In the below example blog I have Implemented a Google map to get lat and long from address, In Google map I have added search address functionality. When user input address(place) name in an EditText and on clicking button, the application draws corresponding location marker. By using GeoCoder we get address from address arrayList.

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

        private GoogleMap mMap;

        LatLng latLng;
        private  GoogleMap.OnInfoWindowClickListener infoWindowClickListener;
        private HashMap<String,String>markers;


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

            mMap = mapFragment.getMap();

        mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
      @Override
      public void onMapClick(LatLng arg0) {
          latLng =arg0;

          // Clears the previously touched position
          mMap.clear();


          // Creating a marker
          MarkerOptions markerOptions = new MarkerOptions();

          // Setting the position for the marker
          markerOptions.position(latLng);


          // Animating to the touched position
          mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));


          Marker marker = mMap.addMarker(markerOptions);


      }
  });
        }

        public void onMapSearch(View view) {
            EditText locationSearch = (EditText) findViewById(R.id.editText);
            String location = locationSearch.getText().toString();
            List<Address> addressList = null;

            if (location != null || !location.equals("")) {
                Geocoder geocoder = new Geocoder(this);
                try {
                    addressList = geocoder.getFromLocationName(location, 1);

                } catch (IOException e) {
                    e.printStackTrace();
                }
                Address address = addressList.get(0);
                LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());

                mMap.addMarker(new MarkerOptions().position(latLng).title("You Clicked"));
                mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
            }
        }

        @Override
        public void onMapReady(GoogleMap googleMap) {
            mMap = googleMap;

            mMap.setMyLocationEnabled(true);
        }
    }
