android背景圓角

android背景圓角的實現
1.創建一個xml文件，命名爲circle_corner,放置到drawable目錄下，內容以下：

<? 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.在須要圓角背景的元件上設置背景爲circle_corner

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