阅读更多关于 How do I show a marker in Maps launched by geo URI Intent?

问题 I have a application where I want to show different locations (one at the time, picked by user input) by launching Google Maps with their specific geo coordinates. I\'m currently using this (with real lat. and long. values of course): Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(\"geo:<lat>,<long>?z=17\")); startActivity(intent); It\'s quite exactly what I want, except that it doesn\'t show any indicator or marker for the specified point.

阅读更多关于 MapView in a Fragment (Honeycomb)

问题 now that the final SDK is out with google apis - what is the best way to create a Fragment with a MapView? MapView needs a MapActivity to work right. Having the Activity managing the Fragments inherit from MapActivity (bad solution because it goes against the idea that Fragments are self contained) and use a regular xml based layout does not work.
