平日工作日的Android日历

Question

如何在recyclerview中使用水平滚动获得工作日？

 RecyclerView recyclerView = (RecyclerView) findViewById(R.id.widget_list);
        adapter = new MyAdapter(this,getList());
        LinearLayoutManager horizontalLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.HORIZONTAL, false);
        recyclerView.setLayoutManager(horizontalLayoutManager);
        recyclerView.setAdapter(adapter);   
        recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            if (isMultiSelect){
                //if multiple selection is enabled then select item on single click else perform normal click on item.
                multiSelect(position);
            }
        }

        @Override
        public void onItemLongClick(View view, int position) {
            if (!isMultiSelect){
                selectedIds = new ArrayList<>();
                isMultiSelect = true;

                if (actionMode == null){
                    actionMode = startActionMode(MainActivity.this); //show ActionMode.
                }
            }

            multiSelect(position);
        }
    }));
}
private void multiSelect(int position) {
    MyData data = adapter.getItem(position);
    if (data != null){
        if (actionMode != null) {
            if (selectedIds.contains(data.getId()))
                selectedIds.remove(Integer.valueOf(data.getId()));
            else
                selectedIds.add(data.getId());

            if (selectedIds.size() > 0)
                actionMode.setTitle(String.valueOf(selectedIds.size())); //show selected item count on action mode.
            else{
                actionMode.setTitle(""); //remove item count from action mode.
                actionMode.finish(); //hide action mode.
            }
            adapter.setSelectedIds(selectedIds);

        }
    }
}
