异常发生在setContentView我的OnCreate方法行：

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);

我的活动的 XML 在这里：

<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" />

这很令人沮丧，因为我想做的只是在fragment1and之间切换fragment2，现在我什至无法启动我的应用程序。

我觉得我错过了一些非常简单的东西，我现在看不到它。

根据您的错误消息，Android 似乎找不到 ca.ioto.atractr_v2.ChatFragment 片段的布局。你确定你指定的布局是正确的（拼写和所有）？另外，是否有适合您的屏幕尺寸的布局？（我不知道如果您尝试膨胀当前屏幕尺寸没有布局的布局，Android 是否会引发错误，所以这可能是个问题。）

最后，尝试重建项目（完全清洁 + 构建）。也许构建系统以某种方式搞砸了。
