학점계산기를 만들면서 체크박스가 체크되있으면 스피너를 활성시키고 비활성 상태라면 스피너를 비활성 시키기 위해
체크박스에 setOnCheckedChangeListener 를 추가해주고 밑에서 제가 만든 리스너를 불러왔는데
뭐가 문제인지 체크박스를 클릭하면 앱이 자꾸 꺼지네요;
저번에 인터넷에서 프래그먼트는 메소드를 추상메소드만 만들고 엑티비티에서 정의해야한다고 본거 같은데
프레그먼트에서는 메소드를 쓰면 안되는 건가요?
답변 부탁드립니다. 그리고 혹시 코드중에 이상한 점이 있으면 알려주세요 ㅠㅠ
- 추가 -
따로 클래스를 만들어서 안하고
무기명 이너클래스로 만드니까 동작하네요?
chk1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
if (buttonView.getId() == chk1.getId()) {
if (isChecked) {
g_Sp1.setClickable(true);
s_Sp1.setClickable(true);
}
else {
g_Sp1.setClickable(false);
s_Sp1.setClickable(false);
}
}
}
});
어쩌란건지 ㅠㅠ
