AppCompatSpinner

Kotlin |Java

open class AppCompatSpinner : Spinner, TintableBackgroundView

kotlin.Any
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.AdapterView<android.widget.SpinnerAdapter>
			↳	android.widget.AbsSpinner
				↳	android.widget.Spinner
					↳	androidx.appcompat.widget.AppCompatSpinner

A Spinner 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#buttonTint and R.attr#buttonTintMode.
• Setting the popup theme using R.attr#popupTheme.

This will automatically be used when you use Spinner in your layouts. You should only need to manually use this class when writing custom views.
