hinzufügen Bildansicht dynamisch anzeigen

dass ich android-Spiele, die über das view-Klasse.ich bin nicht mit layout.alle meine Bilder ist das zeichnen mit canvas.Nun mein problem ist ich kann nicht geben Sie eine bitmap

touchable Fall, wie Sie wissen.ich bin versucht, hinzuzufügen Bildansicht dynamisch zu meiner view-Klasse zu

verwenden berührbare Veranstaltung.warum ich versuche, um Bildansicht dynamisch?Weil ich bin nicht mit

layout.aber ich konnte nicht.gibt es irgendwelche Körper zu helfen?

here is my code:
