在 static 初始化程序中是否有一种合理的方式来引用应用程序资源（R.string…）

Question

Is there a sensible, clean way to refer to application resources from static initalizer code in my android classes.

I would specifically like to define an enum which contains the values of some resource strings in its constants.

Here is some pseudo code for the enum

private enum MyEnum {
    Const1(getString(R.string.string1)),
    Const2(getString(R.string.string2)),
    Const3(getString(R.string.string3));

    private String strVal;

    MyEnum(String strVal){
        this.strVal = strVal;
    }
}

This question applies to any kind of static initialization.

I don't think there is a direct way as context is required to load resources. However, what you could do is to provide a method in your enum to get required string once context is available. Something like

private enum MyEnum {
    Const1(R.string.string1),
    Const2(R.string.string2),
    Const3(R.string.string3);

    private int resId;

    MyEnum(int resId){
        this.resId = resId;
    }

    public String resource(Context ctx) {
       return ctx.getString(resId);
    }
}

So you access it like

String val = Const3.resource(context);
