LinearLayout custom highlighting method for Android layout

This article illustrates the LinearLayout approach to custom highlighting of Android layouts. To share with you for your reference, as follows:

First create the file linearlayout_background.xml

res/drawable/linearlayout_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selectorxmlns:android="http://schemas.android.com/apk/res/android">
  <itemandroid:state_pressed="true" android:drawable="@drawable/button_pressed"/>
  <itemandroid:state_focused="true" android:drawable="@drawable/button_pressed"/> 
   <itemandroid:drawable="@drawable/button_normal"/>
</selector>

The second is in the corresponding xml layout file

<LinearLayout
  android:layout_height="wrap_content"
  android:layout_width="wrap_content"
  android:clickable="true"<!-- This is a must, otherwise there will be no highlighting, which is different from automatic button . textview And other controls. -->
    android:background="@drawable/linearlayout_background"> 
<Button ....../>
<TextView ...../>
</LinearLayout>
