Wie benutzerdefinierte Ansichten auf meinem Bildschirm hinzufügen?
danke für Ihre Antwort.Es ist wirklich hilfreich und funktioniert gut hier. Aber die Sache ist, warum wir MessageBox beim ersten Laden der Anwendung hinzufügen müssen? Warum wir nicht auf Knopfdruck klicken, statt ein- und auszublenden. Ist es besser, wenn in meiner Anwendung mehr als 25-50 Ansichten vorhanden sind? – Tirth
MessageBox wird tatsächlich nur hinzugefügt, wenn Sie auf die Schaltfläche klicken. Es ist nur so, wie es gemacht wird, um zu reagieren. Wie Sie vielleicht wissen, handelt es sich bei der reagierenden Anwendung um eine Hierarchie von Komponenten, und bei jeder Zustandsänderung wird die gesamte Hierarchie aktualisiert. Jede Komponente hat eine Renderfunktion und in der Renderfunktion wählen wir aus, was für diese Komponente basierend auf dem Status gerendert werden soll. In diesem Fall wird der Status von der Schaltfläche beeinflusst. Ich würde vorschlagen, dass Sie Videos über das Arbeiten von reagieren schauen. Ich hoffe es hilft. Lass es mich wissen, wenn es noch nicht klar ist. –
@agend_hunt Kumpel vielen Dank :) – Tirth
