如何限制onSwiped（）忽略一个方向？

Question

我有一个onSwiped（）在向右滑动而不向左滑动时做了必要的事情，问题是它仍然滑动，我希望它能够＆＃34;冻结＆＃34;当向左滑动时。

 ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new ItemTouchHelper.SimpleCallback(ItemTouchHelper.START | ItemTouchHelper.END,
                ItemTouchHelper.START | ItemTouchHelper.END) {
                @Override
                 public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
                return false;
            }
            @Override
            public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {

                Log.d(TAG, "whats swiped " + viewHolder.getAdapterPosition() + "   direction: " + direction + "   arrayListCountyNames.get(viewHolder.getAdapterPosition())" + arrayListCountyNames.get(viewHolder.getAdapterPosition()));
                if (direction==16) {//do something}

创建ItemTouchHepler.RIGHT时，您应该将ItemTouchHelper.SimpleCallback作为第二个参数传递：

ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new ItemTouchHelper.SimpleCallback(ItemTouchHelper.START | ItemTouchHelper.END,
            ItemTouchHelper.RIGHT));
