android 画一个矩形shape背景

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid
        android:color="@color/red" />
    <!-- 边缘线条颜色 -->
    <stroke
        android:width="1dp"
        android:color="@color/red" />
    <!-- 圆角的幅度 -->
    <corners
        android:topLeftRadius="@dimen/common20dp"
        android:topRightRadius="@dimen/common20dp"
        android:bottomLeftRadius="@dimen/common20dp"
        android:bottomRightRadius="5dip" />
</shape>
