How to attach a flexible marker on map something like Uber and Lyft ?
am using Google maps v2.
Basically, i want to display a marker on map while the position of the marker is changed upon moving the map.

Ok i solved my problem.
first : add an imageview to the same layout and position equal to center.
second: to get the coordinate of the center of the map use the following approach
1- get viewgroup ( FrameLayout ) in my case where the map fragment is located.
FrameLayout myContainer = (FrameLayout) findViewById(R.id.content_frame);
int mapHeight = myContainer.getHeight();
int mapWidth = myContainer.getWidth();

2- use setOnCameraChangeListener and on camera change get the coordinates:
LatLng center = mMap.getCameraPosition().target;
