At the moment, I have the simplest one-page application with one data entry field. I looked at a lot of examples, but I could not find the answer to my question: how do I add hint text at the bottom of the input field?

Add a Textview and Constraint it below your Edittext
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="60dp"

<TextView
android:id="@ id/hint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:text="user"
android:textColor="@android:color/holo_red_dark"
android:textSize="14sp"
app:layout_constraintStart_toStartOf="@ id/editTextUserId"
app:layout_constraintTop_toBottomOf="@ id/editTextUserId" />
</androidx.constraintlayout.widget.ConstraintLayout>
Then if you want to show/hide it base on user interaction you can do something like this in your activity
editTextUserId.setOnFocusChangeListener((view, b) -> {
if(b){hint.setVisibility(View.VISIBLE);}
else {hint.setVisibility(View.INVISIBLE);}
});
