The Foursquare app for Android is open source. Je crois que ce que vous cherchez est leur main_activity.xml:
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<!-- Background color should be the last value in the selected tab gradient. -->
<LinearLayout
android:id="@+id/tabBackground"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dip"
android:background="#4d4d4d">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<!-- A paddingTop of zero will remove the strip below the tabs. -->
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="5dip" />
</LinearLayout>
</TabHost>
