Google Mapを開くためのアンドロイドスタジオでMapActivityを作成しましたが正常に動作しています。しかし、今では、場所が選択されたときに(地図をタップして)位置の座標を取得したいので、どうすればいいですか?あなたのonMapReady
インサイドGoogleマップから位置の座標を取得する方法

public class Map extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.

@Override
public void onMapReady(GoogleMap googleMap) {
//GPSTracker gps = new GPSTracker(MapsActivity.this);
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-33.868664, 151.183194);
mMap.addMarker(new MarkerOptions().position(sydney).title("Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
mMap.animateCamera(CameraUpdateFactory.zoomTo(17.0f));
