How to handle long press on a map, using OSMDroid / OSMBonusPack in Android?

问题

I am trying to create a simple application with maps, on Android. I am using OSMDroid's MapView to render the basic OpenStreet Map mapview.

I have a custom MapActivity that implements the MapEventsReceiver interface (from OSMBonusPack). In my activity's onCreate(), I create a MapEventsOverlay, I add it to the mapView.

The problem is, longPressHelper() and singleTapUpHelper() are never called. See my code below.

public abstract class CustomMap extends BaseActivity implements MapEventsReceiver{
//variable declarations follow
private MapView mMapView;

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(load);
setContentView(R.layout.activity_map_main_screen);

mMapView = (MapView) findViewById(R.id.mapmainscreen);
mMapView.setBuiltInZoomControls(true);
mMapView.setClickable(true);

MapEventsOverlay evOverlay = new MapEventsOverlay(this, this);
mMapView.getOverlays.add(evOverlay);
mMapView.invalidate();

//tile source / tile provider are set by another method elsewhere

//somewhere in my code (same class file) I also have this:

@Override
public boolean longPressHelper(IGeoPoint arg0) {
Log.d(TAG, "longPressHelper was called");//this is never called
return true;
}

@Override
public boolean singleTapUpHelper(IGeoPoint arg0) {
Log.d(TAG, "singleTapUpHelper was called");//this is never called
return true;
}
}      
}

Please note that I have tried the suggested solution here OSMDroid: Adding a marker when user taps on map

Any help is much appreciated.

回答1:

The code you provided is correct. So the issue is somewhere else...

Could you specify versions used: Android SDK, osmdroid, and OSMBonusPack?

Maybe something in the layout? You can check by comparing with OSMBonusPackTuto activity_main.xml layout.
