Java android studio中与osmdroid不兼容的类型错误

我正在项目中使用

osmdroid

映射

我刚刚创建了一个示例项目，但出现以下错误

必需：org.osmdroid.view.MapController

找到：org.osmdroid.api.IMapController

我只是从osmdroid文档中复制了整个示例，尽管它显示了错误

我的

OsmDroidTest

类如下所示

import android.os.Bundle;
import android.app.Activity;

import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

public class OsmDroidTest extends Activity {
    /** Called when the activity is first created. */
    private MapController mapController;
    private MapView mapView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mapView = (MapView) findViewById(R.id.mapview);
        mapView.setTileSource(TileSourceFactory.MAPNIK);
        mapView.setBuiltInZoomControls(true);
        mapController = mapView.getController();    //error is at this line
        mapController.setZoom(15);
        GeoPoint point2 = new GeoPoint(51496994, -134733);
        mapController.setCenter(point2);
    }
    protected boolean isRouteDisplayed() {

        return false;
    }
}

getController（）似乎返回MapController实现的IMapController。将专用MapController MapController更改为IMapController MapController应该可以正常工作。@dnivra我更改了它，现在可以正常工作了！你能说出

MapController

和

IMapController

之间的区别吗？我从一个简单的示例中获取了上面的代码，它是由

MapController
