gesture - difference between click and tap in Android -


the [gesturedetector.ongesturelistener][1] class has method [onsingletapup(motionevent)][2]:

notified when tap occurs motionevent que triggered it.

this method has same onclick's function? can use method implement same behavior want onclick method?

i did tests , seems answer yes, may use onsingletapup instead of onclick. onsingletapup method can differentiate simple click of double or long click. test:

public class mainfragmentscrollercontroller {     private mainfragment mfragment;     private gesturedetectorcompat mgesturedetector;      public mainfragmentscrollercontroller(mainfragment fragment)     {         mfragment = fragment;         mgesturedetector = new gesturedetectorcompat(mfragment.getactivity(), new gesturelistener());     }      public void setgesturelistener()     {         mfragment.myview.setontouchlistener(new ontouchlistener()         {             @override             public boolean ontouch(view v, motionevent event)             {                 boolean gestureresult = mgesturedetector.ontouchevent(event);                 log.i("gesturelistener", "gestureresult = " + gestureresult);                 return gestureresult;             }         });     }      public class gesturelistener extends simpleongesturelistener     {         private final string tag = "gesturelistener";         @override         public boolean ondown(motionevent event)         {             log.d(tag,"ondown: " + event.tostring());              return true;         }          @override         public boolean onfling(motionevent event1, motionevent event2, float velocityx, float velocityy)         {             log.d(tag, "onfling: " + event1.tostring()+event2.tostring());             return true;         }          @override         public boolean onscroll(motionevent event1, motionevent event2, float distancex, float distancey)         {             log.d(tag, "onscroll: " + event1.tostring()+event2.tostring());             return true;         }          @override         public boolean onsingletapup(motionevent event)         {             log.d(tag, "onsingletapup: " + event.tostring());             return true;         }          @override         public void onlongpress(motionevent event)         {             log.d(tag, "onlongpress: " + event.tostring());         }     } }

result simple click:
