Question

当我点击Android中的地图中的某个地方时，它显示警报对话框？要保存的位置到特定列表，例如我的地方或最喜欢的，这样我可以移动的地方，尤其是在列表中提前

感谢......

Answer 1

你试过覆盖你的customOverlays中的onTap方法？

public class CustomOverlays extends ItemizedOverlay<OverlayItem> 
{ 
    @Override 
    public boolean onTap(GeoPoint arg0, MapView arg1) { 
     // TODO Auto-generated method stub 
     return super.onTap(arg0, arg1); 
    } 
}

public class MapViewer extends MapActivity { 

MapView mapView; 

MapController mapController; 

GeoPoint mgeoPoint; 

Drawable marker; 

MyLocationOverlay mLocationOverlay; 

MotionEvent e; 


@Override 
protected void onCreate(Bundle icicle) { 

    // TODO Auto-generated method stub 
    super.onCreate(icicle); 
    setContentView(R.layout.main); 

    mapView = (MapView) findViewById(R.id.mapView); 

    mapController = mapView.getController(); 

    mapView.setBuiltInZoomControls(true); 

    mapView.setStreetView(true); 


    marker = getResources().getDrawable(R.drawable.pushpin); 

    marker.setBounds(0, 0, marker.getIntrinsicWidth(), marker 
      .getIntrinsicHeight()); 

    mapView.getOverlays().add(new MapOverlay(marker)); 


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

    setViewLocation(); 
} 


@Override 
protected Dialog onCreateDialog(int id) { 

    // TODO Auto-generated method stub 

    switch (id) { 
     case 0: 
      return new AlertDialog.Builder(this).setTitle("Hello").setIcon(
        R.drawable.ic_launcher).setPositiveButton("Yes", 
        new OnClickListener() {

        Toast.makeText(getApplicationContext(), "Dismiss", 
          Toast.LENGTH_SHORT).show(); 
       } 

      }).create(); 


     default:

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

    mapController.animateTo(mgeoPoint); 
    mapController.setZoom(15); 

    mapView.invalidate(); 

}

    List<OverlayItem> ListofGeopoints = new ArrayList<OverlayItem>(); 


    public MapOverlay(Drawable defaultMarker) { 

     super(defaultMarker); 

     ListofGeopoints.add(new OverlayItem(getPoint(22.716221, 75.896816),

     populate(); 

    } 


    @Override

     return true;

    String add = ""; 

    List<Address> add_List = new ArrayList<Address>(); 


    private void getAddress() { 

     add_List = ReverseGeocode 
       .getFromLocation(35.594227, -105.223618, 2); 

    } 


    @Override
