}

startActivityForResult(intent,EDIT_ACT);
}

String str = String.format("%s", data.getStringExtra("work"));
Log.v("test111","click!!"+str);
buttonNames[Position] = str;
timetable.setAdapter(buttonAdapter);
}
break;
}
}
}

위의 화면처럼 실행이 됩니다.

각 셀에 값을 넣고 종료를 하면 다시 실행 했을때 저장이 되지 않습니다.

어떻게 해야 할까요?

그리고 저 각 칸마다 경계선을 그려주고 싶은데 어떤 방법이 있을까요?

도와주시면 감사하겠습니다 ㅠㅠ
