JSON에 비동기 작업 추가하기 충돌 작업

Question

다음 코드에 AsyncTask (성공적으로)를 추가하는 방법을 알고 싶습니다. 나는 AsyncTask를 구현했다. (나의 지식에서 - 인터넷에서 찾은 정보를 사용하여) 그러나 충돌이 계속되고, 왜 확실한지 모르겠다. 어떤 도움을 주시면 감사하겠습니다!

Answer 1

죄송합니다. 자바 구문과 스레딩에 대한 기본적인 오해가 있습니다. 누군가가 코드를 "작동"하도록 다시 포맷 할 수도 있지만, 나는 책을 치지 않고 오랫동안 Painville에 머물러있을 것이라고 생각합니다.

실제로 "doInBackground"메소드에 코드가 없습니다. 또한 인수가 유효하지 않습니다. 계속 진행 하겠지만, 진지하게, Android 코드를 시도하기 전에 기본 Java 코딩 기술이 필요합니다. 다른 플랫폼과 동일합니다 (기본 코딩 기술이 필요합니다).

Answer 2

을 onCreate() 중에서 선택하십시오.
