Verwenden von AlertDialog.Builder zum Erstellen von benutzerdefinierten AlertDialog Klasse

Question

Ich habe eine Klasse FoodDialog, die AlertDialog erweitert, die ich angepasst habe, wie ich es aussehen möchte.

ich jetzt will die positiven/negativen Tasten mit einem AlertDialog.Builder jedoch bearbeiten, wenn ich eine Instanz von FoodDialog mit einem Baumeister zu bauen versuchen, ich bin vor ein ‚Inkompatible Typen‘ Fehler, wenn der Builder für AlertDialog bittet Stattdessen gebe ich es mit einer Erweiterung von AlertDialog - gibt es einen Weg um dies?

Wenn nicht, gibt es eine Möglichkeit, die positiven/negativen Tasten meiner benutzerdefinierten AlertDialog Klasse FoodDialog zu bearbeiten?

Unten ist meine FoodDialog Klasse. Die Ja/Nein-Tasten, die ich dort habe, sind diejenigen, die ich selbst erstellt habe, aber ich möchte, dass diejenigen, die Teil des AlertDialog.Builder sind stattdessen angezeigt werden, wie diese Tasten außer Sicht geraten, wenn die Soft-Tastatur erscheint:

public class FoodDialog extends AlertDialog implements OnClickListener {

Answer 1

Sie können Ihre Tasten fangen Zuhörer anklicken, wie folgt:

yesBtn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      //yes button click code here 
     } 
    }); 

noBtn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      //no button click code here 
     } 
    }); 

Sie die logcat verwenden können, um zu sehen, ob Ihre Zuhörer gefeuert werden.
