创建需要的5个Activity
布局文件main.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"

创建drawable文件夹，添加home_btn_bg.xml
<?xml version="1.0" encoding="UTF-8"?>
<selector

<item android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/home_btn_bg_d" />
<item android:drawable="@drawable/transparent" />
</selector>
在values文件夹下添加dimens.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <dimen name="bottom_tab_padding_drawable">2.0dip</dimen> <dimen name="bottom_tab_padding_up">5.0dip</dimen> <dimen name="bottom_tab_font_size">10.0dip</dimen> </resources>
在values文件夹下添加drawables.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <item type="drawable" name="transparent">#00000000</item> </resources>
strings.xml
<resources>
<string name="app_name">TestBottomBar</string>

styles.xml
<resources>
<style name="AppTheme" parent="android:Theme.Light" />
<style name="main_tab_bottom">
