保存JsonReuest数据的方向变化

Question

我正在Android中构建一个测试应用程序，问题是当我改变屏幕的方向时，片段再次被加载并且数据消失了，这是从Json请求的。

这是请求代码

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    String testDetailUrl = "http://www.json-generator.com/api/json /get/cqZnauiJbC?indent=2";
    ((TrikshaApplication) parentActivity.getApplication()).setTestTime(0);
    TaskResponseListener taskResponseListener = new TaskResponseListener();
    JsonRequest messageRequest = new JsonRequest(testDetailUrl, testQuestions[].class,
            taskResponseListener, taskResponseListener);
    uiHandler = new Handler();
    arrayList = new ArrayList<String>();
    if (!((TrikshaApplication) parentActivity.getApplication()).getCallingFragment().equals("Shiksha")) {
        timeLimitLauncher = new TimeLimitLauncher();
    }

    this.getServiceLocator().getRequestQueue(getActivity()).add(messageRequest);

}

以下是配置更改代码

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    LayoutInflater inflater = LayoutInflater.from(getActivity());
    populateViewForOrientation(inflater, (ViewGroup) getView());
    getActivity().setContentView(R.layout.fragment_test_question_ans_layout);
}

private void populateViewForOrientation(LayoutInflater inflater, ViewGroup viewGroup) {
     viewGroup.removeAllViewsInLayout();
     View subview = inflater.inflate(R.layout.fragment_test_question_ans_layout, viewGroup);

}

以下是我在活动清单文件中所做的更改

机器人：configChanges = “取向|屏幕尺寸| keyboardHidden”

我在layout-land文件夹中制作了两个布局，一个用于纵向，一个用于横向。
