안드로이드 개발 질문/답변
(글 수 45,052)
안녕하세요 ~! 저는 지금 listview를 만들고 잇는데요
현재 서버에 요청을 해서 서버의 DB에서 내용을 빼와서 listview에 뿌려주는 부분을 구현중에 있습니다.
현재 액티비티의 구성은 대략 이렇습니다
ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ
ㅣ 리스트뷰 ㅣ
ㅣ ㅣ
ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ
ㅣEditText ㅣ Buttonㅣ
ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ
대략 이런식으로 구성되어 있는데,
이 액티비티에 들어오면 바로 리스트뷰의 내용이 들어오질 않습니다.
EditText를 한번 눌러야 그제서야 내용이 나옵니다..
제가 예상하는 문제로는 thread에서 listview에 들어올 데이터를 가져올때 문제가 발생되는것같아
여기저기 다 쑤셔보고 runOnUiThread도 건드려보기도 했지만 전혀 모르겠습니다
이런 지식이 너무 절실한지라 여쭙겠습니다 ㅠ.ㅠ...
소스는 다음과 같습니다

코드하이라트 기능좀 써주시길.. 본인이봐도 이해 못하실 소스이실텐데
