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"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent">    <RadioGroup        android:layout_width="match_parent"        android:layout_below="@+id/icon"        android:layout_height="40dp"        android:layout_marginBottom="15dp"        android:layout_marginLeft="20dp"        android:layout_marginRight="20dp"        android:orientation="horizontal"        android:background="@drawable/cd_rg_list"        >        <RadioButton            android:id="@+id/rb_dai"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:button="@null"            android:checked="true"            android:gravity="center"            android:background="@drawable/cd_left_list_selector"            android:textColor="@drawable/list_text_selector"            android:text="财富查询"            />        <RadioButton            android:id="@+id/rb_yi"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:button="@null"            android:gravity="center"            android:background="@drawable/cd_center_list_selector"            android:textColor="@drawable/list_text_selector"            android:text="近期收益"            />        <RadioButton            android:id="@+id/rb_er"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:button="@null"            android:gravity="center"            android:background="@drawable/cd_right_list_selector"            android:textColor="@drawable/list_text_selector"            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>

涉及到一些drawable

差不多就是这样，记录下，用的地方很多，方便下次再用！
