Пользовательский вид списка выдвижных ящиков для навигации

Question

Привет, я новичок в мире Android, и я создал ящик для навигации с шаблоном по умолчанию в студии android. Я ищу способ сделать раздел в моем списке таким:! [Enter описание изображения здесь] [1]

Как я хочу, чтобы мой ListView быть: https://camo.githubusercontent.com/7043b4240e1be50bb68b3f101c1f9815c9be0f11/68747470733a2f2f7261772e6769746875622e636f6d2f6e656f6b7265652f4d6174657269616c4e617669676174696f6e4472617765722f6d61737465722f73637265656e312e6a7067

Вот код моего фрагмента, я действительно не знаю, как это сделать, и я хочу, чтобы иметь изображение на наверху с электронной почтой, как фотография с двумя разделами:

public class NavigationDrawerFragment extends Fragment { 


    private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position"; 


    private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";

    private ActionBarDrawerToggle mDrawerToggle; 

    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerListView; 
    private View mFragmentContainerView; 

    private int mCurrentSelectedPosition = 0;

} 

i нужно закончить это на следующей неделе, потому что это проект в школе :(

Answer 1

Вы можете настроить навигационный ящик с подходящим расположением. Вы можете раздуть любую компоновку в ящике и сделать правильную логику для реализации.

Вам необходимо изменить метод

onCreateView();

Для конкретного макета можно изменить, как -

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     View rootView= inflater.inflate(
       R.layout.fragment_navigation_drawer_layout, container, false); 

     return rootView; 
    } 

Здесь

fragment_navigation_drawer_layout 

является расположение вы хотите установить.
