我为这个LinearLayout设置了一个xml drawable,我想为它添加另一个。这是第一个xml drawable:

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

在这一步,我想在这个LinearLayout周围添加一个边框,我创建了另一个可绘制的布局。这是代码:

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

    <solid android:color="#FFFFFF"/>
    <stroke android:width="3dip" android:color="#B1BCBE" />
    <corners android:radius="10dip"/>

You can not apply two drawable to a layout but you can achieve your requirement using single drawable only.

您不能将两个drawable应用于布局,但只能使用单个drawable来实现您的要求。

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

<item android:drawable="@color/blue" android:state_pressed="true"/>
<item android:drawable="@color/blue" android:state_selected="true"/>
<item android:drawable="@drawable/name_of_your_second_drawable"/>

</selector>
