Android guide bee map development example: Map Translation

RasterMap can be used to translate a map. panTo moves the map to the coordinates of the specified longitude and latitude. panDirection (dx, dy) translates the map into dx and dy pixels from the current position.
GuidebeeMapView implements TouchEvent processing. You can use the Touch event to pan the map. The following example uses the menu to pan the map above, down, left, and right.
