Determining when the android MediaController view becomes visible

Question

I'm using the MediaController class to anchor the video controller views to my VideoView. When the VideoView is clicked,the controller becomes visible for some few seconds then leaves the screen. Is there a listener in the MediaController that allows us know the moment it becomes visible or not?

Answer 1

android.widget.MediaController is inherited from android.view.View, so that you can add android.view.View.addOnAttachStateChangeListener for attach state changes.

mediaController.addOnAttachStateChangeListener(object : View.OnAttachStateChangeListener {
    override fun onViewAttachedToWindow(view: View?) {
    }

    override fun onViewDetachedFromWindow(view: View?) {
    }
})
