public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback, OnMapClickListener {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        mMap.setOnMapClickListener(this);
    }

    @Override
    public void onMapClick(LatLng point) {
        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(point);
        markerOptions.title("新标记");
        mMap.addMarker(markerOptions);
    }
}
