title: android: add a textview about map marker for ALL markers
body: <p>Our designer has provided me with a custom icon to display on maps. Our MapView will display several icons of those at the same time.</p>
  
  <p>The tricky part: every icon should have a text above it displaying what it is - and all icons should show this text always simultaneously. </p>
  
  <p>So I know that there is .showInfoWindow(), but that only shows one window at a time and only onclick.</p>
  
  <p>I found this SO post:
  <a href="https://stackoverflow.com/questions/17837510/map-markers-with-text-in-google-maps-android-api-v2?rq=1">Map Markers with text in Google Maps Android API v2</a></p>
  
  <p>but that's using google's library and it only is able to use a colored rectangle as a text holder, not, as in my case, an icon AND the text above.</p>
  
  <p>Searching, I found several ideas but none seems to work. My last attempt:</p>
  
  <pre><code> LatLng pos = new LatLng(lat, lng);
  
                  Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.icon).copy(Bitmap.Config.ARGB_8888, true);
                  Canvas canvas = new Canvas(bm);
                  Paint paint = new Paint();
                  paint.setStyle(Paint.Style.FILL);
                  paint.setColor(Color.WHITE);
                  paint.setTextAlign(Paint.Align.CENTER);
                  paint.setTextSize(11));
                  canvas.drawText(item.getString("name"), 10, -20, paint);
  
                  Marker marker = mMap.addMarker(new MarkerOptions()
                                  .position(pos)
                                  .title(item.getString("name"))
                                  .icon(
                                      BitmapDescriptorFactory.fromBitmap(bm)
                                          )
  
                  );
  </code></pre>
  
  <p>But I still can only see the icon and no text.</p>
