这是我的测试片段，我在其中基于开关构建列表：
public class TestFragment extends Fragment {
public String Workshop;
public int NumberOfQuestions;
public Button SaveButton;
public TextView GradeView;
public String Grades;
private OnFragmentInteractionListener mListener;
public TestFragment() {}
@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle bundle){
View rootView = inflater.inflate(R.layout.questionscomplete,
container, false);
Workshop = getArguments().getString("Workshoptitle");
GradeView = ((TextView) rootView.findViewById(R.id.GradeView));
// Inflate the layout for this fragment
if (!Workshop.equals("Doodlz Drawing")) {
rootView = inflater.inflate(R.layout.fragment_test,
container, false);
final ListView lv1 = (ListView) rootView.findViewById(R.id.listview);
ArrayList image_details = getListData();
lv1.setAdapter(new CustomListAdapter(getActivity(), image_details));
SaveButton = ((Button) rootView.findViewById(R.id.Save));
SaveButton.setOnClickListener(Grading);
}
return rootView;
}
private ArrayList getListData() {
ArrayList<QuestionItem> results = new ArrayList<QuestionItem>();
switch (Workshop) {
case "Android Studio":
Workshop = "Android Studio";
QuestionItem[] Item1 = new QuestionItem[3];
QItem WS1 = new QItem();
NumberOfQuestions = Item1.length;
String[] WS1Q = WS1.getQuestions(Workshop, NumberOfQuestions);
String[] WS1QA = WS1.getAnswers(Workshop);
for (int i = 0; i < NumberOfQuestions; i++) {
Item1[i] = new QuestionItem();
Item1[i].setQuestion(WS1Q[i]);
Item1[i].setAnswer1(WS1QA[i * 10 + 0]);
Item1[i].setAnswer2(WS1QA[i * 10 + 1]);
Item1[i].setAnswer3(WS1QA[i * 10 + 2]);
Item1[i].setAnswer4(WS1QA[i * 10 + 3]);
// Toast.makeText(getActivity(), Item1[i].GetAnswer(),
// Toast.LENGTH_LONG).show();
results.add(Item1[i]);
}
break;
case "Java Basics":
Workshop = "Java Basics";
QuestionItem[] Item2 = new QuestionItem[5];
QItem WS2 = new QItem();
NumberOfQuestions = Item2.length;
String[] WS2Q = WS2.getQuestions(Workshop, NumberOfQuestions);
String[] WS2QA = WS2.getAnswers(Workshop);
for (int i = 0; i < NumberOfQuestions; i++) {
Item2[i] = new QuestionItem();
Item2[i].setQuestion(WS2Q[i]);
Item2[i].setAnswer1(WS2QA[i * 10 + 0]);
Item2[i].setAnswer2(WS2QA[i * 10 + 1]);
Item2[i].setAnswer3(WS2QA[i * 10 + 2]);
Item2[i].setAnswer4(WS2QA[i * 10 + 3]);
results.add(Item2[i]);
// Toast.makeText(getActivity(), Item2[i].GetAnswer(),
// Toast.LENGTH_LONG).show();
}
break;我的列表适配器：
public class CustomListAdapter extends BaseAdapter {
private LayoutInflater layoutInflater;
public String Answer;
public String[] Answers;
private ArrayList<QuestionItem> listData;
public CustomListAdapter(Context aContext, ArrayList<QuestionItem> listData) {
this.listData = listData;
layoutInflater = LayoutInflater.from(aContext);
}
@Override
public int getCount() {
return listData.size();
}
@Override
public Object getItem(int position) {
return listData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
View v = convertView;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.questions, null);
holder = new ViewHolder(

holder.QuestionView = (TextView) convertView.findViewById(R.id.q);

holder.Answer3Button = (RadioButton) convertView.findViewById(R.id.qa3);
holder.Answer4Button = (RadioButton) convertView.findViewById(R.id.qa4);
holder.ButtonGroupView = (RadioGroup) convertView.findViewById(R.id.group);
convertView.setTag(holder);
holder.ButtonGroupView.getCheckedRadioButtonId();
holder.ButtonGroupView
.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup group,
int checkedId) {
Integer pos = (Integer) group.getTag(); // To identify the Model object i get from the RadioGroup with getTag()
// an integer representing the actual position
QuestionItem element = listData.get(pos);
switch (checkedId) { //set the Model to hold the answer the user picked
case R.id.qa1:
element.setAnswer("1");
"Log.d(listData.get(pos).toString(), element.GetAnswer());
break;

element.setAnswer("2");
"Log.d(listData.get(pos).toString(), element.GetAnswer());
break;
case R.id.qa3:
element.setAnswer("3");
"Log.d(listData.get(pos).toString(), element.GetAnswer());
break;
case R.id.qa4:
element.setAnswer("4");
"Log.d(listData.get(pos).toString(), element.GetAnswer());
break;
default:
element.setAnswer(null); // Something was wrong set to the default
}
}
});
} else {
holder = (ViewHolder) convertView.getTag();
}
QuestionItem element = (QuestionItem) getItem(position);
holder.QuestionView.setText(listData.get(position).getQuestion());
holder.Answer1View.setText(listData.get(position).Getanswer1());
holder.Answer2View.setText(listData.get(position).Getanswer2());
holder.Answer3View.setText(listData.get(position).Getanswer3());
holder.Answer4View.setText(listData.get(position).Getanswer4());
holder.ButtonGroupView.setTag(new Integer(position)); // I passed the current position as a tag
return convertView;
}
//
class ViewHolder {
TextView t = null;
TextView QuestionView;
TextView Answer1View;
TextView Answer2View;
TextView Answer3View;
TextView Answer4View;
RadioButton Answer1Button, Answer2Button, Answer3Button, Answer4Button;
RadioGroup ButtonGroupView;
}}我的问题项目：
public class QuestionItem {
private String Question;
private String Answer1;
private String Answer2;
private String Answer3;
private String Answer4;
private String Answer;
public String getQuestion() {
return Question;
}
public void setQuestion(String Question) {
this.Question = Question;
}
public String Getanswer1() {
return Answer1;
}
public void setAnswer1(String Answer1) {
this.Answer1 = Answer1;
}
public String Getanswer2() {
return Answer2;
}
public void setAnswer2(String Answer2) {
this.Answer2 = Answer2;
}
public String Getanswer3() {
return Answer3;
}
public void setAnswer3(String Answer3) {
this.Answer3 = Answer3;
}
public String Getanswer4() {
return Answer4;
}
public void setAnswer4(String Answer4) {
this.Answer4 = Answer4;
}
public String GetAnswer() {
return Answer;
}
public void setAnswer(String Answer) {
this.Answer = Answer;
}
}我想保存所有答案并将它们与正确答案进行比较，并将分数保存为另一个片段中的变量。
更新：添加“Log.d(listData.get(pos).toString(), element.GetAnswer());” 我可以看到它正在存储选择的答案，所以我如何在测试片段中请求它们并检查它们
我尝试了几件事，但找不到解决方案。请帮助:)？
