public class SuggestionListAdapter extends RecyclerView.Adapter {

private List mSuggestionList;
private Context mContext;



public class SuggestionListViewHolder extends RecyclerView.ViewHolder{
    private CheckBox mCheckBox;
    private LinearLayout mParent;


    public SuggestionListViewHolder(View itemView) {
        super(itemView);
        mCheckBox = (CheckBox)itemView.findViewById(R.id.list_display_checkbox);
        mParent =(LinearLayout)itemView.findViewById(R.id.list_parentll);
    }
}

public SuggestionListAdapter(List suggestionList, Context context) {
    this.mSuggestionList = suggestionList;
    this.mContext = context;
}

@Override
public SuggestionListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View new_suggestion_list_view = LayoutInflater.from(parent.getContext()).inflate(R.layout.suggestion_list,parent,false);
    return new SuggestionListViewHolder(new_suggestion_list_view);
}
@Override
public void onBindViewHolder(final SuggestionListViewHolder holder, final int position) {

    final Suggestion suggestion = mSuggestionList.get(position);

    holder.mCheckBox.setText(suggestion.getCategory());
    holder.mCheckBox.setOnCheckedChangeListener(null);
    holder.mCheckBox.setSelected(suggestion.isSelected());
    holder.mCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked){
                suggestion.setSelected(true);
            }else {
                suggestion.setSelected(false);
            }
        }
    });
    holder.mCheckBox.setChecked(suggestion.isSelected());
}

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