如何使用现有的sqlite进行测验应用程序？

Question

我已经用dbhelper java类中的手动输入制作了一个测验应用程序。因为我想添加更多问题，所以我认为使用已经存在的现有SQLite数据库会更容易。我应该在dbhelper类中进行哪些更改？

.....
private  void fillQuestionTable(){
    soal q1 = new soal("A is correct", "A", "B","C", 1);
    addSoal(q1);
    soal q2 = new soal("B is correct", "A", "B","C", 2);
    addSoal(q2);
    soal q3 = new soal("C is correct", "A", "B","C", 3);
    addSoal(q3);
}

private void addSoal(soal soal){
    ContentValues cv = new ContentValues();
    cv.put(KuisEntry.KEY_QUES, soal.getQuestion());
    cv.put(KuisEntry.KEY_OPTA, soal.getOpta());
    cv.put(KuisEntry.KEY_OPTB, soal.getOptb());
    cv.put(KuisEntry.KEY_OPTC, soal.getOptc());
    cv.put(KuisEntry.KEY_ANSWER, soal.getAnswer());
    db.insert(KuisEntry.TABLE_QUEST, null, cv);
}

public List<soal> getAllQuestion(){
    List<soal> questionList = new ArrayList<>();
    db = getReadableDatabase();
    Cursor c = db.rawQuery(" SELECT * FROM " + KuisEntry.TABLE_QUEST, null);
    if(c.moveToFirst()){
        do{
            soal soal = new soal();
            soal.setQuestion(c.getString(c.getColumnIndex(KuisEntry.KEY_QUES)));
            soal.setOpta(c.getString(c.getColumnIndex(KuisEntry.KEY_OPTA)));
            soal.setOptb(c.getString(c.getColumnIndex(KuisEntry.KEY_OPTB)));
            soal.setOptc(c.getString(c.getColumnIndex(KuisEntry.KEY_OPTC)));
            soal.setAnswer(c.getInt(c.getColumnIndex(KuisEntry.KEY_ANSWER)));
            questionList.add(soal);
        }while(c.moveToNext());
    }
 c.close();
    return questionList;
}
