On Jul 14, 7:35 pm, Mark Murphy Just pass in the activity to your ItemizedOverlay's subclass' constructor, and use it to create your Toast. be careful though, since passing Activity context to Toast can in some situations be dangerous, see: http://groups.google.com/group/android-developers/browse_thread/thread/de2f0cebec002303/aae1c4a709e63548#aae1c4a709e63548 thanks pskink --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Thanks. Good point. I have seen the behavior described in the thread you pointed to.

Hi Mark, Thanks. What I meant is that I thought that in your example, SitesOverlay is an inner class of the map activity NooYawk. In my case, the custom itemized overlay class is not an inner class of the map activity. This means that an entry like NooYawk.this will not work. Am I wrong? I have not been able to get it to work.

[android-developers] Re: onTap display toast or message
Scott Mikolyski (sc...@mikolyski.com) solved my problem. He suggested I add a private context to the custom itemized overlay, modify the itemized overlay constructor to assign a context to the private contxt. Then pass the context of the map activity to the instantiation of the custom itemized overlay. Alex P.S. I am still interested in implementing a display of detail marker information when hovering over a marker as implemented in many location/map based products.
