Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described through embodiments with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of an Android frame animation execution method according to an embodiment of the present invention, where this embodiment is applicable to a situation where contents of a frame animation are dynamically changed in a frame animation execution process, and the method may be implemented by a terminal, and may specifically be implemented by software and/or hardware in the terminal.
Referring to fig. 1, the Android frame animation execution method includes the following steps:
s1, receiving an opening instruction, acquiring a first information object according to the opening instruction, initializing the information identifier of the first information object to be in a frame animation opening state, and sending the initialized information identifier of the first information object to a message processing function of the Handler object.
The opening instruction can be understood as an instruction for opening the Android frame animation and executing the frame animation; the starting instruction may be generated by pressing a physical key of the Android terminal, or by clicking a virtual key of a screen of the Android terminal, which is not specifically limited herein. The first information object may be a new message object or an instantiated object; the first information object may be an instantiated object, so as to reduce resource overhead for the system and improve system operation efficiency.
By acquiring the first information object and initializing the information identifier of the first information object, the processing message function of the Handler object can perform an animation opening operation according to the information identifier of the first information object after receiving the first information object, and the specific animation opening operation can be referred to in step S2.
Optionally, fig. 2 is a flowchart of S1 in the Android frame animation execution method according to the first embodiment of the present invention, where the flowchart includes:
and S11, receiving an opening instruction, and calling an information acquisition method according to the opening instruction to acquire the first information object.
The information obtaining method may specifically be:
1.Message msg10＝new Message()；
2.Message msg11＝Message.obtain()；
3.Message msg12＝handler.obtainMessage()；
the method 1 is to create a Message object, the method 2 is to return a Message instance from the whole Message pool, the Message object can be prevented from being repeatedly created through the Message.
The object () is a static method, and only when the Message pool is empty, a Message object is newly created, and if the Message pool is not empty, the Message objects are all instances taken from the Message pool, so that the Message objects are repeatedly used, the resource overhead of the system is reduced, and the system operation efficiency is improved.
And S12, calling an information identifier initialization method to initialize the information identifier of the first information object to the frame animation starting state value.
The information identifier initialization method may specifically be:
msg1.what＝1；
wherein, 1 represents the value of the open state of the frame animation, and the value may also be a value corresponding to other preset open states of the frame animation, for example, 2, 3, 4, etc., and the information for identifying the first object information identifies the open state of the frame animation. By initializing the information identifier of the first information object to a value corresponding to a preset frame animation open state (namely, a frame animation open state value), when the message processing function of the Handler object receives the first information object, the frame animation open operation can be performed according to the information identifier of the first information object.
And S13, calling an empty message sending method of the Handler object to send the first information object after the information identifier is initialized to a message processing function of the Handler object.
The method for sending the air message of the Handler object may specifically be:
mHandler.sendEmptyMessage(msg1)；
the msg1 is the name of the first information object, which is used to represent the first information object, and the name of the first information object may also be other names, and is not limited to msg 1; the mHandler is the name of a Handler object, the mHandler represents an object of a Handler class, and the name of the Handler object can be other names and is not limited to the mHandler; by adopting the sendEmptyMessage method, the first information object can be known to be a null message with the message identifier being the animation starting state value, and the speed of message transmission and processing can be increased by sending the null message, so that the animation execution efficiency is increased.
Through the method for sending the empty message of the Handler object, the first information object can be sent to the message processing function of the Handler object, so that the message processing function of the Handler object can successfully receive the first information object.
And S2, when the message processing function of the Handler object judges that the received information identifier of the first information object is in the frame animation starting state, acquiring a second information object, initializing the information identifier of the second information object to be in the frame animation executing state, and sending the second information object after the information identifier initialization to the message processing function of the Handler object.
After the message processing function of the Handler object receives the first information object, the information identifier of the received first information object may be determined, and when the information identifier of the first information object is in a frame animation open state, a frame animation open operation may be performed, where the frame animation open operation specifically may be:
and acquiring a second information object, initializing the information identifier of the second information object into a frame animation execution state, and sending the second information object after the information identifier is initialized to a message processing function of the Handler object.
