我试图在地图覆盖上放置一个标记,然后在用户选择drawable时显示一个对话框.问题是事件似乎重叠.单击地图并绘制标记后,onTap会立即触发,因为我刚刚绘制了标记,它直接位于onTap事件下,因此我的对话框始终会触发.有没有人对如何使这些事件互相排斥？

以下是地图活动的代码:

public class SelectGameLocation extends MapActivity implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener  {

    private MapView mapView = null;
    private SelectGameLocationItemizedOverlay selectLocationOverlay = null;
    private List<Overlay> mapOverlays = null;
    private GestureDetector gestureDetector = null;

    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);

        //set the layout
        setContentView(R.layout.activity_select_game_location);

        //configure activity for double clicks
        gestureDetector = new GestureDetector(this);
        gestureDetector.setOnDoubleTapListener(this);

        //create and configure mapview
        mapView = (MapView) findViewById(R.id.selectGameLocation);
        mapView.setBuiltInZoomControls(true);
        mapView.setHapticFeedbackEnabled(true);

        //configure the overlay to draw the icons on the map
        mapOverlays = mapView.getOverlays();
        Drawable drawable = this.getResources().getDrawable(R.drawable.map_icon);
        selectLocationOverlay …
