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