By acquiring the second information object and initializing the information identifier of the second information object, the message processing function of the Handler object can perform a frame animation operation according to the information identifier of the second information object after receiving the second information object, and the specific frame animation operation can be performed in step S3.
Optionally, fig. 3 is a flowchart of S2 in the Android frame animation execution method according to the first embodiment of the present invention, where the flowchart includes:
and S21, when the message processing function of the Handler object judges that the received information identifier of the first information object is in the frame animation opening state, calling an information acquiring method to acquire a second information object.
The message processing function of the Handler object judges whether the received information identifier of the first information object is in a frame animation starting state, namely, the message processing function of the Handler object judges whether msg1.what of the first information object is in the frame animation starting state value, and if yes, the received information identifier of the first information object can be judged to be in the frame animation starting state.
The information acquiring method for acquiring the second information object is the same as the information acquiring method in step S11, specifically, see step S11, it is to be noted that the second information object is two different information objects from the first information object, and specifically, the object name of the second information object may be considered to be different from the object name of the first information object.
And S22, calling an information identifier initialization method to initialize the information identifier of the second information object to the frame animation execution state value.
The information tag initialization method is the same as the information tag initialization method in step S12, and particularly, referring to step S12, it should be noted that the information tag of the second information object is a frame animation executing state value, which is different from the information tag of the first information object being a frame animation open state value, and the frame animation executing state value and the frame animation open state value cannot be preset to the same value.
And S23, calling an empty message sending method of the Handler object to send the second information object after the information identifier is initialized to a message processing function of the Handler object.
The empty message sending method is consistent with the empty message sending method in step S13, and specifically, refer to step S13. Through the method for sending the empty message of the Handler object, the second information object can be sent to the message processing function of the Handler object, so that the message processing function of the Handler object can successfully receive the second information object.
And S3, when the message processing function of the Handler object judges that the received information mark of the second information object is the frame animation execution state, defining the frame animation progress of the Handler object and initializing the frame animation progress to 0.
After the message processing function of the Handler object receives the second information object, the information identifier of the received second information object may be determined, and when the information identifier of the second information object is a frame animation executing state, a frame animation executing operation may be executed, where the frame animation executing operation may specifically be: a frame animation progress of the Handler object is defined and initialized to 0. By defining the frame animation progress and initializing the frame animation progress to 0, the frame animation progress can be updated to control the pictures to be sequentially called from the picture set corresponding to the frame animation, so that the frame animation execution is realized.
And S4, circularly sending the second information object after the information identifier initialization to the message processing function of the Handler object every other execution period of the frame animation.
The animation execution period may be predefined, and may be understood as an update period of a frame animation progress, or may be understood as a period of a timer constructed by a Handler mechanism. The second information object is sent in a circulating mode every other frame animation execution period, so that the frame animation progress can be updated regularly, and the frame animation execution fluency is guaranteed.
Optionally, S4 specifically includes:
and calling an empty message delayed sending method loop of the Handler object to send the second information object after the information identifier initialization to a message processing function of the Handler object every other execution period of the frame animation.
The delayed sending method of the air message of the Handler object may specifically be:
mHandler.sendEmptyMessageDelay(msg2,ANIM_DURATION)；
the msg2 is a name of the second information object, which is used to represent the second information object, and the name of the second information object may also be other names, and is not limited to msg 2; the ANIM _ DURATION is a name of an execution period of the frame animation, and is used for representing the execution period of the frame animation, and the name of the execution period of the frame animation may be other names, and is not limited to ANIM _ DURATION; the mHandler is the name of a Handler object, the mHandler represents an object of a Handler class, and the name of the Handler object can be other names and is not limited to the mHandler; by adopting the sendEmptyMessageDelay method, the second information object can be known to be a null message with the message identifier being the frame animation execution state value, and the speed of message transmission and processing can be increased by sending the null message, so that the animation execution efficiency is increased.
