如何将视图(TextView)约束到progressBar当前进度？

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ProgressBar
        android:id="@+id/progressBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@+id/textView"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintHorizontal_chainStyle="packed" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toBottomOf="@+id/progressBar"
        app:layout_constraintStart_toStartOf="@+id/progressBar"
        app:layout_constraintEnd_toEndOf="@+id/progressBar" />

</androidx.constraintlayout.widget.ConstraintLayout>

ProgressBar progressBar = findViewById(R.id.progressBar);
TextView textView = findViewById(R.id.textView);

int progress = progressBar.getProgress();
textView.setText(String.valueOf(progress));
