sure !
public class MyMapActivity extends MapActivity {
private OverlayController mOverlayController;
private MapController mapController;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
MapView mapView = new MapView(this);
mapController = mapView.getController();
mOverlayController = mapView.createOverlayController();
mapController.zoomTo(9);
setContentView(mapView);
}
}
here is the tab layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabHost android:id="@+id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="65px" />
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="200px"
android:paddingTop="65px" >
<LinearLayout android:id="@+id/content1"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff99ccff" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="some text here" />
</LinearLayout>
</FrameLayout>
</TabHost>
</LinearLayout>
and the onCreate in the TabsActivity
@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.two_tabs);
TabHost tabs = (TabHost)this.findViewById(R.id.tabs);
tabs.setup();
TabHost.TabSpec tab1= tabs.newTabSpec("tab1");
tab1.setContent(R.id.content1);
tab1.setIndicator("tab1",
getResources().getDrawable(R.drawable.drawable1));
tabs.addTab(buddies);
TabHost.TabSpec tab2= tabs.newTabSpec("tab2");
tab2= map.setContent(new Intent(this, MyMapActivity.class));
tab2.setIndicator("tab2",
getResources().getDrawable(R.drawable.drawable2));
tabs.addTab(map);
tabs.setCurrentTab(0);
}
thank you !
