pixel data Bitmap displayed on the image content is generated according to the compressed image content; wherein the second compression ratio is calculated according to the image content display size and the view size. Here, the third determining module 61 obtains the size of the picture content display in order to reduce the memory occupation. The specific implementation manner is: setting whether to obtain only the boundary inJustDecodeBounds value is true, when set to true, the process of loading the picture background In the middle, only the length, width, and height information of the image content display will be obtained, and the image content display will not be truly resolved. After reading the size of the image content display, set the value of inJustDecodeBounds to false.

When the third determining module 61 determines that the picture content display has been loaded, the second calling module 62 is configured to invoke the second bitmap pixel data Bitmap of the picture content display from the bitmap set mLeakBitmaps. In order to reduce the occupied memory of the second bitmap pixel data Bitmap, in the embodiment, one pixel of the second bitmap pixel data Bitmap is set to occupy 2 bytes, for example, loading of the second bitmap pixel data Bitmap. The format can be Bitmap.Config.RGB_565, and the Bitmap.Config.RGB_565 occupies 2 bytes.

When the third determining module 61 determines that the picture content display does not need to be compressed, the third generating module 63 displays a second bitmap pixel data Bitmap of the picture background according to the current picture content.

After the third generation module 63 generates the second bitmap pixel data Bitmap displayed according to the current picture content display, the second bitmap pixel data Bitmap is buffered into the bitmap set, the fourth determination. The module 64 is configured to determine whether the picture content is displayed as a point nine figure. If the picture content is determined to be a normal picture, the third generation module 63 is configured to generate a third bit according to the second bitmap pixel data. a drawing object Drawable; the second assigning module 65 assigns the third bitmap object Drawable to a view View that needs to display a picture content display, Enables the View View to display the image content display.

When the fourth determining module 64 determines that the picture content is displayed as a point nine map, the second deleting module 66 is configured to delete the generated second bitmap pixel data Bitmap; the third generating module 63 further The second bitmap function is further configured to assign the fourth bitmap object to the view View that needs to display the display of the image content. Here, because the nine-point map is a specially supported image type, if it is a nine-point map, the repeated content is filled according to the preset horizontal and vertical iteration regions in the image. Here, if the third bitmap object Drawable is obtained by directly generating the third bitmap object Drawable according to the second bitmap pixel data Bitmap, the attribute of the point nine map is overwritten. Therefore, when the picture content display is a nine-point map, the generated second bitmap pixel data Bitmap needs to be deleted.

Optionally, when the third determining module 61 determines that the resource is a color value resource and an XML resource, the fourth generating module 67 is further configured to generate a corresponding bitmap according to the color value resource and the resource ID corresponding to the XML. Object. The second assignment module 65 is further configured to assign a corresponding bitmap object to a view that needs to display a display of the displayed picture content.

Specifically, when the third determining module 61 determines that the resource is a color value resource and an XML resource, the fourth generating module 67 acquires a corresponding bitmap object Drawable by using a Resources.getDrawable(resId) manner, and the second assignment The module 65 assigns the bitmap object to the view that needs content display through the ImageView.setImageDrawable method, so that the view View can display the corresponding resource. Wherein, the resId represents a resource ID.

In addition, in the loading process, in order to further reduce the cost of resource loading, the first encapsulating module 41 further includes: a second capturing module 68, where the second capturing module 68 is used for the resource loading class, adding an exception capturing, through Try The Catch package captures insufficient OOM exceptions. When an exception occurs, it abandons loading the current image resource to avoid system application crashes due to insufficient memory.

Optionally, in order to recover the useless image resources in the bitmap set mLeakBitmaps, the memory management can be controlled to avoid application crash caused by insufficient memory, and the first encapsulating module 41 displays the loading program and the image content of the background setting of the image. After the loader is packaged into the image resource loading class, the program releaseSrc() for recycling the image resource is further encapsulated into the image resource loading class, and the program for recovering the image resource and the program loaded by the image resource are loaded. A resource management interface is shared, and the program releaseSrc() for reclaiming the picture resource is specifically implemented as follows:

Here, when the recovery timing of the preset picture resource is triggered, the recycle is cyclically executed to recover the useless first bitmap pixel data Bitmap and the first bitmap pixel data Bitmap in the bitmap set mLeakBitmaps. The recovery timing is specifically when the picture on the interface is deleted.

