Granularity

In Java:

Call the setAutoSizeTextTypeUniformWithConfiguration() method:

setAutoSizeTextTypeUniformWithConfiguration(int autoSizeMinTextSize, int autoSizeMaxTextSize, int autoSizeStepGranularity, int unit)

In XML:

Use the autoSizeMinTextSize, autoSizeMaxTextSize, and autoSizeStepGranularity attributes to set the auto-sizing dimensions in the layout XML file:

<TextView android:id=”@+id/autosizing_textview_presetsize” 
        android:layout_width=”wrap_content” 
        android:layout_height=”250dp” 
        android:layout_marginLeft=”0dp” 
        android:layout_marginTop=”0dp” 
        android:autoSizeMaxTextSize=”100sp” 
        android:autoSizeMinTextSize=”12sp” 
        android:autoSizeStepGranularity=”2sp” 
        android:autoSizeText=”uniform” 
        android:text=”Hello World!” 
        android:textSize=”100sp” 
        app:layout_constraintLeft_toLeftOf=”parent” 
        app:layout_constraintTop_toTopOf=”parent” />
