Known Direct Subclasses EmojiAppCompatTextView EmojiAppCompatTextView AppCompatTextView widget enhanced with emoji capability by using EmojiTextViewHelper.

A TextView 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 androidx.appcompat.R.attr#backgroundTint and androidx.appcompat.R.attr#backgroundTintMode.
• Supports auto-sizing via androidx.core.widget.TextViewCompat by allowing to instruct a TextView to let the size of the text expand or contract automatically to fill its layout based on the TextView's characteristics and boundaries. The style attributes associated with auto-sizing are androidx.appcompat.R.attr#autoSizeTextType, androidx.appcompat.R.attr#autoSizeMinTextSize, androidx.appcompat.R.attr#autoSizeMaxTextSize, androidx.appcompat.R.attr#autoSizeStepGranularity and androidx.appcompat.R.attr#autoSizePresetSizes, all of which work back to Ice Cream Sandwich.

This will automatically be used when you use TextView 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.
