Adding Overlays on Map.

Question

Respected All, I add pins/markers(Overlays) on map to particular location and for each overlay I add onTap event which display pop up information on head of overlay, for that use table layout in which i use some pop image on which i display that location name and image button. following are some problems that i am facing.

1. Background image is not compressing as content change as i use wrap_content property to table layout.

2. To make that pop up invisible with on touch on map i use onTouch event on map but once it call, onTap event is not calling on any overlay.

3. Is there any pins/markers available in Android that will give in built pop up message as like i-phone that will display pop up message with content.

                                                                  Thank You
