Android 如果触摸一个记号笔3秒钟，该如何做

我有一个谷歌地图api v2的应用程序，上面有一些标记。对于每个标记，如果我点击它，它会显示一个气球，上面有一些关于它的详细信息，如标题等。 使用SystemClock，它只等待3秒钟，但它会执行操作

如果用户在该标记上按X秒，我想做些什么？我试着用一根线，但没有成功

if (onBalloonTap(currentFocusedIndex, currentFocusedItem)) {
            long thisTime = 0;
            thisTime = SystemClock.uptimeMillis();
            if (thisTime > 3000) {

                DirectionsTask getDirectionsTask = new DirectionsTask();
                getDirectionsTask.execute(getCurrentLocation(),
                        currentFocusedItem.getPoint());
            }

像这样的

    GeoPoint p = null, currentP = null;
    boolean isActivated = false;
    view.setOnTouchListener(new OnTouchListener() { 
        public boolean onTouch(View v, MotionEvent event) { 
            if(event.getAction()==MotionEvent.ACTION_DOWN) {
                isActivated = false;
                currentP = p ;
            }
            if(currentP == p && event.getEventTime()-event.getDownTime()>3000 && !) { 
                Toast.makeText(AudioPlayerActivity.this, "3 sec", Toast.LENGTH_LONG).show(); 
                isActivated = true; //avoid displaying a lot of toast } return true; } });
            }
            if(event.getAction()==MotionEvent.ACTION_UP) {
                currentP = null; p = null;
            }
        }
    });

     //extends Overlay type, works if the method is called when "action down"
     public boolean onTap(GeoPoint p, MapView    mapView)  {
          this.p = p;
          return true;
     }

是否可以在视图中添加OnTouchListener？like:`boolean isActivated=false；view.setOnTouchListener（新的OnTouchListener（）{public boolean onTouch（view v，MotionEvent事件）{if（event.getEventTime（）-event.getDownTime（）>3000&！已激活）{Toast.makeText（AudioPlayerActivity.this，“3秒”，Toast.LENGTH_LONG）.show（）；isActivated=true；//避免显示大量toast}返回true；}）`我试图在itemizedoverlay中这样做。
