Hello, I'm trying to create an option in my application, that when I click the photo I'll be redirected to another screen, with the photo selected in a imageview and a texview to comment!
What is the biggest problem I'm doing with a adapter , that is, I have the photos posted and I use a dialog alert to go to another activity ! I can not turn it into a array , I'm simply passing your URL to another screen as String , but I can not retrieve it, and move to Image view , could someone help me:
follow my code:
My adapter , first activity:
