上面的view类利用postInvalidate来不断刷新自身，刷新时调用ondraw重绘，重绘时根据情况绘制不同的图片到屏幕中央，形成动画（类似逐帧动画）

在activity中放入上述view：

<FrameLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<ImageView 
android:src="@drawable/gmfou" 
android:layout_height="fill_parent" 
android:layout_width="fill_parent" 
android:scaleType="fitXY"
android:id="@+id/iv_fo"/>
       
<zy.qiufo.QiuQianAnimationView
   android:id="@+id/vw_animationPic"
   android:layout_height="wrap_content"
   android:layout_width="wrap_content" 
   />  

</FrameLayout>
