二 app端的实现是主要通过AnimationUtils来实现具体属性的变化通过invilate来驱动 wms来进行更新。这个流程是在app进程完成
这里不是我分析的重点 直接来看下系统动画里面的本地动画app启动动画这个流程是在系统进程完成 这里分成三个部分的流程 动画的触发动画的加载动画的启动动画的关闭。
这里大概写下流程下面有具体的调用堆栈 1 触发 ams.attachapplicaton---activitystack.minimalresumeactivitylocked---rootwindowcontainner--displaycontent ---wms.requestTraversal--mService.mAnimationHandler.post(mPerformSurfacePlacement);(post 一个runnable消息给wms)
2 启动 ---rootwindowcontainer---performsurfaceplacementnotrace------apptransitioncontroller.applyanimations--- ---windowcontainer.applyanimationunchecked -----surfaceanimator.startanimation--(创建leash然后Transaction.reparent(surface,leash)) ---localanimationadapter(animationadapter的父类)---surfaceanimationrunner.startanimation--mChoreographer.postFramecallback 3 关闭 windowcontainer循环完后调用wms的onAnimationfinished。
