Answer 1

Nun, ich weiß nicht genau, aber so weit ich denke, versuchen, alle Linien zu ändern ähnlich wie:

vitaminA.setOnClickListener ((OnClickListener) this); zu so etwas

vitaminA.setOnClickListener (this); ,

und lassen Sie Ihre Aktivität OnClickListener implementieren und nicht implementierten Methoden hinzufügen, nur die Vorschläge folgen, die Sie zur Verfügung stellen eclipse ..

Versuchen Sie dies sein kann es Ihnen helfen kann .........

Answer 2

Ihr Problem wird in das Protokoll geschrieben

ClassCastEx nehmung

an diesem Ort

onCreate (VitaminTable.java:38)

so auf der Linie 38 deiner Sicht in den falschen Typ ohne

leid, aber können Sie nicht mehr helfen Gießen Ihre Layout-XML-Datei, aber überprüfen Sie den Typ der Ansicht, die Sie erstellt haben und das sollte den Trick tun

Answer 3

Sie haben den Paketnamen rückwärts. Es sollte "com.xyz.vitaminTable" oder wahrscheinlich besser "com.xyz.vitamin" sein. Aber das sollte kein Problem sein, wenn du es nicht anders im Manifest verwendest. Bitte geben Sie den Inhalt der AndroidManifest.xml an.

Um dies auf OnClickListener VitaminTable zu werfen, muss OnClickListener implementiert werden.

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