android - how to open up a map of a particular city using google APIs in android

Question

I have been able to open up a map of the world through code and mark a few places. However, I always have to zoom down to the city, which takes a little while. Is there any way to directly open up a map of a particular city?

Answer 1

例如，您可以将moveCamera与您最后存储的位置（lat、lng 和 zoomLevel）一起使用。

final LatLng location = new LatLng(..., ...);// Loaded from SharedPreferences maybe.

// Move the camera to location with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 15));

Answer 2

您可以使用此示例代码将地图直接设置为您的城市坐标（lat、lng）并自动缩小到指定级别：

// Set desired lat lng location, and zoom level (for example 10)
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(locationCity.getLatitude(), locationCity.getLongitude()), 10);
// Move the camera to location
gMap.animateCamera(cameraUpdate);
