android背景圆角

android背景圆角的实现
1.创建一个xml文件，命名为circle_corner,放置到drawable目录下，内容以下：

<? xml version ="1.0" encoding ="utf-8" ?>
< shape xmlns:android = "http://schemas.android.com/apk/res/android" >
   < gradient android:endColor ="@android:color/transparent"     android:startColor ="#000000" android:gradientRadius ="60"     android:type ="radial" />
         < corners android:radius ="10px" />
</ shape >

2.在须要圆角背景的元件上设置背景为circle_corner

< TextView android:text ="abc" android:background ="@drawable/circle_corner"     android:layout_width ="wrap_content" android:layout_height ="wrap_content"
>
