Suche mit Android-Suche Ansicht Widget zeigt nicht die richtige Position nach der Suche

Question

Ich möchte eine Listenansicht in meiner Android-Anwendung zu suchen, so dass ich Android Widget Widget für diese Suche verwendet. Ich habe die Suche erfolgreich durchgeführt, aber das Problem tritt nach der Suche ein. Wenn ich es suche gibt mir gefilterte Ergebnisse, aber wenn ich auf die gefilterten Elemente klicke, gibt es mir falsche Position. Bitte helfen Sie mir dabei.

Answer 1

Das Problem ist, dass die Suche das Array Filterung innen der Adapter coverList. Also, in dem Adapter ist die Position des Artikels in Ordnung.

Aber dann rufen Sie die Aktion außerhalb des Adapters (in der Klasse) mList. An dieser Stelle suchen Sie im ursprünglichen Array, das keinen Filter hat. Also ist die Position falsch.

Sie müssen den Kontakt aus dem gefilterten Array im Adapter wiederherstellen. Also in Ihrem MainActivity:

mcontact.setOnItemClickListener(new AdapterView.OnItemClickListener() 
    { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
     { 
      number = mMyContactsAdapter.getItem(position).getNumber(); 
      email = mMyContactsAdapter.getItem(position).getEmail(); 
      view.setSelected(true); 
    } 
}); 

Answer 2

benötigen Sie den Adapter in mcontact Schaltfläche klicken aktualisieren

mMyContactsAdapter.getItem(position); 
Contacts mList = getSearchResults(sv.getQuery().toString()).get(position); 
number = mList.get(position).getNumber(); 
email = mList.get(position).getEmail();
