android: one item swipe at a time in recyclerview

Question

I am implementing endless recyclerView and using this library for swipe. I am facing the problem in which more than one item is swipe in recyclerview at a time. If I drag second view of recyclerview and if first view is open then it should be hide means only one item in recyclerview show the same time. Below is my adapter

    public class Adapter<T> extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private final int VIEW_ITEM = 1;
    private final int VIEW_PROG = 0;
    private List<MyModel> mDataset;

    // The minimum amount of items to have below your current scroll position before loading more.
    private int visibleThreshold = 2;
    private int lastVisibleItem, totalItemCount;
    private boolean loading;
    private OnLoadMoreListener onLoadMoreListener;

    private Context context;

    public Adapter(List<MyModel> myDataSet, RecyclerView recyclerView) {
        mDataset = myDataSet;

        if (recyclerView.getLayoutManager() instanceof LinearLayoutManager) {

            final LinearLayoutManager linearLayoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();
            recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                    super.onScrolled(recyclerView, dx, dy);

                    totalItemCount = linearLayoutManager.getItemCount();
                    lastVisibleItem = linearLayoutManager.findLastVisibleItemPosition();
                    if (!loading && totalItemCount <= (lastVisibleItem + visibleThreshold)) {
                        // End has been reached
                        // Do something
                        if (onLoadMoreListener != null) {
                            onLoadMoreListener.onLoadMore();
                        }
                        loading = true;
                    }
                }
            });
        }
    }

    @Override
    public int getItemViewType(int position) {
        return mDataset.get(position) != null ? VIEW_ITEM : VIEW_PROG;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        RecyclerView.ViewHolder vh;
        if (viewType == VIEW_ITEM) {
            View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.movie_list_row, parent, false);

            vh = new TextViewHolder(itemView);
        } else {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.progressbar_item, parent, false);
            vh = new ProgressViewHolder(v);
        }
        return vh;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        if (holder instanceof TextViewHolder) {
            MyModel model = mDataset.get(position);

            ((TextViewHolder) holder).tvFname.setText(model.getStrFname());
            ((TextViewHolder) holder).tvLname.setText(model.getStrLname());

//            SwipeItemRecyclerMangerImpl mItemManger = new SwipeItemRecyclerMangerImpl(Adapter.this);
//            mItemManger.bindView(holder.itemView, position);
        }

        else {
            ((ProgressViewHolder) holder).progressBar.setIndeterminate(true);
        }
    }

    public void setLoaded() {
        loading = false;
    }

    @Override
    public int getItemCount() {
        return mDataset.size();
    }

    public void setOnLoadMoreListener(OnLoadMoreListener onLoadMoreListener) {
        this.onLoadMoreListener = onLoadMoreListener;
    }

    public interface OnLoadMoreListener {
        void onLoadMore();
    }

    public static class TextViewHolder extends RecyclerView.ViewHolder {
        public TextView tvFname, tvLname;

        public TextViewHolder(View v) {
            super(v);

            tvFname = (TextView) v.findViewById(R.id.tvName);
            tvLname = (TextView) v.findViewById(R.id.tvEmailId);
        }
    }

    public static class ProgressViewHolder extends RecyclerView.ViewHolder {
        public ProgressBar progressBar;

        public ProgressViewHolder(View v) {
            super(v);
            progressBar = (ProgressBar) v.findViewById(R.id.progressBar);
        }
    }
}

Here is my MainActivity.

    public class MainActivity extends AppCompatActivity {

    private RecyclerView mRecyclerView;
    public SearchView search;
    private ArrayList<MyModel> arrayList  = new ArrayList<MyModel>();
    private Adapter mAdapter;
    protected Handler handler;
    private MyModel model;
    int test=1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        setRecycler();
    }

    private void setRecycler() {

        RecyclerView mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        createlist();  // in this method, Create a list of items.
        mRecyclerView.setHasFixedSize(true);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        //add devider to recycleview.
        mRecyclerView.addItemDecoration(new SimpleDividerItemDecoration(getApplicationContext()));

        mAdapter = new Adapter(arrayList, mRecyclerView);
        mRecyclerView.setAdapter(mAdapter);
        handler = new Handler();

        mAdapter.setOnLoadMoreListener(new Adapter.OnLoadMoreListener() {
            @Override
            public void onLoadMore() {
                //add progress item
                arrayList.add(null);
                mAdapter.notifyItemInserted(arrayList.size() - 1);

                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        //remove progress item
                        arrayList.remove(arrayList.size() - 1);
                        mAdapter.notifyItemRemoved(arrayList.size());
                        //add items one by one
//                            arrayList.add("Item " + (arrayList.size() + 1));
                        createlist();

                        mAdapter.notifyItemInserted(arrayList.size());
                        mAdapter.setLoaded();
                        //or you can add all at once but do not forget to call mAdapter.notifyDataSetChanged();
                    }
                }, 2000);
                System.out.println("load");
            }
        });
    }

    // this method is used to create list of items.
    public void createlist() {
        for (int i = 1; i <= 20; i++) {
            model = new MyModel();
            model.setStrFname("Testing"+test);
            model.setStrLname("Testing"+i+"@gmail.com");
            arrayList.add(model);
            test++;
        }
    }

}