Through the delayed sending method of the empty message of the Handler object, the second information object can be circularly sent to the message processing function of the Handler object every other execution period of the frame animation, so that the message processing function of the Handler object can successfully receive the second information object every other execution period of the frame animation, and the frame animation progress is updated after the second information object is received, so that the frame animation can be normally executed.
S5, when the message processing function of the Handler object receives a second information object after the information identification initialization, updating the frame animation progress, calling the pictures in the picture set corresponding to the sequence value and the updated frame animation progress, and stopping sending the second information object after the information identification initialization until the updated frame animation progress is equal to the capacity value of the picture set;
when a frame animation change message is received in the frame animation execution process, whether a change condition is met is judged, and if yes, a picture set corresponding to the frame animation is changed according to the frame animation change message.
After the frame animation progress is defined and initialized, the second information object is circularly sent to the message processing function of the Handler object through the empty message delay sending method of the Handler object, so that the message processing function of the Handler object can successfully receive the second information object every other execution period of the frame animation, and the frame animation progress is added with 1 after the second information object is received.
The method comprises the steps of calling a picture corresponding to a sequence value and an updated frame animation progress in a picture set, wherein the picture can be understood as calling the nth picture in the picture set when the updated frame animation progress is n; the sequence value of the picture set is a positive integer starting from 0, so that the sequence value corresponding to the nth picture is n-1, that is, when the frame animation progress is n after updating, the picture with the sequence value of n-1 in the picture set is called.
And stopping sending the second information until the progress of the updated frame animation is equal to the capacity value of the picture set, and executing to finish the Android frame animation. For example, when the volume value of the picture set is 24, that is, the picture set corresponds to 24 pictures, the execution process of the frame animation may be understood as: if the frame animation progress is updated to 1, calling the 1 st picture from the picture set corresponding to the frame animation; if the frame animation progress is updated to be 2, calling the 2 nd picture from the picture set corresponding to the frame animation; and (4) calling the 24 th picture from the picture set corresponding to the frame animation every time the frame animation progress is increased by 1 until the frame animation progress is updated to be 24, thereby finishing the execution of the frame animation.
The volume value of the picture set may be understood as the size of the picture set, and may also be understood as the number of corresponding pictures contained in the picture set. The capacity value of the picture set can be obtained by calling the following method:
int i＝listImageIds.Count；
the listImageIds is a name of the picture set, and is used for representing a predefined picture set, and the name of the picture set may be other names, and is not limited to the listImageIds; the method comprises the steps that a volume value of a picture set can be obtained through a Count method, and the volume value is assigned to a defined integer variable i; when the frame animation change message is received and the frame animation is changed according to the frame animation change message, the capacity value combined with the picture needs to be obtained again so as to ensure that the frame animation progress can be updated to the capacity value of the changed frame animation, and therefore the normal execution of the changed frame animation is ensured.
Optionally, the calling of the picture in which the sequence value corresponds to the updated frame animation progress in the picture set includes:
and calling a picture information calling method to call picture information of which the sequence value corresponds to the updated frame animation progress in the picture set, and calling a bitmap obtaining method to obtain a picture corresponding to the picture information.
Wherein, the picture information can be ID information of the picture; and each picture has a unique ID number corresponding to the picture in the Android system, so that the picture can be identified by the ID number of the picture. The picture ID is added to the picture set, so that the picture corresponding to the picture set is conveniently acquired, the memory overhead is greatly reduced, and the picture set can be maintained by maintaining the picture ID, so that the picture in the picture set is more favorably maintained.
The picture information calling method may specifically be:
listImageIds.get(index)；
the listImageIds is a name of the picture set, and is used for representing a predefined picture set, and the name of the picture set may be other names, and is not limited to the listImageIds; wherein, index represents index number, and the index number can be specifically the value of frame animation progress minus 1 after updating in the execution process of frame animation; and acquiring the ID information of the pictures with the sequence values equal to the index numbers in the picture set by using a get method. By acquiring the picture ID information in the picture set, a bitmap acquisition method can be called to acquire the bitmap picture corresponding to the picture ID information.
