java - Android OnLongClickListener not firing on MapView

Question

I just registered an OnLongClickListener on my my MapView on an Android app I'm currently writing. For some reason however the onLongClick event doesn't fire.

Here's what I've written so far:

public class FriendMapActivity extends MapActivity implements OnLongClickListener {
    private static final int CENTER_MAP = Menu.FIRST;
    private MapView mapView;
    private MapController mapController;
    //...
    private boolean doCenterMap = true;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.friendmapview);
        this.mapView = (MapView) findViewById(R.id.map_view);
        this.mapController = mapView.getController();

        mapView.setBuiltInZoomControls(true);
        mapView.displayZoomControls(true);
        mapView.setLongClickable(true);
        mapView.setOnLongClickListener(new OnLongClickListener() {
            public boolean onLongClick(View v) {
                //NEVER FIRES!!
                return false;
            }
        });

        //...
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        switch (keyCode) {
        case KeyEvent.KEYCODE_3:
            mapController.zoomIn();
            break;
        case KeyEvent.KEYCODE_1:
            mapController.zoomOut();
            break;
        }
        return super.onKeyDown(keyCode, event);
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        int actionType = ev.getAction();
        switch (actionType) {
        case MotionEvent.ACTION_MOVE:
            doCenterMap = false;
            break;
        }

        return super.dispatchTouchEvent(ev);
    }

        ...
}

May overlays which I'm adding cause the problem?? Any suggestions?

I ran into the same problem and there is a simple solution to your problem actually; it's because you're using the wrong type of listener.

You should use the OnMapLongClickListener() object from the OnMapLongClickListener interface.

Hopefully everything should work properly :) Please tell me if it works.
