画圆环，外边的边界宽度大一点即可：

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

    android:shape="oval"

    android:useLevel="false" >

    <solid android:color="@color/deliveryTop" />

    <stroke

        android:width="3dp"  //值越大，里面圆越小

        android:color="@color/deliveryBottom" />

    <size

        android:height="15dp"

        android:width="15dp" />

</shape>

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="@color/dark_blue" />

    <stroke

        android:width="2px"

        android:color="#ffffff" />

    <corners

        android:bottomLeftRadius="5dp"

        android:bottomRightRadius="5dp"

        android:topLeftRadius="5dp"

        android:topRightRadius="5dp" />

</shape>
