推荐答案

你缺乏了几个标签。这里有一个新的样本：

You're lacking a couple of tags. Here's a new sample:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
    <solid android:color="#ffffff"/>    

    <stroke android:width="3dp"
            android:color="#ff000000"/>

    <padding android:left="1dp"
             android:top="1dp"
             android:right="1dp"
             android:bottom="1dp"/> 

    <corners android:radius="30px"/> 
</shape>

另外，你是否知道 RoundRectShape 的？

Also, are you aware of RoundRectShape?
