It is possible to last a variable in Strings.xml

Question

I’m trying to get a string from the.xml string to replace a field on the screen, but I’ve been searching and I’m not being able to use it as a variable

xml string.

<string name="nome">%1$s</string>

java class.

Resources res = getResources();
        String text = String.format(res.getString(R.string.nome), username);

xml layout.

<TextView
        android:id="@+id/nome1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:text="@string/nome"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

Upshot:

I don’t know if that’s exactly what you’re thinking, but you can do something like this:

Resources res = getResources();
String text = res.getString(R.string.nome, username);
textView.setText(text);

Taking its string as an example, this has no usefulness.

An example where it can be useful is in the use of strings per language:

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

and

<string name="nome">O meu nome é %1$s</string>

The initial part is chosen automatically, according to the language, and then the name.
