Android 用Animation-list实现逐帧动画

<?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>
      <item android:drawable="@drawable/icon2" android:duration="150"></item>
      <item android:drawable="@drawable/icon3" android:duration="150"></item>

      <item android:drawable="@drawable/icon5" android:duration="150"></item>
      <item android:drawable="@drawable/icon6" android:duration="150"></item>
</animation-list>
