Changing the indicator of the current current location in google map v2

map screenshot

In google map v1, we can change the current location indicator using overlay overlay, but I think map v2 is something else. Can someone suggest a way to replace the original indicator image?

Using My Location layer , you cannot change the symbolism (icon) of the current location.

As a workaround, you can implement this functionality by using Location Updates and drawing a location on a map.

For this, you can use this implementation of LocationListener , which draws the current location and accuracy:

 import android.graphics.Color; import android.location.Location; import android.location.LocationListener; import android.os.Bundle; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.model.BitmapDescriptor; import com.google.android.gms.maps.model.BitmapDescriptorFactory; import com.google.android.gms.maps.model.Circle; import com.google.android.gms.maps.model.CircleOptions; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.Marker; import com.google.android.gms.maps.model.MarkerOptions; public class MyLocationLayer implements LocationListener { private GoogleMap map; private BitmapDescriptor markerDescriptor; private boolean drawAccuracy = true; private int accuracyStrokeColor = Color.argb(255, 130, 182, 228); private int accuracyFillColor = Color.argb(100, 130, 182, 228); private Marker positionMarker; private Circle accuracyCircle; public MyLocationLayer(GoogleMap map, int markerResource) { this.map = map; markerDescriptor = BitmapDescriptorFactory.fromResource(markerResource); } public void setDrawAccuracy(boolean drawAccuracy) { this.drawAccuracy = drawAccuracy; } public void setAccuracyStrokeColor(int color) { this.accuracyStrokeColor = color; } public void setAccuracyFillColor(int color) { this.accuracyFillColor = color; } @Override public void onLocationChanged(Location location) { double latitude = location.getLatitude(); double longitude = location.getLongitude(); float accuracy = location.getAccuracy(); if (positionMarker != null) { positionMarker.remove(); } final MarkerOptions positionMarkerOptions = new MarkerOptions() .position(new LatLng(latitude, longitude)) .icon(markerDescriptor) .anchor(0.5f, 0.5f); positionMarker = map.addMarker(positionMarkerOptions); if (accuracyCircle != null) { accuracyCircle.remove(); } if (drawAccuracy) { final CircleOptions accuracyCircleOptions = new CircleOptions() .center(new LatLng(latitude, longitude)) .radius(accuracy) .fillColor(accuracyFillColor) .strokeColor(accuracyStrokeColor) .strokeWidth(2.0f); accuracyCircle = map.addCircle(accuracyCircleOptions); } } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderEnabled(String provider) { } @Override public void onProviderDisabled(String provider) { } }

Improvements to be completed

You can rotate the marker depending on the direction of movement using public MarkerOptions rotation (float rotation) https://developers.google.com/android/reference/com/google/android/gms/maps/model/MarkerOptions.html#rotation ( float)
