Как очистить все значения в RecyclerView

Question

EveryThing работает с представлением Recycler. Но проблема в том, что кнопка «Очистить» внизу, я хочу использовать эту кнопку, чтобы очистить все выбранное, но на данный момент, если я выберу 59, а затем нажмите «Очистить», 05 будет получить автоматический выбор, и когда я снова нажимаю очистить, он очищается. Еще одна вещь recylcerView не отображает макет точно по центру. Я отрегулировал его, используя поля, есть ли способ сделать это правильно.

PickNumberPojo

    }

    public String getText() {
        return (text < 10 ? "0" + text : String.valueOf(text));
    }

    public void setText(int text) {
        this.text = text;
    }

    public boolean isChecked() {
        return isChecked;

    public void setChecked(boolean checked) {
