Known Direct Subclasses EmojiAppCompatButton EmojiAppCompatButton AppCompatButton widget enhanced with emoji capability by using EmojiTextViewHelper.

A Button which supports compatible features on older versions of the platform, including:

• Allows dynamic tint of its background via the background tint methods in androidx.core.view.ViewCompat.
• Allows setting of the background tint using R.attr#backgroundTint and R.attr#backgroundTintMode.
• Allows setting of the font family using android.R.attr#fontFamily

This will automatically be used when you use Button in your layouts and the top-level activity / dialog is provided by appcompat. You should only need to manually use this class when writing custom views.