Optionally, after the first encapsulating module 41 encapsulates the loading program of the picture background setting, the loading program of the picture content display, and the reclaiming program of the picture resource into the picture resource loading class, the second encapsulating module 42 is used to: Loading a class to encapsulate a resource management interface for the image resource.

Specifically, when the first encapsulating module 41 encapsulates the loading program of the background setting of the picture, the loading program of the picture content display, and the reclaiming program of the picture resource into the picture resource loading class, the class encapsulation of the picture resource needs to be loaded. A resource management interface IDecodeDrawableHelper, when the image resource needs to be loaded or the image resource needs to be recycled, the image resource loading program in the resource loading class can be called to load the image resource through the resource management interface, or through the resource. The management interface calls the image resource recycling program to recycle the image resources. In this way, the same resource management interface can be used to realize picture background setting, picture content display and image resource recycling, thereby realizing unified management of image resource loading and recycling.

Specifically, the encapsulation process of the resource management interface IDecodeDrawableHelper by the second encapsulation module 42 is as follows:

Public interface IDecodeDrawableHelper{

DecodeDrawableHelper getHelper();

Void releaseSrc();

}

The first encapsulating module 41 encapsulates the loading program of the picture background setting and the loading program of the picture content display into the picture resource loading class; the second encapsulating module 42 encapsulates the resource management interface IDecodeDrawableHelper corresponding to the picture resource loading class. Then, the calling module 43 can call the corresponding picture resource loading class through the resource management interface, and load the corresponding picture background and picture content display. For the specific loading process, refer to the above; or the calling module 43 may also invoke the image resource recycling program by using the resource management interface IDecodeDrawableHelper according to a preset recycling time to recover useless image resources, and the specific recycling resource process may also be referred to. Above.

In practical applications, the image resource loading process and the image resource recycling process described above can be applied to any View, ViewGroup, and base class BaseActivity, taking the BaseActivity of the Activity in a browser as an example, the image resource. The specific implementation of the loading process and the process of image resource recycling is as follows:

Image resource recycling method:

During the loading process, when the interface image is deleted, that is, in the Activity onDestroy, the calling module 43 may call the resource recycling method releaseSrc to recover the image resource, and the calling process is implemented as follows:

@Override

Protected void onDestroy(){

super.onDestroy();

releaseSrc();

The invention has the following beneficial effects or advantages:

The invention discloses a method for loading a picture resource. Before loading the picture resource, the loading program of the picture background setting and the loading program of the picture content display are encapsulated into the picture resource loading class, and the image resource loading class is encapsulated. The resource management interface; in this way, the resource management interface includes two loaders: a loader for setting the background of the image and a loader for displaying the image content; when the image resource needs to be loaded, whether the image background is loaded or the image content is loaded The service layer can call the corresponding image resource loading class through the resource management interface, and load the corresponding image background and the image content display, thereby optimizing the resource loading process and reducing the cost of resource loading. Moreover, by adding an exception capture to the resource loading class, the exceptions that occur during the loading process can be uniformly captured and processed, thereby further reducing the cost of resource loading.

When loading the background of the image or loading the content of the image, in the resource loading class, the same resource is only loaded once, which effectively reduces the repeated loading of the resource, and avoids the instability of the loading process caused by memory jitter caused by repeated loading of the resource. In addition, the method stores the generated bitmap pixel data in the loading process into the bitmap set by pre-establishing the bitmap set, implements memory management controllable, and encapsulates the resource recovery program into the resource loading class. And the recycling opportunity is added in the resource recycling program. When the recycling opportunity is triggered, the resource recycling program is called through the same resource management interface to timely recycle the useless image resources in the bitmap collection, thereby realizing the resource recovery and controllable. It fundamentally solves the OOM problem caused by the lack of NativeCache. It also realizes unified management of resource loading and recycling.
