一、xml设置
<RadioGroup
android:id="@+id/rg_tab"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="3" >
<RadioButton
android:id="@+id/rb_firstpage"
style="@style/main_tab_bottom"
android:checked="true"
android:drawableTop="@drawable/bar_home_selector"
android:drawablePadding="3dp"
android:paddingTop=“10dp"
android:paddingBottom=“5dp"
android:text="首页"
/>
<RadioButton
android:id="@+id/rb_service"
android:drawableTop="@drawable/bar_service_selector"
style="@style/main_tab_bottom"
android:drawablePadding="3dp"
android:paddingTop="10dp"
android:paddingBottom="5dp"
android:text="服务"
/>
<RadioButton
android:id="@+id/rb_aboutus"
android:drawableTop="@drawable/bar_setting_selector"
style="@style/main_tab_bottom"
android:drawablePadding="3dp"
android:paddingTop=“10dp"
android:paddingBottom="5dp"
android:text="个人"
/>
</RadioGroup>
二、bar_home_selector文件的编写，其余类同，放在res/drawable，自己创建
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/dh_lan_1_03" android:state_pressed="true"></item>
<item android:drawable="@drawable/dh_lan_1_03" android:state_checked="true"></item>
<item android:drawable="@drawable/dh_hui_1_03" android:state_checked="false"></item>
</selector>
三、main_tab_bottom文件的编写，放在了res/values/styles中
<style name="main_tab_bottom">
<!-- <item name="android:drawablePadding">-1dp</item> -->
<item name="android:textColor">@color/bottom_text_color</item>
<item name="android:textSize">11dp</item>
<item name="android:gravity">center</item>
<item name="android:background">@drawable/transparent</item>
<item name="android:layout_width">0dp</item>
<item name="android:layout_weight">1.0</item>
<item name="android:layout_height">fill_parent</item>
<!-- 去按钮立体效果 -->
<item name="android:button">@null</item>
<item name="android:singleLine">true</item>
</style>
