的Android ListPreference關閉我的申請下來

好傢伙我現在面臨一個問題，我的Android應用：我添加了一個設置活動，我的應用程序的列表中優先應用程序停止這裏的首選項的XML，當點擊：的Android ListPreference關閉我的申請下來

<PreferenceCategory android:title="Settings"> 

    <EditTextPreference 
     android:selectAllOnFocus="true" 
     android:title="Player Name" 
     android:key="userName" 
     android:defaultValue="default" 
     android:summary="Enter Player Name " /> 
    <ListPreference 
     android:key="listPref" 
     android:dialogTitle="Choose a a number" 
     android:entries="@array/life_list" 
     android:entryValues="@array/life_list" 
     android:title="Number of attempts" /> 
</PreferenceCategory>

這裏的@陣列/ life_list：

<?version="1.0" encoding="utf-8"?> 
<resources> 
<integer-array name="life_list"> 
    <item>1</item> 
    <item>2</item> 
    <item>3</item> 
</integer-array>

這裏的調試報告：

發表您的Java代碼。 –

的問題是：

<?version="1.0" encoding="utf-8"?> 
<resources> 
    <integer-array name="life_list"> // string-array 
    <item>1</item> 
    <item>2</item> 
    <item>3</item> 
    </integer-array> // string-array

我改串整數和問題得到解決
