Using strings.xml w/ Android
提问by basemansix8
I've looked and tried many things but it seems my App isn't getting the values for strings in strings.xml. It actually seems like it's passing blank. I think there's an issue initializing.
我已经查看并尝试了很多东西，但似乎我的应用程序没有获取 strings.xml 中字符串的值。它实际上似乎正在传递空白。我认为初始化存在问题。
strings.xml
字符串.xml
<string name="itb_cityID">2</string>
<string name="itb_city">New York</string>
constants.java excerpt:
constants.java 摘录：
public class ConstantData {
public static String cityID="2";
public static String city="New York";
How do I set cityID = R.strings.itb_cityIDand city=itb_citythe correct way?
我如何设置cityID = R.strings.itb_cityID和city=itb_city正确的方法？

String yourString = Context.getResources().getString(R.string.your_string);
String yourString = Context.getResources().getString(R.string.your_string);
Note: You can't use Contextstatically. If you're inside an Activity, simply use thisor call getResources()directly. Otherwise you'll need to obtain a handle to your application's context via getApplicationContext().
注意：不能Context静态使用。如果您在 Activity 中，只需直接使用this或调用getResources()即可。否则，您将需要通过 获取应用程序上下文的句柄getApplicationContext()。

This example could be useful
这个例子可能有用
XML file saved at res/values/strings.xml:
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello">Hello!</string> </resources>This layout XML applies a string to a View
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" />This application code retrieves a string:
String string = getString(R.string.hello);You can use either getString(int) or getText(int) to retrieve a string. getText(int) will retain any rich text styling applied to the string.
保存在 res/values/strings.xml 的 XML 文件：
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello">Hello!</string> </resources>此布局 XML 将字符串应用于视图
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" />此应用程序代码检索字符串：
String string = getString(R.string.hello);您可以使用 getString(int) 或 getText(int) 来检索字符串。getText(int) 将保留应用于字符串的任何富文本样式。

Have you checked that the entire project is error free. If it is not there may be an error that is preventing R.java from being updated with your string. You could try to "Clean" you projected from the "Project" menu. That may work. Also, I can't see why you would have to use Context., usually you should be able to call getResources().directly (in some situations even this is unnecessary). A good thing to look for is if the string you have declared in your strings.xml file is recognised as a declared string.
您是否检查过整个项目没有错误。如果不是，则可能存在阻止 R.java 使用您的字符串更新的错误。您可以尝试从“项目”菜单中“清理”您投影的内容。那可能会奏效。另外，我不明白为什么您必须使用Context.，通常您应该能够getResources().直接调用（在某些情况下甚至这是不必要的）。一个好消息是，您在 strings.xml 文件中声明的字符串是否被识别为声明的字符串。
