Question

I simply want a mapview to recognize a click, in order to call another activity.

Until now, i tried the regular “onClick”,that always worked for me in regular Views, followed by overriding “onTouchEvent” and last but not least using an onClickListener.

I out all three ways into the following code. Any help is highly appreciated.

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;

public class HelloMapView extends MapActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
     final MapView map;
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        map = (MapView) findViewById(R.id.mapview);

        map.setOnClickListener(new MapView.OnClickListener() {
         public void onClick(View v){
          System.out.println("I listened!");
         }  
        });
    }
    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent arg0) {

     System.out.println("onTouchEvent happened!");        
        super.onTouchEvent(arg0);

        return super.onTouchEvent(arg0);
        }

    public void onClick(){
     System.out.println("onClick entered!");
    }    
}

Add an Overlay in your map view and handle the OnTouchEvent. Try something like this:

public class MyMapActivity extends MapActivity {

class MapOverlay extends com.google.android.maps.Overlay
{       
    @Override
    public boolean onTouchEvent(MotionEvent e, MapView mapView) 
    {   
        if (e.getAction() == MotionEvent.ACTION_UP) {                
            GeoPoint p = mapView.getProjection().fromPixels(
                (int) e.getX(),
                (int) e.getY());
            MyMapActivity this.startActivityForResult(intent, requestCode);
        }                            
        return false;
    }        
}

      // MyMapActivity methods
      @Override
      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mapView = (MapView) findViewById(R.id.mapview);

        MapOverlay mapOverlay = new MapOverlay();
        List<Overlay> listOfOverlays = mapView.getOverlays();
        listOfOverlays.clear();
        listOfOverlays.add(mapOverlay);
  }
}
