问题描述

如果这是错误的地方要问这个问题，请直接给我一个更合适的位置。

我工作在Eclipse的Andr​​oid项目。当我试图在图形视图来查看preference布局，我不断收到此错误：

I am working on an Android project in Eclipse. When I attempt to view the Preference layout in graphical view, I keep getting this error:

ClassCastException: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup

下面是我的preferences.xml：

Here is my preferences.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory android:title="General">
        <CheckBoxPreference android:title="Show default categories"
            android:defaultValue="true" android:key="default_categories" />
    </PreferenceCategory>
    <PreferenceCategory android:title="Export">
        <EditTextPreference android:key="default_emailaddress"
            android:defaultValue="@string/pref_export_defaultemail"
            android:title="Email Address" android:summary="@string/pref_export_emailsummary" />
        <EditTextPreference android:key="filename_prefix"
            android:defaultValue="@string/pref_export_defaultfilename"
            android:title="Filename Prefix" android:summary="@string/pref_export_filenamesummary" />
    </PreferenceCategory>
</PreferenceScreen>

我不能为我的生活弄清楚它的谈论，我与谷歌搜索没有拿出任何实质性。

I cannot for the life of me figure out what its talking about, my searches with google have not come up with anything substantial.
