Android实现RecyclerView侧滑删除和长按拖拽

在你会使用recyclerView前提下：

1,在Activity里面添加如下代码：

////////////////////定义一个heleper对象并且在其内部实现如下方法///////////////////
ItemTouchHelper helper = new ItemTouchHelper(new ItemTouchHelper.Callback() {
    @Override
    public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
        //首先回调的方法 返回int表示是否监听该方向
        int dragFlags = ItemTouchHelper.UP|ItemTouchHelper.DOWN;//拖拽
        int swipeFlags = ItemTouchHelper.LEFT|ItemTouchHelper.RIGHT;//侧滑删除
        return makeMovementFlags(dragFlags,swipeFlags);
    }
    @Override
    public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
        //滑动事件
        Collections.swap(lists,viewHolder.getAdapterPosition(),target.getAdapterPosition());
        cententMessageAdata.notifyItemMoved(viewHolder.getAdapterPosition(),target.getAdapterPosition());
        return false;
    }

    @Override
    public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {
        //侧滑事件
        lists.remove(viewHolder.getAdapterPosition());
        cententMessageAdata.notifyItemRemoved(viewHolder.getAdapterPosition());//cententMessageAdata是你的适配器
    }

    @Override
    public boolean isLongPressDragEnabled() {
        //是否可拖拽
        return true;
    }

});

2,然后在

recyclerView.setAdapter(cententMessageAdata);

后面加上

helper.attachToRecyclerView(recyclerView);

就可以了
