我有这个应用程序，我必须在其中放置一个品脱我的地图并获取我刚刚按下的大头针的纬度和经度，但是当我想单击地图时，应用程序无法识别水龙头，无论如何，这是我的代码：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
        GoogleMap.OnMapClickListener,
        View.OnClickListener,
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener 

GoogleMap mMap;
Double latitud, longitud;
Marker marker;
Button buttonAgregarUbicacion;
protected GoogleApiClient mGoogleApiClient;
protected Location mLastLocation;



@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);

    LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    checkGpsEnable(locationManager);
    buildGoogleApiClient();



    buttonAgregarUbicacion = (Button) findViewById(R.id.button_agregar_ubicacion);

    buttonAgregarUbicacion.setOnClickListener(this);




protected synchronized void buildGoogleApiClient() 
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();





private void checkGpsEnable(LocationManager locationManager) 
    if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) &&
            !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) 
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setMessage("Al parecer no tienes el GPS activado, para mejorar la experiencia enciéndolo.")
                .setCancelable(false)
                .setPositiveButton("Activar GPS",
                        new DialogInterface.OnClickListener() 
                            public void onClick(DialogInterface dialog, int id) 
                                Intent callGPSSettingIntent = new Intent(
                                        Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                                startActivity(callGPSSettingIntent);
                            
                        );
        alertDialogBuilder.setNegativeButton("Cancelar",
                new DialogInterface.OnClickListener() 
                    public void onClick(DialogInterface dialog, int id) 
                        dialog.cancel();
                        finish();
                    
                );
        AlertDialog alert = alertDialogBuilder.create();
        alert.show();
    




@Override
public void onMapReady(GoogleMap googleMap) 
    mMap = googleMap;
    mMap.getUiSettings().setMyLocationButtonEnabled(true);
    mMap.setMyLocationEnabled(true);

    if (mLastLocation != null) 
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(
                new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude()), 200));

        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude()))
                .zoom(17)
                .build();
        mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

    






@Override
public void onClick(View view) 
    switch (view.getId()) 
        case R.id.button_agregar_ubicacion:

            if (latitud == null) 
                Toast.makeText(MapsActivity.this, "Pon un pin en el mapa", Toast.LENGTH_SHORT).show();
             else 

                Intent intent = new Intent(this, CreateReportActivity.class);
                intent.putExtra("latitud", latitud);
                intent.putExtra("longitud", longitud);
                startActivity(intent);
                finish();

            

            break;
    



@Override
public void onConnected( Bundle connectionHint) 
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    onMapReady(mMap);



@Override
public void onConnectionSuspended(int i) 
    mGoogleApiClient.connect();


@Override
public void onConnectionFailed( ConnectionResult connectionResult) 



@Override
protected void onStart() 
    super.onStart();
    mGoogleApiClient.connect();


@Override
protected void onStop() 
    super.onStop();
    if (mGoogleApiClient.isConnected()) 
        mGoogleApiClient.disconnect();
    


@Override
public void onMapClick(LatLng latLng) 
    mMap.clear();
    marker = mMap.addMarker(new MarkerOptions()
            .position(latLng).title("¿Aquí?"));
    mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
    latitud = latLng.latitude;
    longitud = latLng.longitude;

无论如何，当我进行调试时，我在方法 onMapClick 中放置断点并没有停在那里，我已经使用它并且工作了，但是直到今天我才实现融合位置，我遇到了这个问题。

如果有人能帮我解决这个问题，我将不胜感激。

谢谢。

您忘记为地图设置GoogleMap.OnMapClickListener。

将此添加到您的onMapReady：
