点击LinearLayout使用selector改变TextView字体颜色

 <LinearLayout
     android:clickable="true"
     android:focusable="true">
     <TextView
         android:duplicateParentState="true"/>
         android:textColor="@drawable/selector_setting_txt"
 LinearLayout>

 xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:state_pressed="true" android:color="@color/white">item>
     <item android:color="@color/txt_title">item>
 selector>

在父控件中添加android:clickable=“true” android:focusable=“true”，而在子控件中添加android:duplicateParentState=“true”子控件就能获得父控件的点击事件
