Custom RecyclerView supporting ContextMenu & ContextMenuInfo

/**

public class ContextMenuRecyclerView extends RecyclerView {

    private ContextMenu.ContextMenuInfo mContextMenuInfo;

    public ContextMenuRecyclerView(Context context) {
        super(context);
    }

    public ContextMenuRecyclerView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ContextMenuRecyclerView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override

    }

    /**

     */
    public void openContextMenu(int position) {
        if (position >= 0) {

        }
        showContextMenu();
    }


    ContextMenu.ContextMenuInfo createContextMenuInfo(int position, long id) {
        return new RecyclerContextMenuInfo(position, id);
    }

    /**
     * Extra menu information provided to the {@link android.view.View
     * .OnCreateContextMenuListener#onCreateContextMenu(android.view.ContextMenu, View,
     * ContextMenuInfo) } callback when a context menu is brought up for this RecycleView.
     */
    public static class RecyclerContextMenuInfo implements ContextMenu.ContextMenuInfo {

        /**
         * The position in the adapter for which the context menu is being displayed.
         */
        public int position;

        /**
         * The row id of the item for which the context menu is being displayed.
         */
        public long id;

        public RecyclerContextMenuInfo(int position, long id) {
            this.position = position;
            this.id = id;
        }
    }

}

you can use it in the same way by passing your RecyclerView to:
registerForContextMenu(myRecyclerView);

And when ever your menu item click happens on recycler view: myRecyclerView.openContextMenu(clickedItemPosition);

To use the menuInfo object:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo
        menuInfo) {
    super.onCreateContextMenu(menu, view, menuInfo);

    ContextMenuRecyclerView.RecyclerContextMenuInfo info = (ContextMenuRecyclerView
            .RecyclerContextMenuInfo) menuInfo;
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    ContextMenuRecyclerView.RecyclerContextMenuInfo info = (ContextMenuRecyclerView
            .RecyclerContextMenuInfo) item
            .getMenuInfo();
}

hello
can you please provide some demo for this. It will be really helpfull.

Thanks
