EditTextPreference崩溃

Question

我已经创建了一个PreferenceScreen，它工作得很好，但是最近我添加了两个EditTextPreferences，似乎出了什么问题。只要单击EditTextPreference，应用程序就会崩溃。

这是我的preferences.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory android:title="@string/title_telephone">

        <SwitchPreference
            android:defaultValue="@string/default_checkbox_telephone_recording"
            android:key="checkbox_preference_telephone_recording"
            android:summary="@string/preference_recording_summary"
            android:title="@string/checkbox_telephone_recording" />

        <SwitchPreference
            android:defaultValue="@string/default_checkbox_telephone_accel"
            android:key="checkbox_preference_telephone_accel"
            android:summary="@string/preference_accel_summary"
            android:title="@string/checkbox_telephone_accel" />

    </PreferenceCategory>
    <PreferenceCategory android:title="Allgemeine Informationen">

        <EditTextPreference
            android:defaultValue="none"
            android:clickable="false"
            android:key="textfield_preference_client_ID"
            android:title="@string/textbox_client_ID_title"
            android:summary="0" />
        <EditTextPreference
            android:defaultValue="none"
            android:clickable="false"
            android:key="textfield_preference_version_ID"
            android:title="@string/textbox_version_ID_title"
            android:summary="@string/version_ID" />
    </PreferenceCategory>
</PreferenceScreen>

下面是堆栈跟踪

有人能帮我吗？我没能解决这个问题。我不希望EditTextPreferences是可点击的，但是在没有这个xml参数的情况下，我尝试了它，它会崩溃。

更新

当我用EditTextPreference替换Preference时，一切都很好。但是，这并不能真正解释为什么我的配置会遇到麻烦。

因为您尝试将链接放在不存在的资源上，所以出现了问题。这里可能有问题: android:summary="0“。尝试在@string资源上更改值"0“
