Essayer de passer une intention d'un SherlockFragment à SherlockFragment

Question

Je veux passer une intention de mon SherlockActivity à mon SherlockFragment mais je ne comprends pas comment faire cela. Je veux passer le CategoryID dans MaterialsActivity à BooksFragment ci-dessous. Le code de l'MaterialActivity est ci-dessous et à l'extrémité lointaine le BooksFragment est collé.

 public class MaterialsActivity extends SherlockFragmentActivity{ 

     String categoryID = null; 
     Context context = null; 
     Resources resources = null; 

     IDatabaseHelper databaseHelper = null; 

     // store the active tab here 
      public static String ACTIVE_TAB = "activeTab"; 

      //Initializing the Tab Fragments that would be added to this view 
      AudiosFragment audioFragment = null; 
      BooksFragment bookFragment = null; 
      VideosFragment videoFragment = null; 

     @Override 
     public void onCreate(Bundle savedInstanceState){ 
      super.onCreate(savedInstanceState); 
      //setContentView(R.layout.materials); 

      Intent intent = getIntent(); 

      categoryID = intent.getExtras().getString("categoryID"); 

      context = MaterialsActivity.this; 
      resources = getResources(); 

      databaseHelper = new DatabaseHelper(context); 


      final ActionBar actionBar = getSupportActionBar(); 
      actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 
      // add tabs 
      Tab tab1 = actionBar.newTab() 
         .setText("Books") 
         .setTabListener(new BooksListener<BooksFragment>(
         this, "book", BooksFragment.class)); 
      actionBar.addTab(tab1); 


      // check if there is a saved state to select active tab 
      if(savedInstanceState != null){ 
       getSupportActionBar().setSelectedNavigationItem(
          savedInstanceState.getInt(ACTIVE_TAB)); 
      } 


      new CollectMaterials(context,resources).execute(); 

     } 





//This is the BooksFragment Listener that would make the Tab components to listener to a tab click events 
    public class BooksListener<T extends SherlockListFragment> implements ActionBar.TabListener{ 
     private BooksFragment mFragment; 
     private final Activity mActivity; 
     private final String mTag; 
     private final Class<T> mClass; 


     public BooksListener(Activity activity, String tag, Class<T> clz) { 
     mActivity = activity; 
     mTag = tag; 
     mClass = clz; 

     } 

     public void onTabSelected(Tab tab, FragmentTransaction ft) { 
     // Check if the fragment is already initialized 
      Bundle bundle = new Bundle(); 
      bundle.putString("CategoryID", categoryID); 

     if (mFragment == null){ 
      // If not, instantiate and add it to the activity 
      mFragment = (BooksFragment) Fragment.instantiate(
          mActivity, mClass.getName()); 
      mFragment.setArguments(bundle); 

     // mFragment..setProviderId(mTag); // id for event provider 
      ft.add(android.R.id.content, mFragment, mTag); 
     } else { 
      // If it exists, simply attach it in order to show it 
      mFragment.setArguments(bundle); 
      ft.attach(mFragment); 
     } 

     } 

     public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
     if (mFragment != null){ 
      // Detach the fragment, because another one is being attached 
      ft.detach(mFragment); 
     } 
     } 

     public void onTabReselected(Tab tab, FragmentTransaction ft) { 
     // User selected the already selected tab. Usually do nothing. 

     } 
    } 




//This is my fragment code below. I would to get the CategoryID here 


public class BooksFragment extends SherlockListFragment{ 

    TextView textview = null; 

    @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.books, container, false); 
     // do your view initialization heres 
     textview = (TextView)view.findViewById(R.id.textView1); 

     Bundle bundle =this.getArguments(); 

     if(bundle != null){ 
      String id = bundle.getString("CategoryID"); 
      Log.i("CategoryID",id); 

      textview.setText(id); 
     } 
     return view; 
     } 

} 

Answer 1

Vous pouvez faire quelque chose comme ceci:

YourFragment yourFrag = new YourFragment(); 
    Bundle bundle = new Bundle(); 
    bundle.putString("CATEGORY_ID", CategoryID); 
    yourFrag.setArguments(bundle); 

pour récupérer les informations faire dans votre fragment:

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

    View view = inflater.inflate(R.layout.books, container, false);  

    Bundle bundle = getArguments(); 
    if(bundle != null){ 
    String CategoryID = bundle.getString("CATEGORY_ID", "no argument pass"); 
    } 

Answer 2

Il est possible de passer un Bundle à un Fragment par l'obtention d'une référence de la Fragment et en utilisant son setArguments(); vous passez le Bundle à setArguments(). Ensuite, à l'intérieur du Fragment, utilisez pour récupérer le Bundle.
