Android SupportMapFragment没有创建视图错误

Question

我真的很难找出这个奇怪的问题。在我的android应用程序中，我有一个包含支持地图片段的片段。谷歌地图工作正常，当GPS打开，这个片段创建罚款。但是，当GPS关闭时，应用程序甚至不会实例化，它只会在打开时崩溃。

这里是堆栈跟踪：

这是我的布局XML：

    map:uiTiltGestures="true" 
    map:uiZoomControls="true" 
    map:uiZoomGestures="true" /> 


</LinearLayout> 

这是我的片段onCreateView

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

任何帮助将不胜感激

由于this answer，我设法解决了这个问题。

您需要在您的布局XML来改变fragment关键字FrameLayout。
