android如何在地圖上製作可拖動的pin v2

Question

嗨，所有我想製作一個pin ..問題是我無法找到與我的問題相關的來源。我已經檢查了commonsware的主題，但沒有一個涉及可拖動的pin。其實他們其中之一，但它是與地圖v1不v2相關。那麼我怎麼能做一個銷發生在用戶當前位置，然後可以拖動到地圖上的任何地方，當他們點擊的引腳..

這裏是具有銷（標記），並且得到用戶位置的示例代碼..

public class MainActivity extends AbstractMapActivity implements 
OnNavigationListener, OnInfoWindowClickListener, 
OnMyLocationChangeListener { 
private static final String STATE_NAV="nav"; 
private static final int[] MAP_TYPE_NAMES= { R.string.normal, 
    R.string.hybrid, R.string.satellite, R.string.terrain }; 
private static final int[] MAP_TYPES= { GoogleMap.MAP_TYPE_NORMAL, 
    GoogleMap.MAP_TYPE_HYBRID, GoogleMap.MAP_TYPE_SATELLITE, 
    GoogleMap.MAP_TYPE_TERRAIN }; 
private GoogleMap map=null; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 

if (readyToGo()) { 
    setContentView(R.layout.activity_main); 

    SupportMapFragment mapFrag= 
     (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map); 

    initListNav(); 

    map=mapFrag.getMap(); 

    if (savedInstanceState == null) { 
    CameraUpdate center= 
     CameraUpdateFactory.newLatLng(new LatLng(40.76793169992044, 
               -73.98180484771729)); 
    CameraUpdate zoom=CameraUpdateFactory.zoomTo(15); 

    map.moveCamera(center); 
    map.animateCamera(zoom); 
    } 

    addMarker(map, 40.748963847316034, -73.96807193756104, 
      R.string.un, R.string.united_nations); 
    addMarker(map, 40.76866299974387, -73.98268461227417,

    map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater())); 
    map.setOnInfoWindowClickListener(this);

savedInstanceState.putInt(STATE_NAV, 
          getSupportActionBar().getSelectedNavigationIndex()); 
} 

@Override

     String.format("%f:%f", lastKnownLocation.getLatitude(),

    } 
}

所有你需要的文件就在這裏

所有你需要做的是設置該標記可拖動

marker.setDraggable(true);
