버튼 클릭리스너안에 for문 에러

                for(i=0;i<8;i++){
                    lab[i] = mText.getText().toString();

                mText.setText("00:00:00:00");
                handler.removeCallbacks(StopWatch);
            }
        });
    }
}

mBtn2 클릭리스너에서 막히는데요 ㅠㅠ

클릭 리스너안에 for문을 이용해 TextView 문자열가져오면 원래 에러가 나나요?

Answer 1

String lab [] =new String[7];

for(i=0;i<8;i++){

그리고 질문하실땐 Exception 로그도 같이 올리시는게 좋습니다.
