如何在openstreetmap中進行觸摸事件android

我在OSM地圖中受苦。這對我來說是新的。我想打印Toast消息，單擊並長按我嘗試所有可以做的事情。但我沒有找到正確的方法。這是我的代碼。請給我正確的方式來解決這個問題。謝謝你。請如何在openstreetmap中進行觸摸事件android

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.map1); 
    final MapView mapView = (MapView) findViewById(R.id.mapViewosm); 
    mapView.setBuiltInZoomControls(true); 

    MapController myMapController = mapView.getController(); 
    myMapController.setZoom(13); 

    ScaleBarOverlay myScaleBarOverlay = new ScaleBarOverlay(this); 
    mapView.getOverlays().add(myScaleBarOverlay); 

    Drawable marker = getResources().getDrawable(
      android.R.drawable.star_big_on); 
    int markerWidth = marker.getIntrinsicWidth(); 
    int markerHeight = marker.getIntrinsicHeight(); 
    marker.setBounds(0, markerHeight, markerWidth, 0); 

    ResourceProxy resourceProxy = new DefaultResourceProxyImpl(
      getApplicationContext()); 

    myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy); 
    mapView.getOverlays().add(myItemizedOverlay); 

    GeoPoint myPoint1 = new GeoPoint(0 * 1000000, 0 * 1000000); 
    myItemizedOverlay.addItem(myPoint1, "myPoint1", "myPoint1"); 
    GeoPoint myPoint2 = new GeoPoint(50 * 1000000, 50 * 1000000); 
    myItemizedOverlay.addItem(myPoint2, "myPoint2", "myPoint2"); 

    myLocationOverlay = new MyLocationOverlay(this, mapView); 
    mapView.getOverlays().add(myLocationOverlay); 
    myLocationOverlay.enableMyLocation(); 

    myLocationOverlay.runOnFirstFix(new Runnable() { 
     public void run() { 
      mapView.getController().animateTo(
        myLocationOverlay.getMyLocation()); 
     } 
    }); 
    // 2nd 
    // // --- Create Overlay 
    // overlayItemArray = new ArrayList<OverlayItem>(); 
    // 
    // DefaultResourceProxyImpl defaultResourceProxyImpl = new 
    // DefaultResourceProxyImpl(

    // MyItemizedIconOverlay myItemizedIconOverlay = new

    // .getLastKnownLocation(LocationManager.GPS_PROVIDER); 
    // if (lastLocation != null) { 
    // updateLoc(lastLocation); 
    // } 

    // 1st 
    anotherOverlayItemArray = new ArrayList<OverlayItem>(); 
    anotherOverlayItemArray.add(new OverlayItem("0, 0", "0, 0", 
    new GeoPoint(0, 0))); 
    anotherOverlayItemArray.add(new OverlayItem("US", "US", new GeoPoint(
    38.883333, -77.016667))); 
    ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay = new 
    ItemizedIconOverlay<OverlayItem>(
    this, anotherOverlayItemArray, myOnItemGestureListener); 
    mapView.getOverlays().add(anotherItemizedIconOverlay); 

} 

// 1st 
OnItemGestureListener<OverlayItem> myOnItemGestureListener = new 
OnItemGestureListener<OverlayItem>() { 

@Override 
public boolean onItemLongPress(int arg0, OverlayItem arg1) { 
// TODO Auto-generated method stub 

Toast.makeText(getApplicationContext(), "long tap", 
Toast.LENGTH_SHORT).show(); 
return true; 
} 

@Override 
public boolean onItemSingleTapUp(int index, OverlayItem item) { 

Toast.makeText(getApplicationContext(), "single tap", 
Toast.LENGTH_SHORT).show(); 
Toast.makeText(
Map.this, 
item.mDescription + "\n" + item.mTitle + "\n" 
+ item.mGeoPoint.getLatitudeE6() + " : " 
+ item.mGeoPoint.getLongitudeE6(), 
Toast.LENGTH_LONG).show(); 
return true; 
} 

};

最後我得到了這個問題的解決方案。這裏是我的回答

@Override 
    public boolean onSingleTapConfirmed(MotionEvent e, MapView mapView) { 

     Projection proj = mapView.getProjection(); 
     p = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY()); 
     proj = mapView.getProjection(); 
     loc = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY()); 
     String longitude = Double 
     .toString(((double) loc.getLongitudeE6())/1000000); 
     String latitude = Double 
     .toString(((double) loc.getLatitudeE6())/1000000); 
     Toast toast = Toast.makeText(getApplicationContext(), 
     "Longitude: " 
     + longitude + " Latitude: " + latitude, Toast.LENGTH_SHORT); 
     toast.show(); 
     return true; 
    } 

private void addLocation(double lat, double lng) { 
    // ---Add a location marker--- 

    p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6)); 

    Drawable marker = getResources().getDrawable(
      android.R.drawable.star_big_on); 

    int markerWidth = marker.getIntrinsicWidth(); 
    int markerHeight = marker.getIntrinsicHeight(); 

    marker.setBounds(0, markerHeight, markerWidth, 0); 

    ResourceProxy resourceProxy = new DefaultResourceProxyImpl(
      getApplicationContext()); 

    myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy); 

    List<Overlay> listOfOverlays = mapView.getOverlays(); 
    listOfOverlays.clear(); 
    listOfOverlays.add(myItemizedOverlay); 

    mapView.invalidate(); 
}

在OSM可以使用MapEventsReceiver像吹檢測水龍頭：

MapEventsReceiver mReceive = new MapEventsReceiver() { 
     @Override 
     public boolean singleTapConfirmedHelper(GeoPoint p) { 

      // write your code here 

      return false; 
     } 

     @Override 
     public boolean longPressHelper(GeoPoint p) { 
      // write your code here 
      return false; 
     } 
    }; 
    MapEventsOverlay OverlayEvents = new MapEventsOverlay(getBaseContext(), mReceive); 
    map.getOverlays().add(OverlayEvents);
