Android SupportMapFragment沒有創建視圖錯誤

Question

我真的很難找出這個奇怪的問題。在我的android應用程序中，我有一個包含支持地圖片段的片段。谷歌地圖工作正常，當GPS打開，這個片段創建罰款。但是，當GPS關閉時，應用程序甚至不會實例化，它只會在打開時崩潰。

這裏是堆棧跟蹤：

這是我的片段onCreateView

@Override

    super.onCreateView(inflater, container, savedInstanceState); 

    this.activity = this.getActivity(); 

    ActionBar ab = getActivity().getActionBar(); 
    if (ab.getNavigationMode() == ActionBar.NAVIGATION_MODE_STANDARD) { 
     ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 
    } 

    ab.setDisplayHomeAsUpEnabled(false); 

    checkForGooglePlayServices(); 

    View view = inflater.inflate(R.layout.fragment_trackinfo, container, false); 

    setUpMapIfNeeded(); 
    return view; 
} 

任何幫助將不勝感激

由於this answer，我設法解決了這個問題。

您需要在您的佈局XML來改變fragment關鍵字FrameLayout。
