Android 约束布局不居中元素

Question

我正在尝试为我的应用制作视频播放器，但是当我旋转手机时，突然所有视频视图都向左移动。这是我的 XML 代码：

现在这应该正确居中视频视图，当我在 android studio 上看到它时它实际上正确居中，但我也有一个 onConfigurationChangeListener 因为我希望某些东西在横向或纵向模式下改变.

override fun onConfigurationChanged(newConfig: Configuration) {
        super.onConfigurationChanged(newConfig)

        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {

            PlayPauseBtn.layoutParams = LinearLayout.LayoutParams(getDps(90), getDps(90))
            ReplayBtn.layoutParams = LinearLayout.LayoutParams(getDps(90), getDps(90))
            ForwardBtn.layoutParams = LinearLayout.LayoutParams(getDps(90), getDps(90))
            FullscreenBtn.setImageResource(R.drawable.ic_fullscreen_exit)
            isfullscreen = true
            ChapterVideoView.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT)
            VideoControls.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
            PlayerLayout.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
            ExtraLayout.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)

        } else {

            PlayPauseBtn.layoutParams = LinearLayout.LayoutParams(getDps(50), getDps(50))
            ReplayBtn.layoutParams = LinearLayout.LayoutParams(getDps(50), getDps(50))
            ForwardBtn.layoutParams = LinearLayout.LayoutParams(getDps(50), getDps(50))
            FullscreenBtn.setImageResource(R.drawable.ic_fullscreen_open)
            isfullscreen = false
            ChapterVideoView.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
            VideoControls.layoutParams = ConstraintLayout.LayoutParams(ChapterVideoView.measuredWidth, ChapterVideoView.measuredHeight)
            PlayerLayout.layoutParams = ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
            ExtraLayout.layoutParams = ConstraintLayout.LayoutParams(ChapterVideoView.measuredWidth, ChapterVideoView.measuredHeight)

        }
    }

这应该从 match_parent 更改为 wrap_content 视频视图的宽度并将其水平居中，但事实并非如此。它实际上全部向左。有什么想法吗？
