Android利用animation-list实现帧动画

<?xml version="1.0" encoding="utf-8"?> 
<!--  
  根标签为animation-list，其中oneshot代表着是否只展示一遍，设置为false会不停的循环播放动画 
  根标签下，通过item标签对动画中的每一个图片进行声明 
  android:duration 表示展示所用的该图片的时间长度 
 --> 
<animation-list 
 xmlns:android="http://schemas.android.com/apk/res/android" 
 android:oneshot="true"

  <item android:drawable="@drawable/icon1" android:duration="150"></item>
