mein xml-Code erhalten
aber ich versuche diesen Code, nur das erste Bild anzeigen, ein anderes erschien nicht hilf mir !!
nur ein Datenblatt (eine Zeile) erhalten ist erfolgreich. ich weiß nicht, wie man Gesamtreihendaten erhält .... bitte helfen Sie mir. retten mein Leben bitte
Weil Sie nur eine image_url in imageUrlList hinzufügen. –
Sie fügen nur 'image_url' zur Liste hinzu – Dhina
Wenn Sie alle image_url in listview hinzufügen möchten, müssen Sie dies tun. imageUrlList.add (image_url); imageUrlList.add (image_url1); imageUrlList.add (image_url2); imageUrlList.add (image_url3); –
