Ich habe eine eigene Implementierung der Marquee-Klasse, da der Benutzer das Laufschrift Verhalten (kein Bildlauf, Bildlauf, Bildlauf) für den Text in meiner Musik-App entscheiden kann. Das Problem tritt auf, wenn der Benutzer beginnt, die Songs abzuspielen, da er im Layout ständig timer text (id: tv_playtime) aktualisiert.benutzerdefinierte Klasse Laufschrift Text neu gestartet, während eine andere Textansicht in einem komplexen Layout ändern

Ich mag hier das Scroll-Verhalten von marqueetext1 steuern, was in Ordnung arbeitet, wenn der Song angehalten wird (Da Timer Textfeld wird nicht aktualisiert).
Ich habe ähnliche Probleme versucht, aber keiner von ihnen für mich
TextView restarts Marquee when changing another TextView in same LinearLayout
Setting of TextView stops marquee scrolling of other TextView
Android, RelativeLayout restarts Marquee-TextView when changing ImageView in same RelativeLayout
Hinweis arbeiten: Bin gestu mit res für Media-Player-Steuerung (Next, Previous, Play, Pause)
Meine Annahme ist, dass es wegen des Layouts geschieht, da ich ein Debugging in benutzerdefinierten Marquee-Klasse durchgeführt habe, deren Eigenschaften den Marquee-Neustart hier nicht beeinflussen. Ich habe OnFocusChanged, OnWindowFocusChanged und IsFocused-Methoden in meiner abgeleiteten Marquee-Klasse überschreiben, um die Textansicht alle fokussiert zu machen. Was fehlt hier?
