현재 퀴즈 앱을 만들고 있는데 점수를 추가하고 싶습니다. 아래 그림을 볼 수 있습니다. 각 플래그는 단편입니다.이 플래그를 누르면 오른쪽에서 대답을 제출할 수 있습니다. Android Studio 퀴즈 앱 저장 점수
올바른 대답을 입력
는 "올바른"메시지가 나타납니다, 당신은 다음 플래그로 이동할 수 있습니다. 나는 득점 1을주고, 옳은 대답은 건너 뛰거나 눌렀을 때, 0 점을주고 싶다. 결국 점수가 요약됩니다. 그러나, 나는 이것을 어떻게하는지 확신 할 수 없다. 점수가 등록 될 ScoreActivity.java 파일을 만들었지 만 (현재 비어 있음), 아래 코드를 작성하려고 시도했습니다.Play.java

.isChecked()를 빨간색으로 표시됩니다. 뭔가 가져올 필요가 있습니까?
1). 2)'editText.setTag (score)'를 사용하거나 답변을 확인하고 저장 함수에 부울을 전달하거나 활동에 점수 변수를 보관합니다. 3) 매번 동일한 SharedPreferences 키를 점수에 추가하는 대신 0 또는 1로 덮어 씁니다. – NineToeNerd
