Android Countdown -Timer in der Quizanwendung ⇐ Java

[Guest]

Ich habe eine Quizanwendung gestellt, die 5 Fragen enthält. Ich habe eine Ergebnis -Aktivitäts -Seite erstellt, auf der das Ergebnis des Quizs angezeigt wird.
Ich habe für jede Frage einen Countdown -Timer von 20 Sekunden hinzugefügt. Wenn der Countdown -Timer fertig ist, wird er automatisch zur nächsten Frage bewegt. Wenn die Fragen beendet sind, sollte sie zur Seite der Ergebnisaktivität übergehen, um das Ergebnis anzuzeigen. Wenn ich keine Antwort auswähle und der Timer beendet ist, wechselt der Applicaton nicht zu meiner Ergebnis der Ergebnisaktivität. Der Timer beginnt immer wieder auf derselben Frage, bis ich eine Option auswähle < /p>

Hier ist mein Code: < /p>
