在 values-es 文件夹中找不到符号变量答案

【问题标题】：Cannot find symbol variable inside values-es folder在 values-es 文件夹中找不到符号变量
【发布时间】：2020-03-01 03:39:01
【问题描述】：

我正在尝试使用在名为 values-es 的文件夹中创建的字符串数组变量，但是当我尝试调用它时，它会显示 cannot find symbol variable myStrings2。我不确定为什么它不起作用，因为我所做的只是将所有内容从我的strings.xml 复制到我的strings.xml (es) 版本并更改了数组名称。

我正在尝试使用 xml 文件中的 myStrings 和 myStrings2，因此根据系统语言是什么，它将显示适当的语言

我在两个不同的文件中使用了它们，ColorAdapter（在 getElementFromColors 函数中）和PaletteActivity（在 onCreate() 中）并在两个文件中都收到了错误消息

已修复：

通过以下方式解决：

1.将项目模式改为安卓模式

2.右键点击values文件夹

3.将文件命名为字符串

4.选择区域设置作为限定符

5.选择语言

6.点击确定

7.在翻译xml中输入任何内容

它应该将两个strings.xml 文件放在一个strings 文件夹中。与 strings.xml 相比，当 strings.xml (es) 不在单独的文件夹中时，我发现它可以工作

【问题讨论】：

标签： android android-layout

【解决方案1】：

改一下

 if(CurrentLang=="es")

给它

 if(CurrentLang.equals("es"))

【讨论】：

您是否重新启动了您的应用程序？注意：您不需要分离出两个变量字符串数组。在“值-es文件夹中的strings.xml”中设置字符串资源的名称，与值文件夹中的相同string.xml。每当您在设置中更改语言时，Android 系统都会自动检测使用哪种语言的设备并使用正确的资源。
这次没有错误，但是当我在系统设置中更改它时，下拉微调器不会将文本从英文更改为西班牙文
我刚刚为 textview 创建了简单的应用程序支持英语和西班牙文，检查一下你就会知道如何更新你的应用程序：github.com/thanhlv93/MultipleLanguageTest
