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));

但是这个解决方案并没有奏效。因此，如何知道我使用SupportMapFragment。

Answer 1

如果您当前的位置不为null，请尝试使用此代码

$options = array(
'hostname' => 'xxx.xxx.xxx.xxx',
'login'    => '',
'password' => '',
'port'     => 8983,
'path'     => 'solr/<collection name>'
);

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));
