Почему эта ошибка показывает «Несовместимые типы». «Обязательно: android.support.v4.app.Fragment»?

Question

Так что мой вопрос с моей Android приложений Фрагменты fragment=new SlideShow(); находится в коммутаторе, это Fuctions в NavDrawer и эти люди имели один и тот же вопрос, но ни один из этих решений не фиксированная моя проблема Solution 1 и Solution 2 также Solution 3

Вы можете увидеть что-то в кода, которого у меня нет. Я сделаю ошибку, как она показывает!

Я попытался добавить импорт, а также переключить орудия и продолжит работу, ничего не сработало и никто с той же проблемой, что и mien.

Ошибка:

Error:(176, 26) error: incompatible types: SlideShow cannot be converted to Fragment

и

Incompatible Types. Required: android.support.v4.app.Fragment Found: com.adobe.SlideShow

Мой код сниппета:

Answer 1

слайд-шоу является активность не Fragment. Вам нужно будет воссоздать его как фрагмент или использовать намерение переключиться на него. Вы могли бы сделать что-то наподобие:

case 0: 
    Intent intent = new Intent(this, Slideshow.class); 
    startActivity(intent); 
    return;
