Add Marker on Android Google Map via touch or tap

Question

I want to develop a Map Application using Google Map on Android. Now, I want to add marker on the map via Touch or Tap on the Map. How do I apply touch event to drop the marker on the map?

Answer 1

Try using new Google Map API v2.

It's easy to use and you can add a marker on tap like this:

map.setOnMapClickListener(new GoogleMap.OnMapClickListener() {     @Override     public void onMapClick(LatLng point) {         allPoints.add(point);         map.clear();         map.addMarker(new MarkerOptions().position(point));     } }); 

or in Kotlin:

map.setOnMapClickListener {     allPoints.add(it)     map.clear()     map.addMarker(MarkerOptions().position(it)) } 

Note that you might want to remember all your added points in a list (allPoints), so you can re-draw or remove them later. An even better approach to remember the points would be to remember a Marker object for each of them - you can get the Marker object as a result from the addMarker function, it has a remove() function that easily removes the marker from the map.

Answer 2

The technique which i used is:

googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {     @Override     public void onMapClick(LatLng point) {                    MarkerOptions marker = new MarkerOptions().position(new LatLng(point.latitude, point.longitude)).title("New Marker");         googleMap.addMarker(marker);         System.out.println(point.latitude+"---"+ point.longitude);       } }); 

Hope it helps!!!
