1. Das Bluetooth auf der Ladedetailseite hat sich erfolgreich verbunden und den Status erhalten. Sie müssen zu den Plug-and-Charge-Seiteneinstellungen springen. Es besteht das Problem, dass die Einstellung nicht rechtzeitig nach erfolgreicher Einstellung aktualisiert wird. 2. Lösungen : A. Klicken Sie auf Plug-and-Charge, um
Plug -
and-Charge auszuführen. Schalten Sie beim Anzeigen der Seite zunächst alle Monitore auf dieser Seite aus.
B. Wenn Sie auf der Plug-and-Charge-Seite auf die Einstellungen klicken, wird der Befehl geschrieben und dann der Monitor eingeschaltet on. Nachdem Sie den entsprechenden Rückgabewert erhalten haben, kehren Sie zur Detailseite zurück und entladen Sie ihn in die Lebenszyklusfunktionen onHide und onUnload. Abhörcode
: Springen Sie zur Plug-and-Play-Seite
