Helper = new myDBHelper(this);
sqlDB = Helper.getReadableDatabase();
Cursor cursor;
cursor = sqlDB.rawQuery("SELECT * FROM readTBL;", null);
String[] result = new String[8];
for(int i=0; i<8; i++){
cursor.moveToNext();
result[i] = cursor.getString(0);
}
int j = 0;
for(int k=0; k<8; k++){
for(int i=0; i<4; i++){
if(result[k] == votedBook[i]){
cursor.moveToPosition(k);
et[j].setText(cursor.getString(0));
j++;
}
}
}
votedBook 배열의 데이터를 이용해서 같은 행의 다른 열을 출력하고 싶습니다ㅠㅠㅠ
votedBook에는 title 열의 자료가 들어 있는 상태입니다! 그래서 같은 cursor행의 author열을 출력하고 싶습니다ㅠㅠ
아래같은 에러가 뜹니다ㅠㅠ
제발 도와주세요ㅠㅠ
