Scheme and effect are clearer, clear and definite, and the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should manage
Solution, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
In the present invention, using such as " module ", " part " or " unit " for representing element suffix only for favourable
In the explanation of the present invention, itself does not have specific meaning.Therefore, module ", " part " or " unit " can mixedly make
With.
The method of the invention can be used for the terminal unit with android system, and described terminal unit can be with each
Kind of form is implementing.For example, the terminal described in the present invention can include such as mobile phone, smart phone, notebook computer,
Digit broadcasting receiver, PDA (personal digital assistant), PAD (panel computer), PMP (portable media player), navigation dress
The mobile terminal put etc. and the fixed terminal of such as digital TV, desk computer etc..However, those skilled in the art will
It is understood by, in addition to being used in particular for the element of mobile purpose, construction according to the embodiment of the present invention also can be applied
Terminal in fixed type.
Below in conjunction with the accompanying drawings, by the description to embodiment, content of the invention is described further.
Refer to Fig. 1, the stream of the preferred embodiment of the animation method for drafting based on synchronizing signal that Fig. 1 provides for the present invention
Cheng Tu.Methods described includes：
S100, when receive draw animation instruction when, by the synchronizing signal of Choreographer module monitoring system, its
In, described synchronizing signal carries out the refresh signal of display when animation renders for system.
Specifically, described Choreographer module is a message handling device, for according to synchronizing signal（Vsync,
vertical synchronization）Execution readjustment algorithm.Described readjustment algorithm includes event call-back method, animation readjustment side
Method and drafting callback method.In the present embodiment, when adding animation, the action adding animation is sent to Choreographer
Module, Choreographer module is opened according to the action adding animation and is received synchronizing information.Wherein, described synchronizing signal
Vsync is synchronous with the frame number of display that is to say, that described synchronizing signal is signal produced by display refreshing.
Described when receive draw animation instruction when be worth be terminal unit start animation draw function, for example, start
The application APP of drafting animation, terminal is needed to need in itself to draw animation etc..
In the present embodiment, because the APP that terminal unit loads can not directly invoke the Choreographer mould of system
Block, thus including an invocation step when terminal unit starts APP, is specifically as follows：
When terminal unit starts, monitor terminal equipment starts application program operation；
When listening to the operation that terminal unit starts application program, obtain the Choreographer module of system, and will be described
Choreographer module is configured at the main thread Message Queuing of described application.
Specifically, when terminal unit starts, the main thread Message Queuing of all applications that terminal starts adds institute
State Choreographer module, synchronous for being received by Choreographer module when application program carries out animation drafting
Signal, carries out animation interpolation according to described synchronizing information.So can ensure that the application program animation used of installing terminal equipment
The frame number of interpolation and display is synchronous, it is to avoid the interpolation that produces because interim card in system uneven so that being shown to use
The problem of interim card in the picture at family.
S200, when listening to described synchronizing signal, call the FrameCallback interface of Choreographer module
Carry out interpolation operation.
Specifically, the callback method of the offer that described FrameCallback interface provides for Choreographer module
Class；For animation interpolation is carried out using callback method according to synchronizing signal.That is, when receiving synchronizing signal, passing through
The FrameCallback interface of Choreographer module, carries out animation interpolation according to synchronizing signal using callback method.Institute
State the message mechanism that callback method is using Android system, in advance described callback method is arranged disappearing to the main thread of application
Breath queue, when receiving synchronizing signal, adjusts back described FrameCallback interface.
Described FrameCallback interface preset configuration Cyclic Interpolation operational order, to realize how many interpolation, solves described
FrameCallback is only capable of carrying out an interpolation operation when configuring described callback method it is impossible to repeat to call repeatedly just can interpolation
The problem completing.In the present embodiment, the mode of described FrameCallback interface recurrence, that is, in FrameCallback
It is reconfigured at a FrameCallback, realize the loop configuration of FrameCallback interface, this ensures that there and do not have when interpolation
When completing, circulation is not exited it is achieved that repeating to call FrameCallback interface, realizes repeatedly inserting in animation drawing process
Value Operations.
Due to there may be delay when calling FrameCallback interface or leaking the problem called, thus calling
The FrameCallback interface of Choreographer module can also include after carrying out interpolation operation:Record and described currently insert
The time that value is drawn, judge whether carry out interpolation operation next time in Preset Time, if inserted in Preset Time next time
Value Operations, then carry out clamper process.
Specifically, described Preset Time can with display refreshing time difference, that is, the previous frame of display and present frame when
Between differ from it is also possible to be greater than display refreshing time difference, such as 50 milliseconds, 60 milliseconds etc..In the present embodiment, described Preset Time
Section can be 60 milliseconds.And the frame frequency of display refreshing is generally 60Hz in Android system, then previous frame and present frame
Time difference is 16.6 milliseconds.Thus, after carrying out an animation drafting, obtain described current interpolation operation and grasp with last interpolation
The time interval made, and described time interval and preset time period are compared；When described time interval is more than described presetting
During the time period, the FrameCallback interface of Choreographer module is called to carry out preset times interpolation operation.Avoid
There may be delay during due to FrameCallback interface or leakage is called, and the animation interim card producing, use to user and bring
Constant.
Exemplary, described obtain described current interpolation operation and be specifically as follows with the time interval of last time interpolation operation
After carrying out current interpolation operation, start the timer of configuration preset time period, upon the timer expiry, receive synchronizing signal
When, control FrameCallback interface to carry out the interpolation operation of preset times.
Described preset times pre-set according to described preset time period, such as when preset time period is 60 milliseconds,
Described preset times can be 3.That is, when described time interval is more than described preset time period, calling
The FrameCallback interface of Choreographer module carries out 3 number interpolation operations.Thus, described when described when the described time
When interval is more than described preset time period, the FrameCallback interface of Choreographer module is called to carry out preset times
Interpolation operation is specially：When described time interval is more than described preset time period, according to default preset time period and interpolation time
The corresponding relation of number determines the number of times into row interpolation；Call Choreographer module FrameCallback interface carry out pre-
If the interpolation of number of times.So can avoid due to FrameCallback interface leakage adjust etc. reason produce interpolation uneven or
Person's interim card problem.
Present invention also offers a kind of animation drawing system based on synchronizing signal, as shown in Fig. 2 it includes：
