public void onClick(View v) {
  // TODO Auto-generated method stub

  Integer i,j,k;
switch(v.getId()){
case R.id.btn1:
  i = Integer.parseInt( "" + et1.getText());
  i-=1;
  et1.setText(i);
case R.id.btn2:
  i = Integer.parseInt( "" + et1.getText());
  i+=1;
  et1.setText(i);
case R.id.btn3:
  j = Integer.parseInt( "" + et2.getText());
  j-=1;
  et2.setText(j);
case R.id.btn4:
  j = Integer.parseInt( "" + et2.getText());
  j+=1;
  et2.setText(j);
case R.id.btn5:
  k = Integer.parseInt( "" + et3.getText());
  k-=1;
  et1.setText(k);
case R.id.btn6:
  k = Integer.parseInt( "" + et3.getText());
  k+=1;
  et1.setText(k);

}
}
};

이렇게 했는데 +버튼이나 -버튼을 누르면

갑자기 종료 되네요 이유가 뭘까요..

i,j,k가 정수형이어서 그런거 아닌가요? setText이 문자열을 매개변수로 받으니 스트링형으로 형변환해서 넣으면 될듯한데요.. 아닌가?? ;;;

스트링형으로 하면 +1 -1이 안되지 않을까요 ? 그래서 정수형으로 바꾼건데

2010.10.04 02:00:02

int 타입의 i라고 하는 변수는 말 그대로 정수형태로 값을 저장해야 하는데...
i = Integer.parseInt( "" + et1.getText());
빨간 글씨 부분이 정수로 받아들여지지 않을것같네요.

i = Integer.parseInt(et1.getText().toString());
으로 바꿔보세요..
