xml version="1.0" encoding="utf-8"?>
selector xmlns : android = "http://schemas.android.com/apk/res/
In the development process, often encounter such a scene, click the button, the background color changes: In drawable, define Xxx.xml (selector)selectorxmlns:android= "Http://schemas.android.com/apk/res/android"> Itemandroid:drawable= "#ee0000"android:state_focused= "true"/> Itemandroid:drawable= "#ee0000"android:state_selected= "true"/> Itemandroid:drawable= "#ee0000"android:state_pressed= "true"/
