试试这个：
ring.xml
<?xml version="1.0" encoding="utf-8"?><shapexmlns:android="http://schemas.android.com/apk/res/android"android:shape="ring"android:innerRadius="50dp"android:thickness="2dp"android:useLevel="false"><stroke android:width="2dp" android:color="#ababf2"/><solid android:color="@android:color/transparent" /></shape>
您的xml
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" ><RelativeLayout android:id="@+id/rel" android:layout_width="120dp" android:layout_height="120dp" android:layout_centerInParent="true" android:background="@drawable/ring" > </RelativeLayout></RelativeLayout>
