Tabhost at the bottom of Android implementation

First, the layout file is shown as follows: Use Android: layout_alignparentbottom = "true" to display the bottom

 1 <?xml version="1.0" encoding="utf-8"?> 2 <TabHost xmlns:android="http://schemas.android.com/apk/res/android" 3      android:id="@android:id/tabhost"  4      android:orientation="vertical" 5     android:layout_width="fill_parent" 6     android:layout_height="fill_parent"> 7     <RelativeLayout 8         android:background="@drawable/g" 9         android:layout_width="fill_parent"10         android:layout_height="fill_parent">11     <TabWidget android:id="@android:id/tabs"12         android:layout_width="fill_parent"13         android:layout_height="wrap_content"14         android:layout_alignParentBottom="true">15     </TabWidget>16     <FrameLayout android:id="@android:id/tabcontent"17         android:layout_width="fill_parent"18         android:layout_height="fill_parent">19         <RelativeLayout android:id="@+id/tabFirst"20             android:layout_width="fill_parent"21             android:layout_height="fill_parent"22             android:orientation="vertical">23         <AnalogClock24             android:id="@+id/widget31"25             android:layout_width="wrap_content"26             android:layout_height="wrap_content"27             android:layout_centerInParent="true">28         </AnalogClock>29         </RelativeLayout>>30         <RelativeLayout android:id="@+id/tabSecond"31             android:layout_width="fill_parent"32             android:layout_height="fill_parent"33             android:orientation="vertical">34             <DigitalClock35                 android:layout_centerInParent="true"36                 android:layout_width="wrap_content"37                 android:layout_height="wrap_content">38             </DigitalClock>39         </RelativeLayout>40     </FrameLayout>41     </RelativeLayout>42 </TabHost>

The following is the main program code, which is detailed in Annotation writing. I will not explain it more here.
