Take a gray Button with a rounded border as an example:


1. Create a ShapeDrawable as the background and create a button_rounded_background.xml file in the drawable directory:

<shape xmlns:android = "http://schemas.android.com/apk/res/android"    android:shape= "rectangle" >    <solid android:color= "#AAAAAA" />    <corners android:radius= "15dp" /></shape>

See the name, in addition to the <solid/>, <corners/> label, <shape/> also supports a lot of different functional labels, for more information, please go to the Android official documentation: http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
2. Apply ShapeDrawablemain. xml to the Button:

<RelativeLayout xmlns:android = "http://schemas.android.com/apk/res/android"    android:layout_width= "fill_parent"    android:layout_height= "fill_parent"    android:gravity= "center" >    <Button        android:id ="@+id/button"        android:layout_width ="wrap_content"        android:layout_height ="wrap_content"        android:background ="@drawable/button_rounded_background"        android:padding ="10dp"        android:text ="@string/hello"        android:textColor ="#000000" /></RelativeLayout>

Now a Button with a rounded border has been built.
ShapeDrawable can be used not only in the Button, but also with all controls with background, such as items in ListView.
