Textview: adjust font size to match parent

Question

Is it possible to set font size to automatically match_parent?

My TextView is already width/height="match_parent" but the font size is small and doesn't fit to the parent size.

How to do that?

Solution

android:autoSizeTextType="uniform"

add this line to your TextView

Edit: this line will work for api 26 and higher so if you want to use it for api lower than 26 use this

app:autoSizeTextType="uniform"

if adding this line gives you error ignore the error by adding

tools:ignore="MissingPrefix"

The problem is it takes into account only the width of the parent.
