android - Google Maps v2 设置缩放级别

Question

当我在 Android 中启动 Google map 时，它会显示整个世界。我需要更改什么才能将缩放设置为标记？这是代码。谢谢

        googlemap.getUiSettings().setZoomControlsEnabled(true);
    googlemap.getUiSettings().setMyLocationButtonEnabled(true);


    LatLng cameraLatLng = sfLatLng;
    float cameraZoom = 17;


    if(savedInstanceState != null){
        mapType = savedInstanceState.getInt("map_type", GoogleMap.MAP_TYPE_NORMAL);

        double savedLat = savedInstanceState.getDouble("lat");
        double savedLng = savedInstanceState.getDouble("lng");
        cameraLatLng = new LatLng(savedLat, savedLng);

        cameraZoom = savedInstanceState.getFloat("zoom", 30);

        googlemap.setMapType(mapType);
        googlemap.animateCamera(CameraUpdateFactory.newLatLngZoom(cameraLatLng, cameraZoom));

试试这个---->

  map.addMarker(new MarkerOptions().position(latlng)).setVisible(true);

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

  // Zoom in, animating the camera.
  map.animateCamera(CameraUpdateFactory.zoomTo(14), 2000, null);
