Android Resources 为什么 java 认为字符串是整数？

Question

我的每个 XML 首选项都收到以下警告
并且我知道 java 认为我提供的默认值是整数，并且它需要字符串。但是我该如何放置文字字符串呢？
我可以忍受这个警告，因为我知道它是无害的，但如果有一种简单的方法可以纠正它，我会的。

这是 XML:

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

<EditTextPreference
    android:defaultValue="5000"

    android:summary="@string/MAX_MESSAGES_desc"
    android:title="@string/MAX_MESSAGES_title" />

<EditTextPreference

    android:key="@string/VIEW_EDGE_ROWS"

    android:title="@string/AUTOSCROLL_title" />

<CheckBoxPreference

    android:key="@string/SEND_THEN_EXIT"

<Preference
    android:key="@string/DEFAULT_PREFS"
    android:summary="@string/DEFAULT_PREFS_desc"
    android:title="@string/DEFAULT_PREFS_title" />

</PreferenceScreen>

在string.xml中添加这一行

<string name="five_thousand">5000</string>

ans 将它设置为默认值..你可以为其他人设置默认值...

<EditTextPreference
    android:defaultValue="@string/five_thousand"
    android:key="@string/MAX_MESSAGES"
    android:summary="@string/MAX_MESSAGES_desc"
    android:title="@string/MAX_MESSAGES_title" />
