Answer 1

Eh bien, je ne sais pas exactement, mais pour autant que je suppose, essayez de changer toutes les lignes similaires à:

vitaminA.setOnClickListener ((OnClickListener) this); à quelque chose comme ceci

vitaminA.setOnClickListener (this); ,

et laissez votre activité mettre en œuvre onCLickListener, et ajouter des méthodes inappliquées, il suffit de suivre les suggestions qui éclipsent vous fournir ..

Essayez cela peut être il peut vous aider .........

Answer 2

votre problème est écrit dans le journal

ClassCastEx ception

à cet endroit

onCreate (VitaminTable.java:38)

donc sur la ligne 38 de votre coulée votre point de vue dans le mauvais type

désolé mais ne peut pas vous aider plus sans votre mise en page fichier XML, mais vérifiez le type de vue que vous avez créé et qui devrait faire l'affaire

Answer 3

Vous avez le packagename en arrière. Il devrait être "com.xyz.vitaminTable" ou probablement mieux "com.xyz.vitamin". Mais cela ne devrait pas poser de problème si vous ne l'utilisez pas différemment dans le Manifeste. Veuillez fournir le contenu du fichier AndroidManifest.xml. Pour convertir ceci en OnClickListener, VitaminTable doit implémenter OnClickListener.

public class VitaminTable extends Activity implements OnClickListener { 
    ... 
    implement OnClickListener-Methods here 
    ... 
}
