adjust TextView size to new text

I have a textview between 2 other views inside a ConstraintLayout. I set the text of the second one in the onViewCreated of my Fragment and later change it after some user input. The first text works fine, but when i change it later i would expect its size to change with it, which of course would cause the view on its right to move a bit. Instead the new text breaks down into 2 lines, when it's longer than the original... How can i achieve that? Here are the 3 Views:

<TextView
    android:id="@+id/label"
    android:layout_width="0dp"
    android:layout_height="35dp"
    android:layout_marginStart="24dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="24dp"
    android:fontFamily="@font/hevetica_font"
    android:gravity="center_vertical"
    android:paddingStart="4dp"
    android:paddingEnd="4dp"
    android:text="@string/lbl"
    android:textColor="@color/FlatWhite"
    android:textSize="19sp"
    android:textStyle="bold"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@id/topView" />

<TextView
    android:id="@+id/text"
    android:layout_width="0dp"
    android:layout_height="35dp"
    android:layout_marginStart="24dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="24dp"
    android:fontFamily="@font/hevetica_font"
    android:gravity="center_vertical"
    android:paddingStart="4dp"
    android:paddingEnd="4dp"
    android:text=""
    android:textColor="@color/FlatWhite"
    android:textSize="19sp"
    android:textStyle="bold"
    app:layout_constraintStart_toEndOf="@id/label"
    app:layout_constraintTop_toBottomOf="@id/topView" />

<Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="24dp"
    app:layout_constraintStart_toEndOf="@id/label"
    app:layout_constraintTop_toBottomOf="@id/topView"
    android:text="change"
    />

and in the java code i change text using textView.setText(text);

If I understood you correctly, you want the text in the second view not to be split into 2 lines, you need to make the following changes:

 <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <TextView
        android:id="@+id/label"
        android:layout_width="0dp"
        android:layout_height="35dp"
        android:layout_marginStart="24dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="24dp"
        android:gravity="center_vertical"
        android:paddingStart="4dp"
        android:paddingEnd="4dp"
        android:textSize="19sp"
        android:textStyle="bold"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/text"
        android:layout_width="0dp"
        android:layout_height="35dp"
        android:layout_marginStart="24dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="24dp"
        android:gravity="center_vertical"
        android:paddingStart="4dp"
        android:paddingEnd="4dp"
        android:maxLines="1"
        android:textSize="19sp"
        android:textStyle="bold"
        app:layout_constraintStart_toEndOf="@id/label"
        app:layout_constraintTop_toTopOf="parent" />

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="24dp"
        app:layout_constraintStart_toEndOf="@id/text"
        app:layout_constraintTop_toTopOf="parent"
        android:text="change" />

</androidx.constraintlayout.widget.ConstraintLayout>
