Get latitude and longitude from Google Maps onclick in Android

To get the latitude and longitude from Google Maps onclick in Android, you can use the Google Maps API and handle the OnMapClickListener. Here is an example of how to achieve this:

First, you need to include the Google Maps API in your Android project. You can do this by adding the following dependency in your app-level build.gradle file:

        <dependencies>
            ...
            <implementation 'com.google.android.gms:play-services-maps:17.0.0' />
        </dependencies>

Next, in your Android activity or fragment, add a MapView to display the Google Map:

        <com.google.android.gms.maps.MapView
            android:id="@+id/mapView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

In the corresponding Java or Kotlin file, initialize the MapView and handle the OnMapClickListener:

        // In onCreate or onCreateView method
        mMapView = findViewById(R.id.mapView);
        mMapView.onCreate(savedInstanceState);
        mMapView.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                // Set the OnMapClickListener
                googleMap.setOnMapClickListener(new OnMapClickListener() {
                    @Override
                    public void onMapClick(LatLng latLng) {
                        double latitude = latLng.latitude;
                        double longitude = latLng.longitude;
                        // Do something with the latitude and longitude values
                    }
                });
            }
        });
        
        // Important: Don't forget to handle the lifecycle events of the MapView
        @Override
        public void onResume() {
            super.onResume();
            mMapView.onResume();
        }
        
        @Override
        public void onPause() {
            super.onPause();
            mMapView.onPause();
        }
        
        @Override
        public void onDestroy() {
            super.onDestroy();
            mMapView.onDestroy();
        }
        
        @Override
        public void onLowMemory() {
            super.onLowMemory();
            mMapView.onLowMemory();
        }

The above code sets an OnMapClickListener on the GoogleMap instance and retrieves the latitude and longitude coordinates when the map is clicked. You can then use these values to perform further actions, such as displaying a marker or updating your application’s UI.
