Okay folks, I seem to have found a solution thanks to the helpful
people who posted above.
Here it is...
1. Create a new class called TabbedMapActivity
2. Paste this in the new class:
import android.app.Activity;
import android.app.LocalActivityManager;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
/**
* A screen that contains and runs multiple embedded activities.
* AND NOW... allows you to contain a MapView
* Edited by Miles
*/
public class TabbedMapActivity extends MapActivity {
private static final String STATES_KEY = "android:states";
/**
* This field should be made private, so it is hidden from the
SDK.
* [EMAIL PROTECTED]
*/
protected LocalActivityManager mLocalActivityManager;
public TabbedMapActivity() {
this(true);
}
public TabbedMapActivity(boolean singleActivityMode) {
mLocalActivityManager = new LocalActivityManager(this,
singleActivityMode);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle states = savedInstanceState != null
? (Bundle) savedInstanceState.getBundle(STATES_KEY) :
null;
mLocalActivityManager.dispatchCreate(states);
}
@Override
protected void onResume() {
super.onResume();
mLocalActivityManager.dispatchResume();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
Bundle state = mLocalActivityManager.saveInstanceState();
if (state != null) {
outState.putBundle(STATES_KEY, state);
}
}
@Override
protected void onPause() {
super.onPause();
mLocalActivityManager.dispatchPause(isFinishing());
}
@Override
protected void onStop() {
super.onStop();
mLocalActivityManager.dispatchStop();
}
@Override
protected void onDestroy() {
super.onDestroy();
mLocalActivityManager.dispatchDestroy(isFinishing());
}
public Activity getCurrentActivity() {
return mLocalActivityManager.getCurrentActivity();
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
3. In the Activity which contains both the TabHost and your MapView
change the "extends" to extend your new class, e.g:
extends TabbedMapActivity
4. When you call setup() on your TabHost, change it to read:
tabs.setup(mLocalActivityManager);
(This references the LocalActivityManager we just created in the
TabbedMapActivity we defined in step 2)
5. Rebuild and run!
This works for me, so now I can have a MapView and a TabHost which
includes Intents as content to each tab in the TabHost.
Hope this helps someone and again thanks for those who helped me with
this!
