Question

我试图防止在旋转变化时丢失webview状态，这是我的片段代码：

public class ContentFragment extends Fragment {

    private String mArticleId, imageUrl;
    private WebView mContent;
    private ImageView mBackground;
    private LinearLayout mLayout;
    private Bundle webViewBundle;

    public static ContentFragment newInstance(String idcko) {
        ContentFragment f = new ContentFragment();
        Bundle args = new Bundle();
        args.putString("idcko", idcko);
        f.setArguments(args);
        return f;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setRetainInstance(true);
        mArticleId = getArguments().getString("idcko");

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View root = inflater.inflate(R.layout.fragment_content, null);
        mContent = (WebView) root.findViewById(R.id.content_web);
        if (webViewBundle == null) {
            new FetchContent().executeOnExecutor(
                    AsyncTask.THREAD_POOL_EXECUTOR, "");
        } else {
            Log.e("else", "");
            mContent.restoreState(webViewBundle);
        }
        return root;
    }

    @Override
    public void onPause() {
        super.onPause();
        webViewBundle = new Bundle();
        mContent.saveState(webViewBundle);
    }

    private class FetchContent extends AsyncTask<String, String, String> {

        private JSONParser jsonParser;
        private String content;

        @Override
        protected String doInBackground(String... params) {
            jsonParser = new JSONParser();
            List<NameValuePair> parametre = new ArrayList<NameValuePair>();
            parametre.add(new BasicNameValuePair("post_id", mArticleId));
            JSONObject jObj = jsonParser
                    .getJSONFromUrlNonHtml(
                            "http://www.androidaci.net/api/get_post/",
                            parametre, "GET");
            try {
                JSONObject post = jObj.getJSONObject("post");
                content = post.getString("content");
            } catch (JSONException e) {
                e.printStackTrace();
            }
            return content;
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            mContent.loadDataWithBaseURL("", removePlayStore(result),
                    "text/html", "UTF-8", "");

        }
    }

我以HTML格式加载网站上的内容，我用JSOUP对其进行了一些修改，然后我展示了它，它首先尝试使用，但是在轮换更改后我松开了状态。我怎么能保存这个？

为了使此代码有效，我需要从onCreate

中删除此行

this.setRetainInstance(true);

Android片段中的Android旋转webview导致不记住状态
