我从这里获取 Google maps api v1 项目：http ://www.androidhive.info/2012/01/android-working-with-google-maps/

然后我想将其转换为 Google maps api v2。

之后，它显示“不幸的是 GoogleMaps 已停止”。

3天我努力解决这个问题，但没有解决。请帮我

不需要使用public class AddItemizedOverlay extends ItemizedOverlay<OverlayItem>

要添加标记，请参见粗体文本。

public class MapActivity extends Activity implements OnMarkerDragListener
{

    private GoogleMap map;
    Geocoder geocoder;
    Double lat,lon;
    static LatLng questionLoc=new LatLng(53.558, 9.927);
    Marker questionMarker;
    SharedPreferences mapPref;
    List<Address> addresses;
    MarkerOptions mark;
    String address,city,country,admin,subAdmin,location;
    @SuppressLint("NewApi")
    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ask_map);
        Intent mapIntent=getIntent();
        lat=Double.parseDouble(mapIntent.getStringExtra("curr_lat"));
        lon=Double.parseDouble(mapIntent.getStringExtra("curr_long"));
        if(map==null)
            map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        map.setMyLocationEnabled(true);
        map.setOnMarkerDragListener(this);
        questionLoc=new LatLng(lat,lon);

mark= new MarkerOptions().position(questionLoc).title("Location").snippet(getIntent() .getStringExtra("Location")).draggable(true) .icon(BitmapDescriptorFactory.fromResource(R.drawable.mappin) );

    questionMarker = map.addMarker(mark);
    geocoder = new Geocoder(this, Locale.getDefault());
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(questionLoc, 15));
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2500, null);

从 v1 移植到 v2 没有简单的方法。

最好的办法是删除所有与地图相关的代码，并遵循地图 v2 的官方文档或找到自己的 v2 教程。
