I checked the official document, getFont this method is added after the api 27, and need to add com.android.support:support-compat:27.0.0 in build.gradle file. It belongs to ResourcesCompat

ResourcesCompat

android doc getFont

Try this

 implementation 'com.android.support:recyclerview-v7:27.0.2'
 implementation 'com.android.support:appcompat-v7:27.0.2'

and this

buildToolsVersion 27.0.2
compileSdkVersion 27.0.2
