Exception ClassNotFound lors du gonflage Afficher dans une zone AlertBox

Question

J'essaye de gonfler un XML (Layout) à l'intérieur d'un AlertBox.

Voici le XML que je veux gonfler ...

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

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/update_information" /> 

    <CheckBox 
     android:id="@+id/chbDisplay" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Don't Show Again" 
     android:checked="true" /> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 

     <Button 
      android:id="@+id/btnCancel" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Cancel" /> 

     <Button 
      android:id="@+id/btnOk" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Ok" /> 



    </LinearLayout> 

</LinearLayout> 

C'est le code que je utilise pour gonfler le XML ...

private void display_Update_Info() { 
     // TODO Auto-generated method stub 

     LayoutInflater in = new LayoutInflater(this) { 

      @Override 
      public LayoutInflater cloneInContext(Context newContext) { 
       // TODO Auto-generated method stub 
       return null; 
      }//This code is auto generated. I have no idea what is this... 
     }; 

     final View update = in.inflate(R.layout.updateinformation, null); 


     AlertDialog.Builder updateInfo = new Builder(this); 
     updateInfo.setView(update); 
     updateInfo.show(); 

    } 

Voici la trace Logcat. ..

aussi, si quelqu'un peut me dire, quelle est l'utilisation du code généré automatiquement ...

@Override 
public LayoutInflater cloneInContext(Context newContext) { 
// TODO Auto-generated method stub 
return null; 
} 

Je reçois près de force quand je suis en train d'exécuter l'application ...

Answer 1

au lieu de cette

LayoutInflater in = new LayoutInflater(this) { 

     @Override 
     public LayoutInflater cloneInContext(Context newContext) { 
      // TODO Auto-generated method stub 
      return null; 
     }//This code is auto generated. I have no idea what is this... 
    }; 

utilisent ce

LayoutInflater in = getLayoutInflater(); 

et pour la deuxième partie voir les docs API http://developer.android.com/reference/android/view/LayoutInflater.html#cloneInContext(android.content.Context).
