copied!<p>Add a cache to your <code>InfoWindowAdapter</code> code and modify its <code>getInfoContents()</code> method to check it:</p> <pre><code> googleMap.setInfoWindowAdapter(new InfoWindowAdapter() { LruCache<Marker, View> cache = new LruCache<Marker, View>(8); // added // no change to getInfoWindow() @SuppressWarnings("unchecked") @Override public View getInfoContents(Marker marker) { View v = cache.get(marker); if (v == null) { LayoutInflater inflater = (LayoutInflater) MapsDemo.this .getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = inflater.inflate(R.layout.custom_info, null); new LocateGeopoint(v, marker).execute(marker.getPosition()); cache.put(marker, v); } return v; } }); </code></pre> <p>Adjust the code in your <code>LocateGeopoint</code> class, adding a reference to the <code>Marker</code> and calling <code>showInfoWindow()</code> after updating your TextView.</p> <pre><code>public class LocateGeopoint extends AsyncTask<LatLng, String, List<Address>> { // : Marker marker; // added public LocateGeopoint(View v, Marker marker) { // : this.marker = marker; // added } @Override protected void onPostExecute(List<Address> addresses) { super.onPostExecute(addresses); if(addresses!=null){ // : tv.setText(city); marker.showInfoWindow(); // added } } // no change to doInBackground() } </code></pre> <p>NOTE: This answer is really just a quick and dirty implementation (I haven't really tested it, but I think it should work) based on the answer from MaciejGórski on this question, please read the referenced post in that answer for more details :)</p>
