Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart of a picture calling method according to an embodiment of the present invention is shown, which may specifically include the following steps:
Specifically, in the embodiment of the present invention, the method in the embodiment of the present invention may be applied to a mobile terminal or other devices, for example: tablet, PC, etc.
Taking the mobile terminal as an example, in an embodiment, if the user opens the application program, the user instruction may be triggered by the mobile terminal to instruct the application program to use at least one picture in the local storage of the mobile terminal. After receiving the user instruction, the mobile terminal can determine the picture set which needs to be called by the current mobile terminal.
In another embodiment, the mobile terminal may also automatically trigger the picture call process according to a preset rule. For example, the following steps are carried out: after the operator presets the application program A to start, at least one picture stored locally is automatically transferred. Then, after detecting that the application program a is started, the mobile terminal determines that the at least one picture needs to be called currently.
Specifically, in the embodiment of the present invention, when detecting that the picture set needs to be called currently, the mobile terminal extracts at least one specified picture from the local storage to form the picture set.
Specifically, in the embodiment of the present invention, the mobile terminal detects whether the size of the memory required by the picture set exceeds a predetermined threshold. In the embodiment of the present invention, the predetermined threshold may be set by a user according to actual requirements, i.e. factors such as processing capability of the device, which is not limited by the present invention.
And 103, if not, caching the picture set into a system-specified memory area, so that the application program calls the picture set from the system-specified memory area.
Specifically, in the embodiment of the present invention, if the mobile terminal detects that the size of the memory required by the picture set does not exceed the predetermined threshold, the technical solution in the prior art embodiment may be used, that is, the picture set is cached in the memory area specified by the system, and in the subsequent processing process, the application program may directly call the picture set from the memory area specified by the system.
And 104, if yes, caching the picture set into a pre-established memory area.
Specifically, in the embodiment of the present invention, if the mobile terminal detects that the size of the memory required by the picture set exceeds the predetermined threshold, the picture set is cached in the memory area created in advance. In the embodiment of the present invention, when the system in the mobile terminal detects that there is a picture set to be cached (i.e. a picture set whose size exceeds a predetermined threshold), a memory area is created in the memory. In one embodiment, when the system creates the memory area, the memory area may be created according to the size of the picture set. In another embodiment, the size of the memory area may be set in advance by an operator, and the system creates the memory area according to the setting of the operator. In another embodiment, the location of the memory area in the memory may be randomly selected by the system, which is not limited in the present invention.
And 105, creating a bitmap file corresponding to each picture in the picture set one by one in the memory area so that the application program calls the bitmap file from the memory area.
Specifically, in the embodiment of the present invention, the mobile terminal performs subsequent operations in the created memory area, specifically: and the mobile terminal creates a bitmap file corresponding to each picture one by one according to each picture in the picture set. The bitmap file may have a specified format, such as: in Drawable format, so that an application can call the bitmap file directly from a pre-created memory area.
And step 106, if the application program is monitored to be closed, emptying and releasing the memory area, and deleting bitmap information, wherein the bitmap information is information generated when a bitmap file is created.
Specifically, in the embodiment of the present invention, the mobile terminal monitors the state of the application program in real time, and if it is monitored that the application program is closed, the mobile terminal will empty the memory area, that is, delete the picture set, the bitmap file, and the like in the memory area. Meanwhile, the mobile terminal deletes the bitmap information generated in the process of creating the bitmap file. The bitmap information includes, but is not limited to: and the bitmap object is used for identifying the reference relation of the application program to the bitmap file.
According to the technical scheme, the memory area which is created in advance is emptied and released, so that the problem of overflow of the system memory can be effectively prevented. And in the process of calling the picture, the picture set and related resources are cached in the special memory area, so that cache data are not generated in a local cache, the pre-created memory area is emptied and released after the picture is used, and the related bitmap information is deleted, so that when other application programs call the picture again, the picture cannot be guided to the deleted memory area, therefore, on the premise of ensuring the picture calling efficiency, the problem of abnormal error reporting of a system possibly occurring is effectively solved, the stability of the system is improved, and the user experience is improved.
