让android系统中任意一个view变成进度条

1.效果

      

2.进度条背景drawable文件

  结束后可以恢复原背景.

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
 3     <item android:id="@+id/background">
 4         <shape
 5             android:layout_width="wrap_content"
 6             android:shape="rectangle">
 7             <corners android:radius="12dp" />
 8             <stroke android:color="#dcdcdc" android:width="1px" ></stroke>
 9             <solid android:color="#f7f7f7" />
10         </shape>
11     </item>
12     <item android:id="@+id/progressing"
13         android:top="2px"
14         android:right="2px"
15         android:bottom="2px"
16         android:left="2px">
17         <clip
18             android:clipOrientation="horizontal"
19             android:gravity="left" android:shape="rectangle">
20             <shape>
21                 <corners android:radius="12dp" />
22                 <solid android:color="#fee2cd" />
23             </shape>
24         </clip>
25     </item>
26 </layer-list>

3.更新进度

  在进度更新代码里 计算出进度值pro,然后更新. 

1    LayerDrawable ld = (LayerDrawable) view.getBackground();
2     ClipDrawable clipDrawable = (ClipDrawable) ld.findDrawableByLayerId(R.id.progressing);
3     clipDrawable.setLevel(100 * pro);
