Show text on polygon android Google map v2 -

i using polygons on map , want have text on them. there possible way this? tried put simple text on map point didn't make it.

 private void addpolygon(region reg) {              polylineoptions polylineoptions = new polylineoptions();              arraylist<latlng> coordlist=reg.getallpoints();              coordlist.add(coordlist.get(0));              int regcolor = reg.getcolor();              string regname = reg.getname();              //want put name on region              polylineoptions.addall(coordlist);              polylineoptions               .width(5)               .color(color.black);              if (regcolor != 0)                  polylineoptions                   .color(regcolor);              map.addpolyline(polylineoptions);             //text on shape?         } 

you can create marker custom icon, , draw text on icon. can use method this:

public marker addtext(final context context, final googlemap map,         final latlng location, final string text, final int padding,         final int fontsize) {     marker marker = null;      if (context == null || map == null || location == null || text == null             || fontsize <= 0) {         return marker;     }      final textview textview = new textview(context);     textview.settext(text);     textview.settextsize(fontsize);      final paint painttext = textview.getpaint();      final rect boundstext = new rect();     painttext.gettextbounds(text, 0, textview.length(), boundstext);     painttext.settextalign(align.center);      final bitmap.config conf = bitmap.config.argb_8888;     final bitmap bmptext = bitmap.createbitmap(boundstext.width() + 2             * padding, boundstext.height() + 2 * padding, conf);      final canvas canvastext = new canvas(bmptext);     painttext.setcolor(color.black);      canvastext.drawtext(text, canvastext.getwidth() / 2,             canvastext.getheight() - padding - boundstext.bottom, painttext);      final markeroptions markeroptions = new markeroptions()             .position(location)             .icon(bitmapdescriptorfactory.frombitmap(bmptext))             .anchor(0.5f, 1);      marker = map.addmarker(markeroptions);      return marker; } 

you need set location latlng of marker , have calculate region (for example first point of geometry, last point, random point, centroid, ...).

also, take account drawing lot of markers have negative effect in performance.
