                    marker = BitmapDescriptorFactory.fromResource(R.drawable.marker);
                    pointaa = BitmapDescriptorFactory.fromResource(R.drawable.pointaa);
                    pointb = BitmapDescriptorFactory.fromResource(R.drawable.pointb);

                public void onMapClick(final LatLng center) {
                    clickcounter=clickcounter+1;
    if (clickcounter==1){
        if (marker!=null){
            Toast.makeText(getApplicationContext(),"1",Toast.LENGTH_SHORT).show();
            marker = BitmapDescriptorFactory.fromResource(R.drawable.marker);

        }



    }if (clickcounter==2){
                        Toast.makeText(getApplicationContext(),"2",Toast.LENGTH_SHORT).show();
                        pointaa = BitmapDescriptorFactory.fromResource(R.drawable.pointaa);
                        addPoint(center);


                    }if (clickcounter==3){
                        Toast.makeText(getApplicationContext(),"3",Toast.LENGTH_SHORT).show();
                        pointb = BitmapDescriptorFactory.fromResource(R.drawable.pointb);
                        addPoint(center);

                    }

                }
            });


      private Marker drawMarker(final LatLng center) {
            return mMap.addMarker(
                    new MarkerOptions().position(center).flat(true).anchor(0.5f, 0.5f).icon(pointb).icon(pointaa).icon(marker));

Use Below code 

  mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {

                marker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE));

                return true;
            }

You can change the marker icon as below.

Marker marker = new MarkerOptions().position(center).flat(true).anchor(0.5f, 0.5f);
BitmapDescriptor descriptor = BitmapDescriptorFactory.fromResource(R.drawable.marker); 
   // Changing marker icon
marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));
