Differenz zwischen Klick und tippt in Android

Question

Die [GestureDetector.OnGestureListener] [1] Klasse hat die Methode [onSingleTapUp (Motion)] [2]:

benachrichtigen, wenn ein Wasserhahn mit dem Motion que up Tritt ausgelöst es.

Diese Methode hat die gleiche Onclick-Funktion? Kann ich diese Methode verwenden, um dasselbe Verhalten wie von der onclick-Methode zu implementieren?

Answer 1

Ich habe einige Tests und es scheint, dass die Antwort YES ist, können Sie onSingleTapUp anstelle onclick verwenden. Die Methode onSingleTapUp kann mit einem einfachen Klick auf einen doppelten oder langen Klick gut unterscheiden. Mein 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()); 
     } 
    } 
} 

Ergebnis für einfachen Klick:
