Приложение вылетает. Не могу полностью понять в чем проблема. В logcat пишет:

Также добавляю DialogAdapter.java, думаю он пригодится:

    void onDoubleClick();
}

    this.mFieldTexts = fields;
    this.mFieldHeaders = fieldHeaders;

    return new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.rustate_dialog_item, parent, false));

    onBindViewHolder((ViewHolder) holder, position);

        TextView field = holder.mFields.get(i);
        field.setText(Utils.transfromColors(headers[i].replace("\\t", "")));
        field.setVisibility(View.VISIBLE);

public void setOnClickListener(OnClickListener onClickListener) {

Index: 4, Size: 4

Это означает, в массиве 4 элемента. Индексация элементов в массивах начинается с нуля (0). Соответственно, индекс Вашего первого элемента "0", а индекс последного четвертого элемента "3".

length хранит в себе количество элементов. (В вашем случае 4 элемента)

Когда вы просите элемента с 4им индексом (его там нет, у четвертого элекмента индекс: 3) java выбрасывает исключение.

РЕШЕНИЕ: Сделайте "length-1" в цикле!

Причину нашел! Проблема была в mHeadersLayout, тоесть там в самом лайоте создавалось 4 строки, когда в моем диалоге должно быть 5! Добавил строку, проблема решена! решил проблему над которой работал пол дня
