Android Maps control

If I use the Intent to fire up default maps app on emulator/device, how can I gain control on the clicks/touch on the map. e.g. I want to find all Pizza places in my location. It is damn easy if I use geo URI. String uri = "geo:"+ 39.967571 + "," + -75.532123 + "?q=pizza"; startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri))); Once the map is started I loose control, I want to be able to extract some values based on where the user has clicked.

If I extend MapActivity I am not getting what I desire i.e. list of business based on a parameter. Intent myIntent = new Intent(YYYYY.this, XXXX.class); YYYYY.this.startActivity(myIntent); This will fire up XXXX activity which exten开发者_开发问答ds MapActivity. How do I get the list of Pizza places based on current location. I tried using geocoder with parameters but results weren't reliable at all.

You don't. That's not your app.

You're going to have to write the "list of business based on a parameter" logic yourself, with some third-party source of "list of business" data.
