这是我的适配器类,请查看它.

// VIewHolder
private class ViewHolder { TextView mTextView; RadioGroup mGroup; RadioButton mRedButton1,mRedButton2,mRedButton3; }
// bean类
public class MyQuestion { private String mQuestion; privatE int question_answed; public MyQuestion() { super(); } public String getmQuestion() { return mQuestion; } public void setmQuestion(String mQuestion) { this.mQuestion = mQuestion; } public int getQuestion_answed() { return question_answed; } public void setQuestion_answed(int question_answed) { this.question_answed = question_answed; }
}
这是我正在使用的ArrayList
private ArrayList<MyQuestion> mQuestionsList = new ArrayList<MyQuestion>();
