How to format xml string?

Question

I am tring to use plurals

<plurals name="days">
  <item quantity="one"  >%1$d = @string/day_one</item>
  <item quantity="few"  >%1$d = @string/day_few</item>
  <item quantity="many" >%1$d = @string/day_many</item>
  <item quantity="other">%1$d = @string/day_many</item>
</plurals>

Where @string/day_* referes to diffrent day translations, however I get:

0 = @string/day_one

Answer 1

you can't do that. You have to move %1$d = to the single string, and only then you can reference the single string. Concatenation does not work

Answer 2

You can reference string on xml but it has to be the entire string like this:

<string name="message_title">@string/app_name</string>

Answer 3

you can try this

<plurals name="days">
    <item quantity="one">%d day</item>
    <item quantity="other">%d days!</item>
</plurals>
