我正在使用 osmdroid 映射 API 的 android 映射应用程序中工作，直到现在我能够显示地图（使用 MapView 类），但我想知道如何在地图上显示我的位置，在我阅读后我知道有一个名为 MyLocationOverlay 的类我正在尝试使用它，但应用程序返回一个空白页。这是我的代码：

public class AbodyActivity extends Activity 
{
private MapView mapView; 
private MapController mapController;
private MyLocationOverlay myLocationoverlay;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    initializemap();
    myLocationoverlay = new MyLocationOverlay(this, mapView);
    myLocationoverlay.disableMyLocation(); // not on by default
    myLocationoverlay.disableCompass();
    myLocationoverlay.disableFollowLocation();
    myLocationoverlay.setDrawAccuracyEnabled(true);
    myLocationoverlay.runOnFirstFix(new Runnable() {
    public void run() {
            mapController.animateTo(myLocationoverlay
                    .getMyLocation());
        }
    });
    mapView.getOverlays().add(myLocationoverlay);
}
public void initializemap()
{
mapView = (MapView) this.findViewById(R.id.mapView); 
mapView.setTileSource(TileSourceFactory.MAPNIK); 
mapView.setBuiltInZoomControls(true); 
mapView.setMultiTouchControls(true); 
mapController = this.mapView.getController();     
mapController.setZoom(6);
}

}

这也是我使用的权限：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Are you sure that:

myLocationoverlay.disableMyLocation();

Doesn't disable the location finder methods so your Runnable is never called?
