Aktivieren Sie nur ein Kontrollkästchen der Kontrollkästchen für die Begrüßungseinstellungen
Ich habe App-Start abhängig von der Nutzerpräferenz mit drei verschiedenen Kontrollkästchen:
1 - App ohne Splash und Musik starten.
2- App nur mit Splash starten.
3-App mit Spalsh und Musik starten.
mit dem folgenden code funktioniert es einwandfrei.
Aber noch zwei Punkte zu erreichen:
ZUERST Es sollte nur ein Kontrollkästchen aktiviert sein.
ZWEITE Nachdem Sie eines der Kontrollkästchen aktiviert haben, kehren Sie zur Hauptaktivität zurück. Hier können Sie die App entweder mithilfe von beendenZurück-Button oderBeenden-Taste Was ich bereits in meinem Optionsmenü habe, ist das Problem, dass entweder mitZurück-Button oderBeenden-Taste es reagiert nicht auf den ersten Klick, ich muss zweimal klicken, um die App zu beenden.
aber ich kann es nicht erreichen,
Jede Hilfe wird gebeten.

Im xml Ordner:prefs.xml
<?xml version="1.0" encoding="utf-8" ?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference android:title="without splash screen"
android:defaultValue="true"
android:key="without_splash_screen"
android:summary="Start app without splash"/>
<CheckBoxPreference android:title="splash screen"
android:defaultValue="true"

<CheckBoxPreference android:title="splash screen music"

AKTUALISIEREN:
Ich habe auch den folgenden Code ausprobiert, aber er ändert nichts. Trotzdem können alle Kontrollkästchen überprüft werden:

Irgendwelche Ratschläge, danke.
UPDATE 3 (GANZES PROJEKT):
1- ein markiertes Kästchen perfekt erreicht.
2- entweder mit der Zurück-Taste oder der Beenden-Taste in MainActivity, reagiert nicht auf den ersten Klick, ich muss zwei- oder dreimal klicken, um die App zu beenden.
