问题 I am trying to put a Google map inside a scroll view, so that the user can scroll down other contents to see the map.

由 主宰稳场 提交于 2019-11-26 08:05:22
问题 I\'m trying to mess around with the Maps API V2 to get more familiar with it, and I\'m trying to start the map centered at the user\'s current location. Using the map.setMyLocationEnabled(true); statement, I am able to show my current location on the map. This also adds the button to the UI that centers the map on my current location.
