Android -- Dialog动画

window_in.xml

<?xml version="1.0" encoding="utf-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android" >  
<translate  
        android:duration="500"  
        android:fromXDelta="0"  
        android:fromYDelta="1000"  
        android:toXDelta="0"  
        android:toYDelta="0" />  
</set>

window_out.xml

<?xml version="1.0" encoding="utf-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android" >  
<translate  
        android:duration="500"  
        android:fromXDelta="0"  
        android:fromYDelta="0"  
        android:toXDelta="0"  
        android:toYDelta="1000" />  
</set>

将动画配置到style中

<style name="main_menu_animstyle">  
       <item name="android:windowEnterAnimation">@anim/settingswindow_in_anim</item>  
       <item name="android:windowExitAnimation">@anim/settingswindow_out_anim</item>  
   </style>

将动画应用于Dialog

Window window = dialog.getWindow();  
//设置显示动画  
window.setWindowAnimations(R.style.main_menu_animstyle);  
WindowManager.LayoutParams wl = window.getAttributes();  
wl.x = 0;  
wl.y = getWindowManager().getDefaultDisplay().getHeight();  
//设置显示位置  
dialog.onWindowAttributesChanged(wl);//设置点击外围解散  
dialog.setCanceledOnTouchOutside(true);  
dialog.show();
