SupportMapFragment 设置 google 地图缩放级别

Question

如何设置 SupportMapFragment 的缩放级别？我尝试了一些我在类似问题中找到的答案，比如这个回答买了一个名叫 Rob 的人，他提议：

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));

但是这个解决方案没有用。那么，知道我使用 SupportMapFragment.

如何设置缩放级别

Answer 1

如果您的当前位置不为空，请尝试此代码，它会起作用

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)

Answer 2

Marker currentMarker;

    MarkerOptions marker = new MarkerOptions().position(new
                     LatLng(Double.
                     parseDouble(lat),Double.parseDouble(lon))).title(title);
                     marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_schoolbus));
                     currentMarker =  map.addMarker(marker);
                     currentMarker.showInfoWindow();
                     currentMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_schoolbus));
                     map.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(Double.parseDouble(lat),Double.parseDouble(lon)), 15));
