1. (IMHO lepszy, brak odniesienia do View.VISIBLE/GONE w presenterze)

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <import type="android.view.View"/>
        <variable name="user" type="com.example.UserModel"/>
        <variable name="presenter" type="com.example.UserPresenter"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/user_name"
        android:visibility="@{presenter.shouldShowUserName(user) ? View.VISIBLE : View.GONE}"/>
</layout>

2.

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable name="user" type="com.example.UserModel"/>
        <variable name="presenter" type="com.example.UserPresenter"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/user_name"
        android:visibility="@{presenter.getUserNameVisibility(user)}"/>
</layout>
