Question

不知道出了什么问题。错误日志没有帮助，我也尝试了这里提到的一些解决方案。

这是偏好

<android.support.v14.preference.MultiSelectListPreference
        android:defaultValue="array/pref_hobby_list_default"
        android:dialogTitle="Hobbies"
        android:summary="set your hobbies"
        android:key="hobby_pref"
        android:title="Hobbies"
        android:icon="@drawable/add_favorite"
        android:entries="@array/hobbies"
        android:entryValues="@array/hobby_values"/>

对应的字符串数组

    <string-array name="hobbies">
    <item>Football</item>
    <item>Travelling</item>
    <item>Listening to Music</item>
    <item>Painting</item>
    <item>Watching Movies</item>
    <item>Shopping</item>
    <item>Meeting new people</item>
</string-array>
<string-array name="hobby_values">
    <item>football</item>
    <item>travelling</item>
    <item>listening_to_music</item>
    <item>painting</item>
    <item>watching_movies</item>
    <item>shopping</item>
    <item>meeting_new_people</item>
</string-array>
<string-array name="pref_hobby_list_default">
    <item>football</item>
    <item>travelling</item>
    <item>listening_to_music</item>
    <item>painting</item>
    <item>watching_movies</item>
    <item>shopping</item>
    <item>meeting_new_people</item>
</string-array>

首选项片段：

import android.support.v7.preference.PreferenceFragmentCompat;
public class UserProfilePrefFragment extends PreferenceFragmentCompat {
@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
    // Load the Preferences from the XML file
    addPreferencesFromResource(R.xml.app_preferences);
}
}

您忘记了@登录android:defaultValue="array/pref_hobby_list_default"
