içinde sırasıyla [GestureDetector.OnGestureListener] [1] sınıf yöntemi [onSingleTapUp (MotionEvent)] [2]: a kademe kadar MotionEvent que Oluştuğunda fark Android
Onaylanmış tetiklenen o.
Bu yöntem aynı onclick'in işlevine sahiptir? Onclick yönteminden istediğim aynı davranışı uygulamak için bu yöntemi kullanabilir miyim?
Bazı testler yaptım ve cevabın YES olduğu görülüyor, onclick yerine onSingleTapUp kullanabilirsiniz. OnSingleTapUp yöntemi, çift veya uzun tıklatmanın basit bir tıklamasını iyi bir şekilde ayırt edebilir. Benim testi: Basit bir tıklama için
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;
