Преобразование старой активности в фрагмент

Я хочу использовать ящик навигации для перечисления своих действий, но вы должны использовать фрагменты с ящиком, чтобы я хотел преобразовать свою старую активность в фрагмент.Преобразование старой активности в фрагмент

Не уверен, если я должен продлить фрагмент или FragmentActivity, а также, где я вставить все мои компоненты пользовательского интерфейса, такие как панель инструментов т.д ..

Активность скатывается язычки с ListView

Создать активность который расширяет FragmentActivity и в FragmentActivity вы можете вставлять код навигационного ящика и повторно используемые компоненты.

Вы должны расширить фрагмент из поддержки v4. И вы инициализируете свои представления в методе onCreateView.

import android.support.v4.app.Fragment; 

public class SkillsPsFragment extends Fragment { 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 


    View root = inflater.inflate(R.layout.activity_skills_ps, container, false); 

    Toolbar toolbar = (Toolbar) root.findViewById(R.id.toolbar); 
    //repeat this for all views 

    return root: 
}

Чтобы использовать фрагмент, который вы можете иметь базовую деятельность с макетом XML как так

<FrameLayout 
     android:id="@+id/maincontainer" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" />

, а затем в конце вашего метода Деятельность OnCreate использовать это, чтобы показать этот фрагмент

getSupportFragmentManager().beginTransaction() 
       .replace(R.id.maincontainer, new SkillsPsFragment(), "TAG") 
       .commit();
