Как правильно использовать фрагменты

Question

Я пытаюсь научиться использовать Фрагменты в android. Я создаю отдельные классы и макеты. У меня возникли проблемы с пониманием того, как я должен связывать их все. Что именно происходит в моем основном классе? Может кто-нибудь, пожалуйста, продемонстрировать, как использовать фрагменты очень простым способом?

Answer 1

В вашем основном классе вы производите один или несколько фрагментов ... Пока вы производите каждый фрагмент, он очень похож на Activity, но имеет свой собственный жизненный цикл (google it).

вот пример на фрагменте:

public class DummySectionFragment3 extends Fragment 
{ 
    public DummySectionFragment3() { 
    } 

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

     View rootView = inflater.inflate(R.layout.exercise_layout, 
       container, false); 
     return rootView; 
    } 
} 

в OnCreateView() метод вы делаете то, что вы обычно делаете с деятельностью. Мой главный класс содержит разделы PagerAdapter, который переключается между фрагментами (пейджер, как в примерах API) создайте 2 или 3 фрагмента и просто попробуйте его ... Я не нашел на нем хороших примеров, поэтому я просто попробовал выше ,

Answer 2

Я использовал эту ссылку, чтобы начать http://www.techotopia.com/index.php/Using_Fragments_in_Android_-_A_Worked_Example

Этот парень использует 2 различных типов слушателей и принимает во входных данных пользователя на первом фрагменте. Второй фрагмент выводит данные!

Goodluck!

Вот одна хорошая связь с закладками и фрагментов. Вы также можете определить свои фрагменты в своем xml.

Answer 4

Основной, как это:

Создать одну активность и 2 фрагментов.

Если что-то происходит в FragmantA, то что-то должно измениться в фрагменте справа. Таким образом, активность связывает фрагменты A и B вместе. Что вам нужно для этого: интерфейс.

Создайте интерфейс с помощью метода, который принимает правильные свойства (не забудьте тип данных). Теперь вы можете реализовать интерфейс в своей деятельности.

После этого вы должны инициализировать интерфейс в FragmentA в методе onActivityCreated. Выполните изменения и отправьте данные в интерфейсный метод в Activity. Создайте ссылку на FragmentB с помощью FragmentManager. Теперь вы можете отправить данные/изменения в FragmentB.

Надеюсь, вы это поняли;). ура

Answer 5

, пожалуйста, прочитайте this сначала как, я думаю, у меня есть самые основы. Ниже приведен пример:

MainActivity:

public class MainActivity extends Activity implements OnClickListener{ 

private final String TAG = "MainActivity"; 
private int btn00Clicks = 0; 
private int btn01Clicks = 0; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.mainactivity); 
} 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    Fragment mSelectedFragment = null; 

    switch (v.getId()) { 
    case R.id.btn00:  
     Bundle mBundle00 = new Bundle(); 
     String clicks00 = Integer.toString(btn00Clicks); 
     mBundle00.putString("btn00_clicks", clicks00); 
     mSelectedFragment = new Fragment00(); 
     mSelectedFragment.setArguments(mBundle00); 

     if (mSelectedFragment != null) { 
      FragmentManager mFragmentManager = getFragmentManager(); 
      mFragmentManager.beginTransaction() 
      .replace(R.id.fragment00ID, mSelectedFragment).commit(); 
     } 
     btn00Clicks++; 

     break; 
    case R.id.btn01:  
     Bundle mBundle01 = new Bundle(); 
     String clicks01 = Integer.toString(btn01Clicks); 
     mBundle01.putString("btn01_clicks", clicks01); 
     mSelectedFragment = new Fragment01(); 
     mSelectedFragment.setArguments(mBundle01); 

     if (mSelectedFragment != null) { 
      FragmentManager mFragmentManager = getFragmentManager(); 
      mFragmentManager.beginTransaction() 
      .replace(R.id.fragment00ID, mSelectedFragment).commit(); 
     } 
     btn01Clicks++; 
    } 
} 

}

Fragment00.java:

public class Fragment00 extends Fragment { 

private final String TAG = "Fragment00"; 
TextView mTv; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    View view = inflater.inflate(R.layout.fragment00, null); 
    return view; 
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onActivityCreated(savedInstanceState); 

    mTv = (TextView) getView().findViewById(R.id.fragment00Tv00); 

    if (getArguments() != null) { 
     String str = getArguments().getString("btn00_clicks").toString(); 
     mTv.setText("the Button was clicked "+str+ " time(s)"); 
     Log.i(TAG, "onActivityCreated(): "+str); 
    }else { 
     Log.i(TAG, "onActivityCreated(): getArguments() is NULL"); 
    } 
} 

@Override 
public void onAttach(Activity activity) { 
    // TODO Auto-generated method stub 
    super.onAttach(activity); 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
} 

}

Fragment01.Java:

public class Fragment01 extends Fragment { 

private static final String TAG = "Fragment01"; 
TextView mTv; 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    return inflater.inflate(R.layout.fragment01, null); 
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onActivityCreated(savedInstanceState); 

    mTv = (TextView) getView().findViewById(R.id.fragment01Tv00); 

    if (getArguments() != null) { 
     String str = getArguments().getString("btn01_clicks").toString(); 
     mTv.setText("the Button was clicked "+str+ " time(s)"); 
     Log.i(TAG, "onActivityCreated(): "+str); 
    }else { 
     Log.i(TAG, "onActivityCreated(): getArguments() is NULL"); 
    } 
} 

}

Answer 6

Я сделал образец проекта, который не делает использование ViewPager и все странные вещи, только связь между Activity и Fragment здесь на Stack Overflow и тот же вещь на Code Review, чтобы продемонстрировать это, щелкните по ссылкам, чтобы увидеть проект.
