RadioButton 设置selector熟悉实现Tab功能

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_enabled="true" android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/tab_normal"/>    <item android:state_enabled="true" android:state_pressed="true" android:drawable="@drawable/select"/>    <item android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/select"/>    <item android:drawable="@drawable/tab_normal"/></selector>

tab_normal为没选择的背景，tab_select为选择时的背景
