Try this,it worked with me in my app,

In your adapter class put this below code,

here MessageList is name of the Arraylist,

public void swap(int firstPosition, int secondPosition)
{
    Collections.swap(MessageList, firstPosition, secondPosition);
    notifyItemMoved(firstPosition, secondPosition);
}

now add this small class separately,

here Adapter is name of the Adapter class put your adapter name

public class MovieTouchHelper extends ItemTouchHelper.SimpleCallback {
    Aadapter recycleAdapter;

    public MovieTouchHelper(Aadapter recycleAdapter) {
        super(ItemTouchHelper.UP | ItemTouchHelper.DOWN, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT);
        this.recycleAdapter = recycleAdapter;
    }

    @Override
    public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
        recycleAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
        return true;
    }

    @Override
    public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {
        recycleAdapter.remove(viewHolder.getAdapterPosition());
    }
}

Then in your mainActivity where you defined recycleview,

ItemTouchHelper.Callback callback = new MovieTouchHelper(adapter);
ItemTouchHelper helper = new ItemTouchHelper(callback);
helper.attachToRecyclerView(rv_list);

here rv_list is name of recycleview.

Follow this steps and if you find any problem or you can't swip items then directly tell me...

You can use the following links:

https://github.com/cymcsg/UltimateRecyclerView

https://github.com/wasabeef/recyclerview-animators

use any one of this. I hope it will help you.

Import the lib in your project.

You should use the ItemTouchHelper from the RecyclerView.ItemDecoration class. I just accomplish the behavior you're willing by following this tutorial: https://medium.com/@ipaulpro/drag-and-swipe-with-recyclerview-b9456d2b1aaf#.p6vykzstq
