Answer 1

您错过了android:color

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#F0FFFFFF" />

    <stroke
        android:width="1dp"
        android:color="#A00080FF" />

    <padding
        android:bottom="1dp"
        android:left="5dp"
        android:right="5dp"
        android:top="0dp" />
</shape>

    <solid android:color="#F0FFFFFF" />

    <stroke

        color="#A00080FF" />

    <padding

Answer 3

在第一行添加此行，并在颜色属性

之前添加android:

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

您的代码应该是这样的：

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

    <solid android:color="#F0FFFFFF" />

    <stroke
        android:width="1dp"
        android:color="#A00080FF"/>

    <padding
        android:bottom="1dp"
        android:left="5dp"
        android:right="5dp"
        android:top="0dp" />
</shape>
