ListView öffnet Aktivität wenn das Element geklickt wird?

Im Versuch, Bauten diese app, die einfach aus einer ListView und verschiedene andere Aktivitäten, die aufgerufen wird, wenn ein Element aus der Ansicht geklickt wird. Jedoch, ich bin nicht in der Lage einen funktionierenden onclicklistener in der Haupt-Aktivität. Mit dem code unten, ich bin nicht in der Lage, um die Aktivität öffnen.

Hier ist der code:

public void setOnItemClickListener(AdapterView<?> parent, View view,
      int position, long id) {
    switch( position )
    {
       case 0:  Intent newActivity0 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity0);
                break;
       case 1:  Intent newActivity1 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity1);
                break;
       case 2:  Intent newActivity2 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity2);
                break;
       case 3:  Intent newActivity3 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity3);
                break;
       case 4:  Intent newActivity4 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity4);
                break;
    }
}

Jede Hilfe wäre sehr geschätzt 🙂 Kommentar, wenn U brauchen, um zu sehen, der vollständige code, ich update den post. Danke!

Dank für alle Antworten!
Hier ist der vollständige code:

Wenn es gibt keine bessere Methode, das zu erreichen, was meine app sollte, bitte posten! Im in der hoffnungslosen Notwendigkeit zu beenden, diese für einmal!!!!
