Я пытаюсь изменить код, написанный com.divyeshbc, который я вытащил из GitHub. Исходный код устанавливает панель инструментов в main_activity и заполняет ее значками. Я хочу перекомпоновать этот код как отдельный класс, чтобы я мог открыть панель инструментов в качестве диалога, когда я нажимаю кнопку. У меня две проблемы.Сбой панели инструментов Android
1: Тип «android.support.v7.widget.Toolbar» не распознается так же, как «Панель инструментов». Мне нужно использовать все переменные специально для findViewById(). Сбой происходит в SlidingTab.initialize(), в «findViewById (R.id.toolbar)». Поиск не работает, и программа вылетает из строя.
2: (Панель инструментов) FindViewById (R.id.toolbar) отлично работает в main_activity, но не в методе, вызванном из основного действия. Я попытался заставить setContentView() к представлению, которое, как я знаю, содержит идентификатор, но он не помогает. Когда сбой поиска завершится, программа выйдет из строя.
Я использую последнюю версию Android IDE (1.5, я думаю) и последний SDK. Я застрял - я был бы признателен за любые советы и предложения.

Я не могу StackOverflow принять последний бит кода стиля. Если это важно, я найду способ опубликовать его. Это всего лишь несколько строк, определяющих Titletext, цвет и размер шрифта.
Нам нужен код на 95% меньше и вывод логарифма. – csmckelvey
