用户单击一个按钮，该按钮将显示一个片段对话框，该对话框将如下所示的片段展开：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

        View view = getActivity().getLayoutInflater().inflate(
                R.layout.monday_fragment, null);
        builder.setView(view).setTitle("Homework Due Monday")
                .setNegativeButton("Dismiss", null);

        AlertDialog dialog = builder.create();
        dialog.show();

下面是指定布局的xml (monday_fragment.xml)，其中包含对要膨胀的片段的引用：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    >

    <fragment
        android:id="@+id/monday_fragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment"
        android:layout_centerHorizontal="true"/>

</RelativeLayout>

然后，片段对话框中的片段在其OnCreateView中膨胀自己的布局：

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

        swipe = inflater.inflate(R.layout.day_homework_fragment, container,
                false);

        lView = (ListView) swipe.findViewById(R.id.listView1);

        progress = (ProgressBar) swipe.findViewById(R.id.progress);

        lView.setVisibility(View.GONE);

        return swipe;

    }

下面是在片段中放大的"day_homework_fragment.xml“布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:layout_gravity="center"
    android:background="@color/light_background">

    <ProgressBar
        android:id="@+id/progress"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center" />

    <ListView
        android:id="@+id/listView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
         android:background="#ffffff"
         android:divider="@null"
        android:dividerHeight="0dp"
         >
    </ListView>

           <TextView 
           android:id="@+id/emptyView"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:text="As of now, no homework due this day"
           android:padding="30dp" 
           android:textSize="16sp"/>

</LinearLayout>

这是它抛出的错误的日志，我已经尝试了这个post和这个post，但都没有修复这个问题。

编辑:我刚刚意识到这是在我从eclipse迁移到Android Studio之后才开始发生的。也许这跟这件事有关？可能所有的片段引用都是乱七八糟的？

android

android-fragments

illegalstateexception

inflate-exception

您的日志指向第10行的事实意味着这里的xml声明是一个问题，就像fragment在第10行所说的那样：

 android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment"

我会在这里仔细检查这个引用，看看它是否指向您为片段保存java类的正确位置。

另外，检查您的MondayFragment类是否扩展了正确的片段类。换句话说，如果您使用的是support库，则需要扩展support库片段类，而不是普通的片段类。

如果所有其他方法都失败了，您始终可以通过编程方式添加一个片段：http://developer.android.com/training/basics/fragments/fragment-ui.html

xml：我发现您目前正在使用以下代码扩展您的：

View view = getActivity().getLayoutInflater().inflate(
                R.layout.monday_fragment, null);

既然你是在一个片段中膨胀它，你能不能简单地说：

View view = inflater.inflate(R.layout.monday_fragment, null,
                false);

您不能将片段放入标准AlertDialog中。您必须创建一个DialogFragment实现来将片段添加到对话框中。原因很简单，因为标准片段会试图将自己附加到相应活动的根窗口，但当AlertDialog在根窗口上有一个单独的窗口时，情况并非如此。AlertDialog不能包含DialogFragment甚至Fragment。尝试将您的AlertDialog代码更改为DialogFragment实现。

我认为这段代码是可疑的：

 View view = getActivity().getLayoutInflater().inflate(
            R.layout.monday_fragment, null);

xml的第一个参数应该是xml文件名，而不是片段ID。也许您需要使用xml R.layout.day_homework_fragment。

我知道这些身份证很让人困惑。只有像findViewById()这样的方法才指向UI。
