    In the below example code I have described to add a  marker with Infowindow. Here I have used array list for adding marker items, then I have created plotMarkers method, in this method, it will addMarker by passing MarkerOptions as a parameter. I have used LatLng to define the position to add the marker. In next step, I have used setInfoWindowAdapter method and in getInfoContents I have inflated window Layout for CustomWindow layout.

     

    public class MapsActivity extends Activity {
        private GoogleMap mMap;
        private ArrayList<MyMarker> mMyMarkersArray = new ArrayList<MyMarker>();
        private HashMap<Marker, MyMarker> mMarkersHashMap;
        ImageView image;
        MyMarker myMarker;
        
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_maps);
            
            // Initialize the HashMap for Markers and MyMarker object
            mMarkersHashMap = new HashMap<Marker, MyMarker>();
            mMyMarkersArray.add(new MyMarker("Kanpur", "icon1", Double.parseDouble("26.44721"), Double.parseDouble("80.32242")));
            mMyMarkersArray.add(new MyMarker("United States", "icon2", Double.parseDouble("33.7266622"), Double.parseDouble("-87.1469829")));
            mMyMarkersArray.add(new MyMarker("Canada", "icon3", Double.parseDouble("51.8917773"), Double.parseDouble("-86.0922954")));
            mMyMarkersArray.add(new MyMarker("England", "icon4", Double.parseDouble("52.4435047"), Double.parseDouble("-3.4199249")));
            mMyMarkersArray.add(new MyMarker("Espaa", "icon5", Double.parseDouble("41.8728262"), Double.parseDouble("-0.2375882")));
            mMyMarkersArray.add(new MyMarker("Portugal", "icon6", Double.parseDouble("40.8316649"), Double.parseDouble("-4.936009")));
            mMyMarkersArray.add(new MyMarker("Deutschland", "icon7", Double.parseDouble("51.1642292"), Double.parseDouble("10.4541194")));
            mMyMarkersArray.add(new MyMarker("Atlantic Ocean", "icondefault", Double.parseDouble("-13.1294607"), Double.parseDouble("-19.9602353")));
            setUpMap();
            plotMarkers(mMyMarkersArray);
        }
    
        private void plotMarkers(ArrayList<MyMarker> markers) {
            if (markers.size() > 0) {
                for (MyMarker myMarker : markers) {
                    // Create user marker with custom icon and other options
                    MarkerOptions markerOption = new MarkerOptions().position(new LatLng(myMarker.getmLatitude(), myMarker.getmLongitude()));
                    markerOption.icon(BitmapDescriptorFactory.fromResource(R.drawable.one));
                    Marker currentMarker = mMap.addMarker(markerOption);
                    mMarkersHashMap.put(currentMarker, myMarker);
                    mMap.setInfoWindowAdapter(new MarkerInfoWindowAdapter());
                }
            }
        }
    
                    // Added infoWindow icons

  • hii, To search marker based on mLabel value and automat show infowindow, See below code-

    public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
    
        private GoogleMap mMap;
        MarkerOptions markerOptions;
        LatLng latLng;
        private GoogleMap.OnInfoWindowClickListener infoWindowClickListener;
        private HashMapmarker;
    
    
        @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.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
