当我在推出Android版谷歌地图，它显示了整个世界。我需要什么改变，以便设置缩放到标记？下面是codeS。谢谢

  googlemap.getUiSettings（）setZoomControlsEnabled（真）。    googlemap.getUiSettings（）setMyLocationButtonEnabled（真）。    经纬度cameraLatLng = sfLatLng;    浮cameraZoom = 17;    如果（savedInstanceState！= NULL）{        地图类型= savedInstanceState.getInt（map_type，GoogleMap.MAP_TYPE_NORMAL）;        双savedLat = savedInstanceState.getDouble（纬度）;        双savedLng = savedInstanceState.getDouble（LNG）;        cameraLatLng =新的经纬度（savedLat，savedLng）;        cameraZoom = savedInstanceState.getFloat（放大，30）;        googlemap.setMapType（地图类型）;        googlemap.animateCamera（CameraUpdateFactory.newLatLngZoom（cameraLatLng，cameraZoom））; 

解决方案

试试这个---->

  map.addMarker（。新的MarkerOptions（）位置（经纬度））调用setVisible（真）。  //瞬间移动相机的位置为15的缩放。  map.moveCamera（CameraUpdateFactory.newLatLngZoom（经纬度，15））;  //放大，动画摄像机。  map.animateCamera（CameraUpdateFactory.zoomTo（14），2000，NULL）; 

When I launch Google maps in Android, it shows the whole world. What do i need to change so as to set the zoom to the marker? Here are the codes. Thanks

        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));

try this---->

  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);
