Android: Comment faire un ListView cliquable avec un ContextMenu?

J'ai un ListView cliquable et essaye de faire un menu de contexte pour les articles mais si j'obtiens un clic long la première fois il active la méthode onListItemClick à la place. La prochaine fois que cela fonctionne. Si j'active le menu contextuel avec openContextMenu, il lance un StackOverflowError.Android: Comment faire un ListView cliquable avec un ContextMenu?

J'ai résolu mon problème! Voir à la fin de ce post.

Mon activité:

@Override 
public void onCreate(Bundle icicle) { 

    super.onCreate(icicle); 
    setContentView(R.layout.search); 

    getWords(getIntent());  
} 

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
     super.onListItemClick(l, v, position, id); 
     String lemma = (item.get(position)); 

     Intent intent = new Intent(this, EntryActivity.class) 
      .putExtra(CL.DOC, doc) 
      .putExtra(CL.ENTRY, lemma); 
    startActivity(intent); 
} 

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
    menu.setHeaderTitle("Eintrag"); 
    getMenuInflater().inflate(R.menu.context, menu); 
} 

public boolean onContextItemSelected(MenuItem item) { 
    //TODO: switch 
    return super.onContextItemSelected(item); 
} 

private void getWords(Intent intent) { 
    doc = (CLDocument)intent.getSerializableExtra(CL.DOC); 
    item = doc.getEntries(); 

    ArrayAdapter<String> fileList = 
     new ArrayAdapter<String>(this, R.layout.row, item); 
    setListAdapter(fileList); 

    getListView().setOnItemLongClickListener(new OnItemLongClickListener() {  
     @Override 
     public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { 
      registerForContextMenu(view); 
      //openContextMenu(view);   
      return false; 
     } 
    }); 
}

Ma mise en page (search.xml):

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <EditText 
     android:id="@+id/edit_search" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:imeOptions="actionSearch" 
     android:inputType="text" 
     android:singleLine="true" /> 

    <ListView 
     android:id="@android:id/list" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     /> 

    <TextView 
     android:id="@android:id/empty" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="@string/nowords" 
     /> 

</LinearLayout>

J'ai changé le méthodes getWords et onCreateContextMenu et maintenant ça marche:

private void getWords(Intent intent) { 
    doc = (CLDocument)intent.getSerializableExtra(CL.DOC); 
    item = doc.getEntries(); 

    ArrayAdapter<String> fileList = 
      new ArrayAdapter<String>(this, R.layout.row, item); 
    setListAdapter(fileList); 

    registerForContextMenu(getListView()); 

//  getListView().setOnItemLongClickListener(new OnItemLongClickListener() {  
//   @Override 
//   public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { 
//    registerForContextMenu(view); 
//      
//    return false; 
//   } 
//  }); 


} 

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
    AdapterView.AdapterContextMenuInfo info = 
      (AdapterView.AdapterContextMenuInfo)menuInfo; 
    menu.setHeaderTitle(item.get(info.position)); 
    getMenuInflater().inflate(R.menu.context, menu); 

}

Merci à tous ceux qui ont essayé de m'aider!

qu'est ce que c'est ??? et publiez votre logcat s'il vous plaît – Elior

Par articles, je voulais dire les éléments de la liste. – Heinrich

Vous devez appeler registerForContextMenu avec votre ListView en tant que paramètre dans le rappel onCreate() de l'activité.

Ici: getListView().setOnItemLongClickListener(...) après un long clic, vous vous enregistrez pour le menu contextuel (registerForContextMenu(view)), donc il ne fonctionnera que la prochaine fois. Cependant, si vous voulez que le menu contextuel fonctionne depuis le début, vous devriez l'appeler plus tôt, par exemple avant la méthode registerForContextMenu(getListView()).
