Ich arbeite mit einem Projekt, um Bilder in einer Listenansicht anzuzeigen, und wenn wir auf ein Bild in der Listenansicht klicken, gehen Sie zur nächsten Absicht. Während ich klicke, wird die ID eines bestimmten Elements nicht an eine andere Absicht übergeben. Ich weiß nicht, was ich machen soll.Wie erhalte ich die ID eines Artikels in der Listenansicht, wenn wir auf den Artikel klicken?

Ich kann nicht sehen, was das mit MySQL – Strawberry
Wt über image_title und image_url zu tun hat. Gehen diese Werte in Secondpage.class? – Minkoo
nein, image_title und image url geht auch nicht – Jincy
