动画描述：动画与底部菜单一样出现和消失

制作过程：

1. 创建两个动画文件

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>

2.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>

3. 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();
