Как переключиться с фрагмента на фрагментАктивность на активность в android

Question

У меня есть класс фрагмента, в котором у меня есть несколько вкладок фрагментов. каждый из них открывает другой выделенный фрагмент. но я хочу изменить один фрагмент, чтобы открыть класс активности. Я прошел множество примеров, но проблема не решена. каждый раз мое приложение разбивается.

вот мой класс фрагментов.

Я хочу Настройка вкладку, чтобы открыть новый вид деятельности не фрагментировать, который Настройки2

вот мой класс активности, что я должен открыть

импорта android.app.Activity; import android.os.Bundle;

общественный класс Настройки2 расширяет активность {

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.setting2); 

} 

}

Answer 1

Шаг 1 - объявить активность внутри manifest
Шаг 2
- starActivity(new Intent(getAcivity(), MyClass.class));
Шаг 3
- разместите свой логарифм, если это не помогло, пока он должен!
Редактировать: проблема заключается в том, что вы не устанавливаете высоту для своих макетов, основываясь на своем макете, который вы опубликовали, у вас есть пять макетов, которые отсутствуют android:layout_height, пожалуйста, добавьте это, и сила закрытия исчезнет.
