我有这个问题与ViewPager，当手动拖动到下一个页面，TalkBack是确定的，但当假拖动点击按钮，其中有一个假拖动代码，然后TalkBack的ViewPager读取位置从页面之前的当前页面.所以我关闭了TalkBack的假拖动，并创建了新的TalkBack事件：

animator.addListener(object : Animator.AnimatorListener {
        override fun onAnimationStart(animation: Animator?) {
            isFakeDrag = true
            viewPager.importantForAccessibility = View.IMPORTANT_FOR_ACCESSIBILITY_NO
            viewPager.beginFakeDrag()
        }
        override fun onAnimationEnd(animation: Animator?) {
            viewPager.endFakeDrag()
            viewPager.importantForAccessibility = View.IMPORTANT_FOR_ACCESSIBILITY_YES
            isFakeDrag = false
        }
        override fun onAnimationCancel(animation: Animator?) { /* Ignored */ }
        override fun onAnimationRepeat(animation: Animator?) { /* Ignored */ }
    })

以及

viewPager.registerOnPageChangeCallback( object : ViewPager2.OnPageChangeCallback() {
        override fun onPageScrolled(
            position: Int,
            positionOffset: Float,
            positionOffsetPixels: Int
        ) {
            //some code
        }

        override fun onPageSelected(position: Int) {
            super.onPageSelected(position)
            if(isFakeDrag) {
                val event = AccessibilityEvent.obtain()
                event.eventType = AccessibilityEvent.TYPE_ANNOUNCEMENT
                val positionString = //create a string to be announced by TalkBack
                positionString.also { event.text.add(it) }
                val accessibilityManager = requireContext().getSystemService(Context.ACCESSIBILITY_SERVICE) as AccessibilityManager
                accessibilityManager.sendAccessibilityEvent(event)
            }
        }
    })