The bitmap acquisition method may specifically be:
Bitmapfactory.DecodeResource(imageId)；
the imageId is the name of the picture ID information and is used for representing the ID information of the picture, and the name of the picture ID information can be other names and is not limited to the imageId; acquiring a bitmap picture corresponding to the picture ID information by a DecodeResource method; the Bitmap is a Bitmap class, and after a Bitmap object named mBitmap in the Bitmap class is constructed, the Bitmap object can be understood as a Bitmap picture.
Optionally, after the picture with the sequence value corresponding to the updated frame animation progress in the picture set is called, the method further includes:
and calling a bitmap destroying method to destroy the fetched picture corresponding to the animation schedule of the frame before updating.
Because the called bitmap picture occupies a large memory, if the called picture is not destroyed in time, the situations of memory overflow, abnormal execution of frame animation and the like may occur. Therefore, after the pictures with the sequence values corresponding to the updated frame animation progress in the picture set are called, the previously called pictures can be preferably destroyed to release the memory and ensure the normal execution of the frame animation.
The bitmap destroying method may specifically be:
mBitmap.recycle()；
the mBitmap is the name of the bitmap picture and is used for representing the bitmap picture, and the name of the bitmap picture can be other names and is not limited to the mBitmap; the memory occupied by the called bitmap picture can be recycled through the recycle method, so that the destroying operation of the called picture is realized.
Optionally, when a frame animation change message is received in the frame animation execution process, determining whether a change condition is satisfied, and if so, changing a picture set corresponding to the frame animation according to the frame animation change message, including:
when a frame animation change message is received in the frame animation execution process, determining the change position and the change information of a picture set corresponding to the frame animation according to the frame animation change message; acquiring the animation progress of the current frame according to a preset protocol interface, and judging whether the animation progress of the current frame is before the position is changed; and if so, changing the picture set corresponding to the frame animation according to the change message.
Wherein, the change position can be understood as a corresponding sequence value in the picture set which needs to be changed; the change information may include operation instructions such as addition, deletion, and replacement, and bitmap pictures and picture ID information corresponding to the operation instructions.
The protocol interface definition method may specifically be:
the method includes the following steps that IAnim is the name of a protocol interface and is used for representing the protocol interface, the name of the protocol interface can be other names, and the method is not limited to IAnim; the starting onStart, executing onsegress and ending onEnd states of the frame animation can be transmitted through the protocol interface; in the frame animation execution process, the progress parameter progressive value of the frame animation can be transmitted to a caller, so that the caller can obtain the progress state of the current frame animation execution, and selectively perform the frame animation updating operation according to the progress state.
The caller can inherit the protocol interface IAnim by means of instance, for example, it can be public class a instance IAnim, where a can refer to the type of the caller; after inheriting the interface IAnim, the protocol methods onStart, onsegress, and onEnd in the protocol may be overwritten, so that each execution state of the frame animation may be obtained.
When the caller initialization operation is performed, the caller registration can be performed in the information sender, and specifically, the caller mIAnim can be registered in the information sender by a register (iam mIAnim) registration method, so that the caller can acquire the execution state of the frame animation through the protocol interface.
If the current frame animation progress is before the change position, namely the frame animation execution flow does not reach the change position, the change operation can be carried out at the change position according to the change information; if the current frame animation progress is after the position is changed, that is, the frame animation execution flow has already executed the change position, the change operation can be performed at the change position according to the change information when the frame animation execution is finished. The changing of the picture set corresponding to the frame animation according to the change message may include operations of adding pictures, deleting pictures, replacing pictures, and the like at a change position.
Optionally, before S1, the method further includes:
calling a Handler object definition method to define a Handler object of the Handler type, and rewriting a message processing function in the Handler object; calling a constant definition method to define the execution period of the frame animation; and calling a set definition method to define a picture set of the frame animation, and calling a picture information adding method to add picture information in the picture set.
The method for calling the Handler object definition specifically may be:
Private Handler mHandler＝new Handler(){
handleMessage(Message msg){
