Here's one way to do it, using the support library:

<androidx.appcompat.widget.AppCompatTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:breakStrategy="balanced" 
        android:gravity="center_horizontal"
        android:maxLines="1"
        android:text="Hello world" 
        android:textSize="300sp" 
        app:autoSizeTextType="uniform"
        tools:targetApi="o"/>

The android:breakStrategy allows making the text go to the next line nicely, instead of the default behavior which might break the words.

In gradle, use this:

implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
implementation 'com.google.android.material:material:1.0.0-beta01'

Or this:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'

Note that it's recommended to set layout restrictions on the TextView (width and/or height), to make sure you will get it right. All depends on your use case.
