使用保留片段會導致錯誤膨脹SupportMapFragment？

Question

我的地圖一直在工作，直到我從本教程"Handling The Change"添加了RetainedFragment。

PlaceholderFragment在SplashScreenActivity.java

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

：

充氣包含與類com.google.android.gms.maps.SupportMapFragment片段的佈局時，會出現錯誤res/layout/fragment_splash_screen.xml

<fragment 
    android:id="@+id/app_search_map_fragment" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.SupportMapFragment" /> 

錯誤：

android.view.InflateException: Binary XML file line #18: Error inflating class fragment

我沒有IDEIA什麼VS SupportMapFragment RetainedFragment之間的關係，但只有當我使用RetainedFragment出現此錯誤。

// find the retained fragment on activity restarts 
FragmentManager fm = getSupportFragmentManager(); 
dataFragment = (RetainedFragment) fm.findFragmentByTag("data"); 

// create the fragment and data the first time 
if (dataFragment == null) { 
    // add the fragment 
    dataFragment = new RetainedFragment(); 
    fm.beginTransaction().add(dataFragment, "data").commit(); 
} 

的簡化版，應用程序崩潰，如果我刪除此行

fm.beginTransaction().add(dataFragment, "data").commit(); 

我已經創建了一個包含有一個簡單的佈局與SupportMapFragment和RetainedFragment一個簡單的活動一個簡單的項目。

我不知道如何與您的RetainedFragment，這是奇怪的。

但它看起來像你的問題是有關Having an issue with GoogleMap v2 crashing app on orientation change。

您創建一個佔位符片段，然後加載XML格式的子片段。看起來這不起作用，並且只能動態添加子片段。試試看看它是否解決了你的問題。
