Ich möchte eine automatically play next song Option hinzufügen, wenn der vorherige in meiner Android App abgeschlossen ist. Ich habe viele Wege versucht, aber gescheitert. Bitte geben Sie vollen Code, keine Hinweise. Hier sind die Voll Klasse:Wie kann ich die Option "Nächsten Song automatisch abspielen" in meiner Android App hinzufügen?

ich auf meinem apps Modifikation versuchen. Als erstes übergebe ich eine Methode und reiche die Klasse ein. Eine Person versucht mir zu helfen, aber ich bin nicht erfolgreich, es funktioniert nicht richtig. Letztes Mal habe ich meinen Code aber seinen Player immer wieder neu aufgelegt. Bitte beachten Sie meinen Code und geben Sie mir den besten Vorschlag. Ich bin kein professioneller Experte Entwickler. Ich bin ein Anfänger in der App-Entwicklung .. Also bitte gib mir den genauen Code.
, was in der ist 'Liede' Liste? Bitte geben Sie auch Ihren startPlaying() Methodencode an – Droidman
Songs ist 'private List songs = new ArrayList ();' –
Ich habe startPlaying Methode hinzugefügt. Plase, hilf mir. Wenn Sie noch etwas brauchen, bitte Informieren Sie mich @Droidman –
