Stop OnLongClickListener from firing while dragging

Question

I have a custom View with bitmaps on it that the user can drag about.

I want to make it so when they long click one of them I can pop up a context menu with options

Answer 1

I think I have this solved through tweaking my threshold approach.

First, I changed my onTouchEvent to look like this:

 public boolean onTouchEvent(MotionEvent event) {
     mMultiTouchController.handleDrag(event);
     return super.onTouchEvent(event);
 }

They now both fire, so I then changed my OnLongClickListener to the following:

 this.setOnLongClickListener(new View.OnLongClickListener() {
     @Override
     public boolean onLongClick(View v) {
         if (!mMultiTouchController.has_moved) {
             // Pop menu and done...
             return false;
         }
         return true;
     }
 });

(mMultiTouchController is the class containing all my gesture detection code). The key here is within this class, I added the bool 'has_moved'. When I go to start a drag I then compute the delta:

 float diffX = Math.abs(mCurrPtX - mPrevPt.getX());
 float diffY = Math.abs(mCurrPtY - mPrevPt.getY());
 if (diffX < threshold && diffY < threshold) {
     has_moved = false;
     return;
 }

Now when the onLongClick fires I know whether to take action or not.

The final piece was to set:

setHapticFeedbackEnabled(false);

in my View so that the user doesn't get a vibrate every time the longClick fires but no action is taken. I plan to do the vibration manually as a next step.

This seems to be ok so far, hope that helps anyone who has come across a similar situation as this one.
