简单好用的tab切换页面

闲来无事，总结下一个经常用到的tab切换的功能。

先上图：



这个是利用的RadioGroup和radiobutton实现点击切换tab功能，废话不说了，上代码吧！

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<RadioGroup

<RadioButton

<RadioButton

<RadioButton

android:text="推荐历史"
/>
</RadioGroup>
<RelativeLayout
android:id="@+id/rl_main"
android:layout_width="match_parent"
android:layout_height="match_parent"></RelativeLayout>
</RelativeLayout>
