在Android中迭代ArrayList

Question

以下是我的代码 -

public class GameActivity extends Activity implements OnClickListener {
ImageView mainImage;
Button questionValue;
Button option1;
Button option2;
Button option3;
int rightAnswer;
Question question;
Intent intent;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);

    mainImage = (ImageView) findViewById(R.id.idc_questionImage);
    questionValue = (Button) findViewById(R.id.idc_question);
    option1 = (Button) findViewById(R.id.idc_questionOption1);
    option2 = (Button) findViewById(R.id.idc_questionOption2);
    option3 = (Button) findViewById(R.id.idc_questionOption3);


    Intent intent = getIntent();
    ArrayList<Question> questions = intent.getParcelableArrayListExtra("Question");

    for (Iterator iterator = questions.iterator(); iterator.hasNext();) {
         question = (Question) iterator.next();
        System.out.println("ArrayList " + question);

        mainImage.setBackgroundResource(question.getQuestionImage());
        questionValue.setBackgroundResource(question.getQuestionTitle());
        option1.setBackgroundResource(question.getOptionImage1());
        option2.setBackgroundResource(question.getOptionImage2());
        option3.setBackgroundResource(question.getOptionImage3());
        rightAnswer = question.getRightAnswerImage();

        if(question.getOptionImage1() == rightAnswer)
        {
            option1.setOnClickListener(this);
        }

        if(question.getOptionImage2() == rightAnswer)
        {
            option2.setOnClickListener(this);
        }

        if(question.getOptionImage3() == rightAnswer)
        {
            option3.setOnClickListener(this);
        }


    }

}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int position = v.getId();
    switch (position) {
    case R.id.idc_questionOption1:


            Intent intent = new Intent(this, GameActivity.class);
            startActivity(intent);
            Toast.makeText(this, "Option1", Toast.LENGTH_LONG).show();

        break;

    case R.id.idc_questionOption2:

             intent = new Intent(this, GameActivity.class);
            startActivity(intent);
            Toast.makeText(this, "Option2", Toast.LENGTH_LONG).show();

        break;

    case R.id.idc_questionOption3:

             intent = new Intent(this, GameActivity.class);
            startActivity(intent);
            Toast.makeText(this, "Option3", Toast.LENGTH_LONG).show();



        break;


    default:
        break;
    }

}

这里我的ArrayList包含两个Question类对象，我希望在Iterator循环启动时，然后加载我的视图进行第一次索引，然后选择我的一个选项，然后运行ArrayList的第二个索引。

但是在上面的场景中，完成循环执行了两次，然后加载了视图，并显示了最后一个索引的值。

我如何实现这一任务。请帮助我。

感谢任何帮助。提前致谢。
