```
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {

    private ArrayList<ModuleViewModel> items =  new ArrayList<>();
    private OnItemCheckListener onItemClick;
    private Context mContext;

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.item_modules_list, parent, false);

        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
        final ModuleViewModel currentItem = items.get(position);
        holder.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                    holder.checkbox.setChecked(
                            ! holder.checkbox.isChecked());
                    if ( holder.checkbox.isChecked()) {
                        onItemClick.onItemChecked(currentItem);
                    } else {
                        onItemClick.onItemUnchecked(currentItem);
                    }
            }
        });
    }

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

    public interface OnItemCheckListener {
        void onItemChecked(ModuleViewModel item);
        void onItemUnchecked(ModuleViewModel item);
    }

    public MyAdapter (Context context,ArrayList<ModuleViewModel> items, @NonNull OnItemCheckListener onItemCheckListener) {
        this.mContext = context;
        this.items = items;
        this.onItemClick = onItemCheckListener;
    }

    static class MyViewHolder extends RecyclerView.ViewHolder {
        CheckBox checkbox;
        View itemView;

        public MyViewHolder(View itemView) {
            super(itemView);
            this.itemView = itemView;
            checkbox = (CheckBox) itemView.findViewById(R.id.uiCkbModule);
            checkbox.setClickable(false);

        }

        public void setOnClickListener(View.OnClickListener onClickListener) {
            itemView.setOnClickListener(onClickListener);
        }
    }
}

```

This is My Adapter calling Code

```
mModuleListAdapter = new ModuleListAdapter(mContext, mModuleListModel, this);
 mRvModuleView.setAdapter(mModuleListAdapter);

```
