Enable Dragging on only Long Click

[Raminishekhar]

enabling drag on long click is not available and no callback method for ondragstop.

I found a simple solution to this.

1. Add a boolean to DragLinearLayout

static boolean canDrag = false

2. In setViewDraggable, add an onLongClickListener to the new view that simply does

dragHandle.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
canDrag = true;
return false;
}
});

3. Replace all instances of startDrag() with:

if (canDrag) {
startDrag();
return true;
}

4. In startDrag() AND onTouchEnd() add

canDrag = false

Basically, if the view being touched has also been long clicked then carry out activities as normal. I also removed the slop check in ACTION_MOVE because it was extremely difficult to do.

Sorry about the formatting. I made an account to write this comment.
