Accessing String Resources with Placeholders Using Data Binding in Layout XML

This article was translated from Japanese by Claude Code.

As described in the official reference:

<string name="self_introduction">My name is %1$s</string>

Suppose you have a string resource defined like this. If you want to bind it to a TextView’s text field using Data Binding in Layout XML, previously it seemed like only this way of writing worked:

android:text="@{String.format(@string/self_introduction, user.name)}"

But upon re-checking, you can also write:

android:text="@{@string/self_introduction(user.name)}"

Just a note.