Example two
Referring to fig. 2, a flowchart of a picture calling method according to an embodiment of the present invention is shown, which may specifically include the following steps:
Specifically, in the embodiment of the present invention, the method in the embodiment of the present invention may be applied to a mobile terminal or other devices, for example: tablet, PC, etc. Taking the mobile terminal as an example, in an embodiment, if the user opens the application program, the user instruction may be triggered by the mobile terminal to instruct the application program to use at least one of the local storages of the mobile terminal. After the mobile terminal receives the user instruction, the fact that the current mobile terminal needs to call the picture can be determined.
In another embodiment, the mobile terminal may also automatically trigger the picture call process according to a preset rule. For example, the following steps are carried out: after the operator presets the application program A to start, the picture set is automatically transferred. Then, after detecting that the application program a is started, the mobile terminal determines that at least one picture in the mobile terminal needs to be called currently.
Specifically, when the mobile terminal detects that at least one picture in the mobile terminal needs to be called, the mobile terminal queries the target storage space in the local storage according to the picture. The target storage space is used for storing resource files. In one embodiment, the way to query the target storage space may be: and searching according to the identification information of the storage space. In another embodiment, the way to query the target storage space may also be: and searching according to the content in the storage space. In embodiments of the present invention, resource files include, but are not limited to: media files such as pictures, animations, etc.
The mobile terminal extracts at least one picture and forms a picture set.
Specifically, in the embodiment of the present invention, the mobile terminal detects whether the size of the memory required by the picture set exceeds a predetermined threshold. If yes, go to step 203. If not, the subsequent processing can be performed on the picture according to the caching mode in the embodiment of the prior art. That is, the picture set is cached in the memory area specified by the system, and in the subsequent processing process, the application program can directly call the picture set from the memory area specified by the system.
In the embodiment of the present invention, the predetermined threshold may be set by a user according to actual requirements, i.e. factors such as processing capability of the device, which is not limited by the present invention.
Specifically, in the embodiment of the present invention, if the mobile terminal detects that the size of the memory required by the picture set exceeds the predetermined threshold, the picture set is cached in the memory area created in advance. In the embodiment of the present invention, when the system in the mobile terminal detects that there is a picture set to be cached (i.e. a picture set whose size exceeds a predetermined threshold), a memory area is created in the memory. In one embodiment, when the system creates the memory area, the memory area may be created according to the size of the picture set. In another embodiment, the size of the memory area may be set in advance by an operator, and the system creates the memory area according to the setting of the operator. In another embodiment, the location of the memory area in the memory may be randomly selected by the system, which is not limited in the present invention.
Specifically, in the embodiment of the present invention, the mobile terminal may create an intermediate bitmap file corresponding to each picture according to each picture in the picture set. The intermediate bitmap file may be generated by the following statements:
Bitmap bmp＝BitmapFactory.decodeResource(res,R.drawable.test)
Specifically, in the embodiment of the present invention, the mobile terminal generates a bitmap object corresponding to each intermediate bitmap file one to one. In an embodiment of the present invention, the bitmap object is used to identify an intermediate bitmap file. That is, the bitmap object is an index of the intermediate bitmap file, and the application program can search for the bitmap file according to the bitmap object (since the intermediate bitmap file is encapsulated as the bitmap file in the subsequent step, the application program searches for the bitmap file when calling according to the bitmap object), and calls the corresponding bitmap file. The "bmp" in the above statement is the bitmap object in the embodiment of the present invention.
Specifically, in the embodiment of the present invention, step 206 specifically includes:
step 2061, call package statement.
Step 2062, according to the at least one bitmap object, encapsulating each of the at least one intermediate bitmap file into a bitmap file with a drawable format through an encapsulation statement.
