Answer 1

startActivityForResult(i,0);

이 부분에서 인텐트 뒤의 인자는 requestCode 입니다.

onActivityResult에서 분기 처리할때 requestCode 를 0으로 바꿔보세요.

 

Comments

혹시      intent.putExtra("image",singer.get(position).getimgid());
     intent.putExtra("name",singer.get(position).imgid);부분이 맞는건지 알수있을까요

앞은 수정을했는데 뒤에서 사진을 못넘기는것같네요..
