up Ich habe eine schwebende Wirkung button.On Klick davon, präsentiere ich alle Videodateien zeige, in Benutzer-phone.When einer bestimmten Datei ausgewählt wird, um es zu firebase Speicher hochgeladen wird. aber ich möchte mit einem EdiText mit den Namen der Datei Benutzer choose.Then Benutzer eine Benachrichtigung Dialog zeigen, können Sie den Namen der Datei bearbeiten und auf Klick auf Schaltfläche ja die Datei-Upload sollte start.I zeige, meine alertdialog in schwebenden Aktionstaste. Ich kann Alarmdialog in AsyncTask nicht zeigen, da es Fehler gibt. So , was ich will, ist, eine AlertDialog anzeigen, wenn die Benutzer eine Datei auf Klick wählt Aktion button.The schwimmender EditText von AlertDialog sollte den Namen der Datei haben, die Benutzer auswählen, und Benutzer können sie bearbeiten, wenn er/sie will und auf Klick ja Schaltfläche nur die Datei sollte auf firebase Speicher hochgeladen werden.Alertdialog zeigen pflegt meine EditText
auszuführen, wie den Namen der Datei erhalten i wählen, in EditText die Warnmeldung? – Pritish
Sie erhalten diese Daten in der Methode onActivityResult, also verschieben Sie die Erstellung des Alarmdialogs dorthin –
