Android测验应用

Question

我正在制作一个测验应用程序，在执行此操作时，我的分数不会增加 即使答案是正确的。当我比较currentQ.getANSWER().equals(answer.getText())并且此时score ++之后，得分不会增加。以下是我的代码：

 butNext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RadioGroup grp=(RadioGroup)findViewById(R.id.radioGroup1);

           answer=(RadioButton)findViewById(grp.getCheckedRadioButtonId());

            if(currentQ.getANSWER().equals(answer.getText()))
            {
                score ++ ;

                Log.d("tag"," " +score);
            }



            if(qid < 5) {

                currentQ = quesList.get(qid);



            }

            setQuestionView();




        }
    });

在下一个按钮点击中，我想保存先前的响应并增加分数，但这不会发生。

DBhelper

 private void addQuestions()
{
    Question q1=new Question("Which company is the largest manufacturer" +
            " of network equipment?","HP", "IBM", "CISCO", "C");
    this.addQuestion(q1);
    Question q2=new Question("Which of the following is NOT " +
            "an operating system?", "SuSe", "BIOS", "DOS", "B");
    this.addQuestion(q2);
    Question q3=new Question("Which of the following is the fastest" +
            " writable memory?","RAM", "FLASH","Register","C");
    this.addQuestion(q3);
    Question q4=new Question("Which of the following device" +
            " regulates internet traffic?",    "Router", "Bridge", "Hub","A");
    this.addQuestion(q4);
    Question q5=new Question("Which of the following is NOT an" +
            " interpreted language?","Ruby","Python","BASIC","C");
    this.addQuestion(q5);
}

这是我的dbhelper，我在其中添加了所有问题和答案。 我该怎么办？欢迎提出任何建议。
