Fling to remove sensitivity

[cucko]

Is there a way to set/change 'fling to remove' sensitivity (probably velocity check). i have listview where both drag to sort, and fling to remove are enabled. but almost 50% it removes the items instead of scroll the list. thanks for your great library.

hm, its not that. my issue is that when user want to scroll the list, if he does a little angled move (not straight vertical), there is a very good chance that the motion is detected as fling/remove and removes the item instead of scrolling the list.

@cucko , find the method in DragSortController.java, and try to make mTouchSlop BIGGER.

public DragSortController(DragSortListView dslv, int dragHandleId,
        int dragInitMode, int removeMode, int clickRemoveId,
        int flingHandleId) {
    super(dslv);
    mDslv = dslv;
    mDetector = new GestureDetector(dslv.getContext(), this);
    mFlingRemoveDetector = new GestureDetector(dslv.getContext(),
            mFlingRemoveListener);
    mFlingRemoveDetector.setIsLongpressEnabled(false);
    mTouchSlop = ViewConfiguration.get(dslv.getContext())
            .getScaledTouchSlop(); // ***to slow down the fling, you could set [mTouchSlop *= 4;]***
    mDragHandleId = dragHandleId;
    mClickRemoveId = clickRemoveId;
    mFlingHandleId = flingHandleId;
    setRemoveMode(removeMode);
    setDragInitMode(dragInitMode);
}

@bullda thank you, that's exactly what i was looking for.

FYI, I've found a good way to make the sensitivity better (at least for my uses). Basically I found that when I scroll the list sometimes the item would get flinged off. To solve this I adjusted the onScroll method in DragSortController to only fling if the horizontal difference was greater than 2 times the vertical difference. That is, make sure that the user isn't dragging more vertically than horizontally before flinging. Code:

} else if (mFlingHitPos != MISS) { if (Math.abs(x2 - x1) > mTouchSlop && mRemoveEnabled /\ I added this to the conditional */ && Math.abs(x2 - x1) > 2 \ Math.abs(y2 - y1)) { mIsRemoving = true; startDrag(mFlingHitPos, deltaX, deltaY); } else if (Math.abs(y2 - y1) > mTouchSlop) { mCanDrag = false; // if started to scroll the list then // don't allow sorting nor fling-removing } }

Thank you very much. The solution is very useful.

Black tiger's solution is best, thanks a lot
