设置边框圆角可以在drawable-mdpi目录里定义一个xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#000000" />
<corners android:topLeftRadius="10dp"
android:topRightRadius="10dp"
android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"/>
</shape>
<corners android:radius="5dp" />
android:background="@drawable/corners_bg"
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#FFFFFF">
<RelativeLayout android:id="@+id/login_div"
android:layout_width="fill_parent" android:layout_height="150dip"
android:padding="15dip" android:layout_margin="15dip"
android:background="@drawable/corners_bg">
</RelativeLayout>
</LinearLayout>
