How to stop swipe at some point in ItemTouchHelpers?

I need to swipe an item at the beginning, or did a full swipe, or stopped in current point. As in the Yandex mail. I was tring to do setLeft(dx) and setRight(dx) but that's not what I need

I have class

ItemTouchHelperCallback extends ItemTouchHelper.Callback 

and inside i override method

@Override
public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
    View itemView = viewHolder.itemView;

    // not sure why, but this method get's called for viewholder that are already swiped away
    if (viewHolder.getAdapterPosition() == -1) {
        // not interested in those
        return;
    }

    float height = (float) itemView.getBottom() - (float) itemView.getTop();
    float width = height / 3;
    float temdX=0;
    Bitmap icon;
    if(dX > 0 || lastdX>0){

        //try stop item while back in dx=0, but workin only while i debug
        if(lastdX>=100 && dX==0 &&lastdX!=0 &&lastdX!=-720)
        {
            dX=100;
            isCurrentlyActive=true;

        }
        lastdX=dX;
        itemView.setLeft((int) dX);
        p.setColor(Color.GREEN);
        RectF background = new RectF((float) itemView.getLeft(), (float) itemView.getTop(), dX,(float) itemView.getBottom());
        c.drawRect(background,p);
        icon = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.ic_y);
        RectF icon_dest = new RectF((float) itemView.getLeft() + width ,(float) itemView.getTop() + width, (float) itemView.getLeft()+ 2*width,(float)itemView.getBottom() - width);
        c.drawBitmap(icon, null, icon_dest, p);


    } else if(lastdX<0 || dX<0) {
        if(lastdX<=-100 && dX==0 &&lastdX!=0 &&lastdX!=720)
        {
            dX=-100;
            //itemView.setTranslationX(-200);

            isCurrentlyActive=true;
        }
        lastdX=dX;
        itemView.setRight((int)(dX));
        p.setColor(Color.RED);
        RectF background = new RectF((float) itemView.getRight() + dX, (float) itemView.getTop(),(float) itemView.getRight(), (float) itemView.getBottom());
        c.drawRect(background,p);

        icon = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.ic_x);
        RectF icon_dest = new RectF((float) itemView.getRight() - 2*width ,(float) itemView.getTop() + width, (float) itemView.getRight() - width,(float)itemView.getBottom() - width);
        c.drawBitmap(icon,null,icon_dest,p);

    }
    super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}
