First say the layout file, as follows: Using android:layout_alignparentbottom= "true" to achieve the bottom display

<?XML version= "1.0" encoding= "Utf-8"?><Tabhostxmlns:android= "Http://schemas.android.com/apk/res/android"Android:id= "@android: Id/tabhost"android:orientation= "vertical"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent">    <RelativelayoutAndroid:background= "@drawable/g"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent">    <TabwidgetAndroid:id= "@android: Id/tabs"Android:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:layout_alignparentbottom= "true">    </Tabwidget>    <FramelayoutAndroid:id= "@android: Id/tabcontent"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent">        <RelativelayoutAndroid:id= "@+id/tabfirst"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical">        <AnalogClockAndroid:id= "@+id/widget31"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_centerinparent= "true">        </AnalogClock>        </Relativelayout>><RelativelayoutAndroid:id= "@+id/tabsecond"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical">            <DigitalClockandroid:layout_centerinparent= "true"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content">            </DigitalClock>        </Relativelayout>    </Framelayout>    </Relativelayout></Tabhost>

Here is the main program code, comments written in more detail, there is no more explanation
