Autosize textview is not working

Hi I am using autosize textview in my android application. My app minSdkVersion is 19 so I am using support library.

https://developer.android.com/guide/topics/ui/look-and-feel/autosizing-textview.html

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.app.android.registration.RegistrationActivity"
    tools:ignore="missingPrefix">

    <include
        android:id="@+id/toolbar_registration_layout"
        layout="@layout/toolbar" />

    <TextView
        android:id="@+id/textview_registration_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fontFamily="@font/lato_medium"
        android:padding="8dp"
        android:text="@string/registration_title"
        app:autoSizeTextType="uniform"
        app:layout_constraintTop_toBottomOf="@id/toolbar" />


</android.support.constraint.ConstraintLayout>

enter image description here

Does anyone know why it is not resizing as there is lot of space available on right side of it.

In my case using only fixed dimension or match_parent didn't work. I had to add "maxLines=1" and "lines=1". Don't know why is this not made obvious in the documentation.

Change your android:layout_height="wrap_content" to a specific value

Like : android:layout_height="200dp"

You can read in documentation -:

Note: If you set autosizing in an XML file, it is not recommended to use the value "wrap_content" for the layout_width or layout_height attributes of a TextView. It may produce unexpected results.

enter image description here

So, you must pass a fixed value to android:layout_height of TextView

Hope, this will help you
