Android SupportMapFragment设置谷歌地图缩放级别

如何设置

SupportMapFragment

的缩放级别？ 我尝试了一些在类似问题中找到的答案，比如下面这个回答：买一个叫Rob的家伙，他提出：

LatLng currentLocation = mService.getCurrentLocation();
    CameraPosition cameraPosition = new CameraPosition.Builder()
            .target(currentLocation)    // Sets the center of the map to the current location of the user
            .zoom(17)                   // Sets the zoom
            .bearing(90)                // Sets the orientation of the camera to east
            .tilt(30)                   // Sets the tilt of the camera to 30 degrees
            .build();                   // Creates a CameraPosition from the builder
    mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

但这个解决方案不起作用。那么，在知道我使用了

SupportMapFragment

的情况下，如何设置缩放级别？如果您的当前位置不为空，请尝试此代码，它将正常工作

LatLng currentLocation = mService.getCurrentLocation();
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(currentLocation , 16);
mMap.addMarker(new MarkerOptions().position(location).title(""));
mMap.moveCamera(CameraUpdateFactory.newLatLng(currentLocation ));
mMap.animateCamera(cameraUpdate)
