Wie Bild hinzufügen, um die navigation Schublade/ listeview?

Neues zu Android, ich habe eine navigation Schublade, die perfekt funktioniert. Aber jetzt will ich das Bild einfügen, die für jeden der option - wie 1 Bild für "home" und eine für "barcode Scannen" usw.

Habe ich einige Tutorials suchen, aber nicht die passende Lösung zu finden. Irgendwelche Vorschläge? vielen Dank im Voraus.

  • Oh! aber warum Sie mit der benutzerdefinierten navigation Schublade
  • Ich habe den code von irgendwo, so dass ich meine app auf die Spitze.
  • stackoverflow.com/a/29172779/1979882
  • wenn Sie mit Android studio 1.5.1 und höher, studio selbst gibt Klassen und die entsprechenden xml-zeichnen-navigation Schublade an den Start-von der Projekt-Erstellung.
  • Ich bin mit Android studio 1.4
  • Sie müssen eine benutzerdefinierte adapter statt ArrayAdapter.
  • androidhive.info/2013/11/...
  • Siehe meine Antwort, wenn Sie es finden helfen voll!
  • Vielen Dank allen für Ihre Antworten. Ich bin Art von kurze Zeit und war in der Hoffnung etwas zu finden, das Schnellste zu implementieren. Ich werde in dieser nach einer Weile.
