Determine what kind of VIEW in several views has a gesture (double-click, swipe left, swipe right, etc.)?

Question

I have a scrollview with several horizontal relativelayout views ... one for each record in the database ... which are created programmatically.

I need to determine what kind of gestures affect the look ... click, double click and scroll left / right.

Of course, CLICK, which I could contact:

RelativeLayout rlView = new RelativeLayout(this); rlView.setId(10000+myrecordid); rlView.setOnClickListener(myviewclick); 

and myviewclick:

 private View.OnClickListener myviewclick = new View.OnClickListener() { public void onClick(View v) { Integer i=v.getId()-10000; // Do some processing on this view } }; 

From what I found on the Internet, I tried to make a gesture like this:

 rlView.setOnTouchListener(myviewtouch); 

using this code:

 private View.OnTouchListener myviewtouch = new View.OnTouchListener(){ public boolean onTouch(View v, MotionEvent event) { return gestureDetector.onTouchEvent(event); } GestureDetector gestureDetector = new GestureDetector(new GestureDetector.SimpleOnGestureListener() { @Override public boolean onDoubleTap(MotionEvent e) { Log.i("MYLOG","double tap"); return true; } @Override public boolean onSingleTapConfirmed(MotionEvent e) { Log.i("MYLOG","SingleTapConfirmed"); return true; } @Override public void onLongPress(MotionEvent e) { Log.i("MYLOG","LongPress"); } public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { if (e1.getX()<e2.getX()) Log.i("MYLOG","Fling Right"); else Log.i("MYLOG","Fling Left"); return true; } }); }; 

According to MYLOG, I get appropriate gestures as needed. The problem is that I do not know how to get the identifier of the view in which this gesture was. I know that it is in onTouch , but called gestureDetector.OnTouchEvent to determine the movement ... and I got lost at that point.

I searched all StackOverflow and other sites for several hours ... they all show deviations in how to define a gesture ... but without having problems finding any problems using several kinds that I can use.

Any help would be greatly appreciated.

I think I get it. This is probably not the most elegant way to do this, and there may be other “problems” due to its handling in this way, but at the moment it works. But if others find this problem, here is how I worked on it:

This is how my modified code worked. I added a public variable called vTouch :

 private View.OnTouchListener myviewtouch = new View.OnTouchListener(){ public View vTouch; public boolean onTouch(View v, MotionEvent event) { vTouch=v; return gestureDetector.onTouchEvent(event); } GestureDetector gestureDetector = new GestureDetector(new GestureDetector.SimpleOnGestureListener() { @Override public boolean onDoubleTap(MotionEvent e) { Integer viewId=vTouch.getId(); Log.i("MYLOG","double tap in view: "+viewId); return true; } @Override public boolean onSingleTapConfirmed(MotionEvent e) { Integer viewId=vTouch.getId(); Log.i("MYLOG","SingleTapConfirmed in view: "+viewId); return true; } @Override public void onLongPress(MotionEvent e) { Integer viewId=vTouch.getId(); Log.i("MYLOG","LongPress in view: "+viewId); } public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { Integer viewId=vTouch.getId(); if (e1.getX()<e2.getX()) Log.i("MYLOG","Fling Right in view: "+viewId); else Log.i("MYLOG","Fling Left in view: "+viewId); return true; } }); }; 

Using the vTouch internal public variable, I can now refer to the view in every gesture event where the “view” is ever required for this gesture to appear.
