如何从fxml文件中的xml文件读取值？

Question

I am newbie to JavaFX, and as a similar way that is done in Android Studio, I would like to have a file called strings.xml where I can store some resources that can be read from an fxml file . For example, if I have the following code in strings.xml :

<resources>
    <string name="app_name">My App Name</string>
</resources>

I would like to do something like this in the fxml file:

text="@string/app_name"

How is it possible to achieve that?

Yes, it is possible to use internationalized strings within FXML files in a way similar to Android's resources. There are some differences:

1. The resource files are .properties files instead of .xml . The variables are defined in a different way too:

    variable.name_1=Hello variable.name_2=World 

   (Note missing <resource> tags, it is just plain [var_name]=[value] ).

2. To reference a string in a FXML file, you use a % instead of an @string/ . For example:

    <Button fx:id="button1" text="%variable.name_1" /> 

That's it. I recommend searching for ResourceBundle as this explains how the property files should be named for the right language to be chosen. Also, that bundle can be used for adding internationalized variables to your code as well.
