shape画小圆点

<shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="oval"    android:useLevel="false">    <solid android:color="@color/while_01" />    <padding        android:bottom="1dp"        android:left="2dp"        android:right="2dp"        android:top="1dp" />    <solid android:color="@color/while_01" />    <stroke        android:width="1dp"        android:color="@android:color/white" />    <!--这里宽高要一样 -->    <size        android:width="15dp"        android:height="15dp" /></shape>
