Android IllegalStateException:在onSaveInstanceState之后无法执行此操作-在屏幕旋转之后

我也得到了一个精确的背景，这里给出的解决方案不起作用

下面是代码：应该是测试的工作代码；我希望如此

MainActivity.java

public class MainActivity extends FragmentActivity {
  final static int INIT_NETWORK_DONE = 1;
  final static int EXIT_APPLICATION = -1;

  private Site site = new Site(this);
  private WifiManager wifi = null;
  Handler mHandler = null;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    site.setUrls();

    if (savedInstanceState == null) {
        FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
        fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        fragmentTransaction.replace(R.id.frame_container, new Fragment_init(site)).commit();

    }
  }
   . . .
  @Override
  public void onSaveInstanceState(Bundle saveInstanceState) {

       //super.onSaveInstanceState(saveInstanceState);
  }
}

Fragment_init.java

public class Fragment_init extends Fragment {
    Fragment fragment = null;
    private InitTask mInitTask = null;
    // Taille maximale du téléchargement
    public final static int MAX_SIZE = 100;
    // Identifiant de la boîte de dialogue
    public final static int ID_DIALOG = 0;
    public final static int DO_INIT_WIFI = 1;

    private Site site = null;


    public Fragment_init() {
    }    

    public Fragment_init(Site _site) {
        site = _site;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_init, container, false);

        return rootView;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        if (savedInstanceState == null) {
            Animation animation = AnimationUtils.loadAnimation(getActivity().getApplicationContext(), R.animator.welcome_anim);
            ImageView logoSite = (ImageView)getActivity().findViewById(R.id.imageAvenArmand);
            logoSite.startAnimation(animation);

                // Do the init
                mInitTask = new InitTask(Fragment_init.this, site, getFragmentManager());
                // On l'exécute
                mInitTask.execute(0);
        }
    }

    // L'AsyncTask est bien une classe interne statique
    static class InitTask extends AsyncTask<Integer, Integer, Integer> {
        // Référence faible à l'activité
        private Fragment_init mActivity = null;
        private Site site = null;
        Context context = null;
        private FragmentManager fragmentManager = null;

        public InitTask (Fragment_init pActivity, Site pSite, FragmentManager _fragmentManager) {
            mActivity = pActivity;
            context = mActivity.getActivity();
            site = pSite;
            fragmentManager = _fragmentManager;
          }

        @Override
        protected void onPreExecute () {
        }

        @Override
        protected void onPostExecute (Integer result) {
            if(result != 1) {
                AlertDialog.Builder alertDialog = new AlertDialog.Builder(mActivity.getActivity());
                alertDialog.setTitle(R.string.label_titleAlertInit);
            } else {
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
                fragmentTransaction.replace(R.id.frame_container, new Fragment_selectLanguage(site)).commitAllowingStateLoss();
            }
        }

        @Override
        protected Integer doInBackground (Integer... arg0) {
            URL url = null;
            BufferedInputStream buf;
            ArrayList<Language> languages = null;

            try {
                Thread.sleep(3000);
            } catch (InterruptedException e) {

            }
            return 1;
        }

        @Override
        protected void onProgressUpdate (Integer... prog) {
        }

        @Override
        protected void onCancelled () {
        }

        private int processStream(InputStream inputStream) {
            // Création du parser XML
            XmlPullParserFactory factory;
            int lineNumber = 0;

            return (1);

        }
    }

    @Override
    public void onSaveInstanceState(Bundle saveInstanceState) {
        //super.onSaveInstanceState(saveInstanceState);

    }
}

然后我在下一个片段的onCreateView中调用它：

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

还有其他想法吗？

使用commitAllowingStateLoss而不是commit

if (savedInstanceState == null) {
    FragmentTransaction fragmentTransaction =getSupportFragmentManager().beginTransaction();
    fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
    fragmentTransaction.replace(R.id.frame_container, new Fragment_init(site)).commitAllowingStateLoss();

}

您应该看到这个关于如何避免该异常的博客：

因此，我使用下面介绍的wonderfull消息处理程序实现解决了我的问题：

Thx给Akagami，他在帖子上指出了我

问候，

！？！正如你所看到的，这是我所做的，没有任何改变。从你提供的代码片段来看，这不是你正在做的。或者你是说你试图使用commitAllowingStateLoss，但同样的异常仍然发生？是的，没错，在读了几篇关于这个主题的文章后，我试图使用commitAllowingStateLoss，但我还是得到了异常。嗨，Akagami，有趣的是，让我觉得没有真正的解决方案，事实上，我检查了一下，我通常意识到onresume之后的commit是在活动恢复后调用的，但是仍然会抛出异常。所以我真的不知道该怎么办。

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

if (savedInstanceState == null) {
    FragmentTransaction fragmentTransaction =getSupportFragmentManager().beginTransaction();
    fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
    fragmentTransaction.replace(R.id.frame_container, new Fragment_init(site)).commitAllowingStateLoss();

}
