Android Dev Notes - 18 - 关于为Activity的进入和退出绑定动画

在Activity中提供了设定活动进出对话的方法

 

先看一下源代码~

/** * Call immediately after one of the flavors of {@link #startActivity(Intent)} * or {@link #finish} to specify an explicit transition animation to * perform next. * @param enterAnim A resource ID of the animation resource to use for * the incoming activity. Use 0 for no animation. * @param exitAnim A resource ID of the animation resource to use for * the outgoing activity. Use 0 for no animation. */ public void overridePendingTransition(int enterAnim, int exitAnim) { try { ActivityManagerNative.getDefault().overridePendingTransition( mToken, getPackageName(), enterAnim, exitAnim); } catch (RemoteException e) { } }

 

意思就是说：调用这个方法的地方需要紧接着以下函数

1. startActivity(Intent)

2. finish()

 

int enterAnim，为将要进入的活动设置动画

int exitAnim，为将要退出的活动设置动画

 

 

如何在程序中使用这个方法

Method m = Activity.class.getDeclaredMethod(
                    "overridePendingTransition", Integer.TYPE, Integer.TYPE);
m.invoke(this, R.anim.back_enter, R.anim.back_exit);
