java.lang.IllegalStateException：使用抽屜時尚未創建的內容視圖

Question

我爲我的android應用程序使用抽屜列表。 有問題。 當我點擊隨機（非常快），然後我得到forcestop和java.lang.IllegalStateException: Content view not yet created顯示在日誌。 我米使用片段

我M還得到以下運行時錯誤 在android.support.v4.app.ListFragment.ensureList（ListFragment.java:32

這裏是在我的代碼一個部分從抽屜表選擇和

Fragment home = new Home(); 
    Fragment feeds = new Feeds_ListView(); 

.....

private void selectItem(int position) 
{ 

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
    switch (position) 
    { 

     case 0: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, feeds); 

      break; 
     case 1: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, NewPostFragment); 
      break; 
     case 2: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, SearchDetailsFragment); 
      break; 
     case 3: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, feeds1); 
      break; 
     case 4: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, UserDetailsFragment); 
      break; 
     case 5: 
      setTitle(title[position]); 
      ft.replace(R.id.content_frame, FBActivity); 
      break; 
    } 
    ft.commit(); 
    mDrawerList.setItemChecked(position, true); 
    setTitle(title[position]); 
    mDrawerLayout.closeDrawer(mDrawerList); 
} 


@Override 
protected void onPostCreate(Bundle savedInstanceState) 
{ 
    super.onPostCreate(savedInstanceState); 
    mDrawerToggle.syncState(); 
} 

@Override 
public void onConfigurationChanged(Configuration newConfig) 
{ 
    super.onConfigurationChanged(newConfig); 
    mDrawerToggle.onConfigurationChanged(newConfig); 
} 

@Override 
public void setTitle(CharSequence title) 
{ 
    mTitle = title; 
    getSupportActionBar().setTitle(mTitle); 
} 

這裏是Feeds_ListView（）的一部分;

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
    context=container.getContext(); 
    rootView = inflater.inflate(R.layout.feeds_listview_layout, container, false); 


    list = (ListView) rootView.findViewById(android.R.id.list); 
    mRelativeLayout=rootView.findViewById(R.id.mRelativeLayout); 

    saveProgress =(ProgressBar) rootView.findViewById(R.id.loadpost); 
    saveProgress.setVisibility(View.INVISIBLE); 



    userAdapter = new CustomListAdapter(getActivity(), R.layout.feeds_listview_item,userArray); 





    mRelativeLayout.setVisibility(View.GONE); 

    list.setItemsCanFocus(false); 
    list.setAdapter(userAdapter); 
    return rootView; 

} 





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

    SharedPreferences settings =getActivity().getSharedPreferences("newdatabase",0); 

     String user_id=settings.getString("user_id", "--"); 

     if(user_id.equals("--") || user_id.equals("")) 
     { FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();   

      ft.replace(R.id.content_frame, FBActivity); 
      ft.commit(); 
     }else{ 
       new Onscrollasync().execute(); 

      ((PullToRefresh_Master) getListView()).setOnRefreshListener(new OnRefreshListener() 
      { 
       @Override 
       public void onRefresh() 
       { 
        new Onscrollasync().execute(); 
       } 
      }); 
     } 


} 

Answer 1

的問題是，在該片段Home的代碼，您在onCreateView寫道。將您的onCreateView()中的代碼移至onActivityCreated()或onViewCreated()。 StackOverlfow上有幾個類似的問題，如here。

Answer 2

嘗試，而不是膨脹的容器，試着用虛增您的視圖，而不容器即

rootView = inflater.inflate(R.layout.feeds_listview_layout,null); 

讓我知道這是否正常工作。
