Set AppCompatBackgroundTint programmatically

I've got a TextView that I want to set the background tint of. My app has a minSDK of 19 so I've used AppCompatTextView with the app:backgroundTint parameter used to set the tint declaratively. I would like to programmatically change the tint, but the setSupportBackgroundTintList() method isn't accessible outside the library group. How can I change this value from an Activity?

From the source code for androidx.appcompat.widget.AppCompatTextView:

This should be accessed via

ViewCompat#setBackgroundTintList(android.view.View, ColorStateList)

So, write this:

AppCompatTextView textView = findViewById(R.id.your_text_view)
ColorStateList colorStateList = ContextCompat.getColorStateList(this, R.color.your_state_list);
ViewCompat.setBackgroundTintList(textView, colorStateList);
