글고에서 텍스트를 확인하고 체크 박스 상태는 HTTP POST와 URL에이를 보내

Question

나는 1 버튼을 가지고

1 글고, 6 확인란과 (다른 활동) 1 텍스트 뷰

확인하면 는 첫째 온 클릭 버튼, 글고에서 텍스트를 가져 변수에 저장하고 확인란가 쳤다되었는지 확인 여부, 재향 군인 생성 : 나는이 원하는 리바일 및 setText to TRUE else FALSE.

둘째 HTTP POST 방법을 통해 URL에 확인란 및 글고의 7 개 변수를 보낼 수 있습니다. 그 후 서버 응답을 받고 그것을 보여주십시오 다른 활동으로 TextView

이것은 내 JAVA 파일이지만 작동하지 않습니다. 누구든지이 코드를 수정할 수 있습니까? 46 : 19130-19130 29.451/com.royalrandhawa.xemp E/AndroidRuntime : FATAL EXCEPTION : 메인 공정 :

당신이에 gettext에 오류가있다();

이 시도 :
