can't insert checkbox value in sqlite database on android

I have a recyclerview with some items and checkbox include. I know, that can`t use boolean type in sqlite, so Iuse INTEGER (true = 1, false = 0). By default - false. When i tick on checkbox , I want to insert '1', else '0'.

My model class

public class Task {
    private long mId;
    private String mTitle;
    private String mDesc;
    private String mDate;
    private String mSolved;
    private String mTime;

//getters and setters... }

holder

public class TaskHolder extends RecyclerView.ViewHolder{
    @BindView(R.id.tvTitle)
    TextView title;
    @BindView(R.id.tvDesc)
    TextView desc;
    @BindView(R.id.tvDate)
    TextView date;
    @BindView(R.id.tvTime)
    TextView time;
    @BindView(R.id.cbIsSolved)
    CheckBox isSolved;

    public TaskHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this,itemView);
    }

    public void bindTaskHolder(final Task task){
        title.setText(task.getmTitle());
        date.setText(task.getmDate());
        time.setText(task.getmTime());
        desc.setText(task.getmDesc());
        isSolved.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

       @Override
        public void onCheckedChanged(CompoundButton arg0, boolean checked) {
            // TODO Auto-generated method stub
            if(checked)
            {
                task.setmSolved("1");
            }
            else
            {
                task.setmSolved("0");
            }
        }
    });
    }
}

and myadapter

public class TaskAdapter extends RecyclerViewTaskCursorAdapter<TaskHolder> {
public TaskAdapter(Context context, Cursor cursor) {
    super(context, cursor);
}

@Override
public TaskHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_tasklist, parent, false);
    return new TaskHolder(view);
}

@Override
public void onBindViewHolder(TaskHolder viewHolder, Cursor cursor) {
    long id = cursor.getLong(cursor.getColumnIndex(DatabaseHelper.ID_TASK));
    String title = cursor.getString(cursor.getColumnIndex(DatabaseHelper.TITLE_TASK));
    String desc = cursor.getString(cursor.getColumnIndex(DatabaseHelper.DESCRIPTION_TASK));
    String date = cursor.getString(cursor.getColumnIndex(DatabaseHelper.DATE_TASK));
    String time = cursor.getString(cursor.getColumnIndex(DatabaseHelper.TIME_TASK));
    String solved = (cursor.getString(cursor.getColumnIndex(DatabaseHelper.IS_SOLVED_TASK)));

    Task task = new Task();
    task.setmId(id);
    task.setmTitle(title);
    task.setmDesc(desc);
    task.setmDate(date);
    task.setmTime(time);
    task.setmSolved(solved);

    viewHolder.bindTaskHolder(task);
}

}