Specifically, the mobile terminal encapsulates each generated intermediate bitmap file into a bitmap file with a specified format, i.e., a drawable format. Further, in the embodiment of the present invention, the mobile terminal encapsulates the middle bitmap file into a bitmapstrawable format. Therefore, the application program can directly use the bitmap file, and the processing efficiency of the application program is improved. Specifically, the encapsulation process can be implemented by the following statements:
pngdrawable＝new BitmapDrawable(bmp)；
that is, in the embodiment of the present invention, the mobile terminal encapsulates the middle bitmap file into a bitmap drawable format according to the bitmap object (bmp).
Subsequently, the application may call the bitmap file by referencing a function. The specific implementation can be realized through the following statements:
tv.setBackgroundDrawable(pngdrawable)。
therefore, it is seen that in the foregoing embodiments, the picture calling method in the embodiments of the present invention calls a picture set, dynamically creates a memory area for caching the picture set and a bitmap object, a bitmap file, and the like associated with the picture set, and after the application is called this time, clears all resources in the memory area, deletes the resources and a corresponding reference relationship, and the like. Therefore, the invention can generate new resources in the pre-created memory area when calling each time, thereby avoiding the utilization of the following in the picture calling method in the prior art: getResources (). getdrawable (id) statement, cache the picture locally, and cache resources will appear in the calling process of the application program, which causes the next time the application program directly returns to the cache resources in the calling process, thus causing the problem of system exception. The specific deletion method is as follows:
Specifically, in the embodiment of the present invention, if it is monitored that the application program is closed, the memory area is located according to at least one bitmap object. Then, the mobile terminal clears and releases the memory area.
Specifically, in the embodiment of the present invention, step 207 specifically includes:
in the substep 2071, if it is detected that the application is closed, the picture set and the bitmap file cached in the local memory are deleted.
Specifically, in the embodiment of the present invention, the mobile terminal monitors the state of the application program in real time, and if it is monitored that the application program is closed, the mobile terminal deletes the bitmap file and the image set, which are cached in the local memory.
Specifically, the mobile terminal in the embodiment of the present invention deletes the bitmap file by the following statements:
pngdrawable＝null；
and deleting the picture set in the cache by:
bitmap.recycle()；
substep 2072, deleting at least one bitmap object.
Specifically, in the embodiment of the present invention, the mobile terminal further deletes the generated at least one bitmap object, and if another application program calls the picture set again, since the bitmap object is deleted, the application program regenerates the bitmap file by reusing the picture calling method in the embodiment of the present invention, and cannot find the pre-created memory area according to the deleted bitmap object, and causes a problem of abnormal error reporting of the system. The bitmap object is deleted by:
bitmap＝null
substep 2073, the nulling application calls a reference function used when the bitmap file.
Specifically, in the embodiment of the present invention, the mobile terminal further extracts the reference function of the bitmap file from the nulling application program, thereby further avoiding the occurrence of the problem of abnormal error reporting of the system. Specifically, the null reference function can be implemented by:
tv.setBackgroundDrawable(null)；
in addition, in a preferred embodiment of the present invention, the mobile terminal may also clear application level garbage, such as: registries, reference relationships, etc. In another embodiment, the mobile terminal may perform overall garbage cleaning, i.e. cleaning the application layer and the bottom layer. Therefore, information possibly related to the generated bitmap file is cleaned, the risk of abnormal error reporting of the system is further reduced, and the stability of the system is improved.
In summary, according to the technical solution in the embodiment of the present invention, the pre-created memory area is cleared and released, so that the problem of system memory overflow can be effectively prevented. And in the process of calling the picture, the picture set and related resources are cached in the special memory area, so that cache data are not generated in a local cache, the pre-created memory area is emptied and released after the picture is used, and the related bitmap information is deleted, so that when other application programs call the picture again, the picture cannot be guided to the deleted memory area, therefore, on the premise of ensuring the picture calling efficiency, the problem of abnormal error reporting of a system possibly occurring is effectively solved, the stability of the system is improved, and the user experience is improved.
