我使用custom listivewwith has buttonGroupcontaing 5 radiobuttonsin each row ,

   setOnCheckedChangeListener(new OnCheckedChangeListener() {
   @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
    int selectedId =viewHolder.radioGroup1.getCheckedRadioButtonId();
    }
    }

这个方法 selectedId 总是返回相同的值，所以我无法知道选择了哪个单选按钮，请帮助，以下是我的代码，

custom listview在您的点击项侦听器 中使用以下代码

RadioButton radio = (RadioButton) arg1.findViewById(your id);
