android布局的圆角边框

shape_corner.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<solid android:color="#99CCFF" />
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />

</shape>activity_main.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"

不用写 android:radius="20dp".......
