Ich habe keine Ahnung, wie die Frage der android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0. habe ich versucht zu lösen, bei dem Update den folgenden Code hinzugefügt() in der MessageStore.java:
if (cursor!= null && cursor.moveToFirst())
aber noch nichts. Kann mir jemand helfen? Die Anwendung stürzt jedes Mal ab, wenn ich sie lade.
Vielen Dank im Voraus.
Niemals ein Bild mit Code hochladen, einfach hier kopieren und einfügen und "die Code-Option" verwenden – Aspicas
Es scheint, dass der Cursor nicht richtig ausgefüllt wird. Sind Sie sicher, dass Einträge in der Tabelle vorhanden sind, in der Sie die Abfrage ausführen? –
