i have made lot of markers now i want each information window of marker must be unique i have written xml for information window but its not working aaccordingly everytime a single image shows up.

                            // Setting a custom info window adapter for the google map
                                    myMap.setInfoWindowAdapter(new InfoWindowAdapter() {

                                        // Use default InfoWindow frame

                                        public View getInfoWindow(Marker arg0) {
                                            return null;
                                        }

                                        // Defines the contents of the InfoWindow

                                        public View getInfoContents(Marker marker) {

                                            // Getting view from the layout file info_window_layout
                                            View v = getLayoutInflater().inflate(
                                                    R.layout.info_window_layout, null);

                                            // Getting the position from the marker
                                            LatLng latLng = marker.getPosition();
                                            Double latitude=latLng.latitude;
                                            Double langitude=latLng.longitude;

                                            String lat = String.format("%.6f", latitude);
                                            String lng = String.format("%.6f", langitude);

                                            Toast.makeText(getApplicationContext(), lat+"----"+lng,Toast.LENGTH_SHORT).show();
                                            // Getting reference to the TextView to set longitude
                                        TextView tvLng = (TextView) v.findViewById(R.id.tv1);
                                        ImageView icon = (ImageView) v.findViewById(R.id.icons);

                                        if(lat.equals("73.057130") && lng.equals("33.721140"))
                                        {
                                            icon.setImageResource(R.drawable.hbl_icon);

                                        }
                                        else
                                        {

                                            icon.setImageResource(R.drawable.alflah_icon);
                                        }
                                            // Returning the view containing InfoWindow contents
                                            return v;

                                        }

                                    });

in myMap.setInfoWindowAdapter the toast is showing the same latitude but the information window appearing is not showing the image in if condition and always showing a image in else condition.everything works fine but the image is not showing proper kindly help. my xml is :

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
