唯一的例外是在setContentView行我OnCreate方法存在的:

super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_atractr); 
    newFragment = (FindNearestDevicesFragment)getFragmentManager().findFragmentById(R.id.nearest_fragment); 
    chatFragment = (ChatFragment)getFragmentManager().findFragmentById(R.id.chat_fragment); 
    if (!chordStarted) { 
     initializeChord(); 
    } 
    newFragment.setListener(this); 

而對於我的活動XML是在這裏:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".Atractr" > 

<fragment 
    android:id="@+id/fragment1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    class ="ca.ioto.atractr_v2.FindNearestDevicesFragment" 
    tools:layout="@layout/findnearestdevices_fragment" /> 

<fragment 
    android:id="@+id/fragment2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignLeft="@+id/fragment1" 
    android:layout_alignTop="@+id/fragment1" 
    class="ca.ioto.atractr_v2.ChatFragment" 
    tools:layout="@layout/chat_fragment" /> 

這很令人沮喪,因爲我試圖做的只是在fragment1fragment2之間切換,現在我甚至無法啓動我的應用程序。

我覺得我錯過了一件非常簡單的事情,我現在看不到它。

根據您的錯誤消息,它看起來像Android無法找到您的ca.ioto.atractr_v2.ChatFragment片段的佈局。你確定你指定的佈局是否正確(拼寫和全部)?另外,您的屏幕尺寸是否有佈局? (我不知道Android是否拋出一個錯誤,如果你嘗試膨脹一個沒有當前屏幕尺寸佈局的佈局,所以這可能是個問題。)

最後,嘗試重建項目(完整清潔+構建)。也許構建系統以某種方式搞砸了。

好吧,這是什麼導致我的錯誤。 我在'ChatFragment'類的'OnCreateView'方法中使用'R.id.chat_fragment'而不是'R.layout.chat_fragment' – docaholic
