我的應用程序中的所有文本都在res \ values \ strings.xml中。
我應該添加第二種語言。
該應用程序應檢測Android的語言，然後選擇適當的語言。
是否有可能增加一種語言避免改變引用strings.xml中，如下面：什麼是嚮應用程序添加第二語言的最佳方式
sensor.client.R.string.operationResult_communicationError
或
<TextView
android:text="@string/common_please_wait"
有什麼建議嗎？
看看this鏈接。總之，您應該爲您的應用支持的每種語言提供多個strings.xml。
res中包含string.xml的默認「values」文件夾，右邊。現在，如果您希望自己的應用支持其他語言，請創建一些其他「值」文件夾。
例子：
如果你希望你的應用程序，以支持「Rusian語言」，然後用名稱「值る」這也將包含string.xml創建文件夾。並確保無論您在值文件夾的string.xml中使用的字符串名稱是否與您在values-ru文件夾的string.xml文件中使用的名稱相同。
例如
在值文件夾的：<string name="submit">Submit</string> 在值儒文件夾的：<string name="submit">Представить</string>

需要值-XX爲每種語言文件夾，然後這些文件夾中的strings.xml文件。在eclipse中，所有這些值-xx文件夾分別顯示在/ res文件夾中。在android studio中，你點擊值，它會顯示所有的值 - xx文件夾。 分步教程： https://www.youtube.com/watch?v=og3BqpZMw7Q
