Android 当屏幕旋转时更改工具栏的宽度

我使用屏幕顶部的

工具栏

。当用户旋转设备时，我使用设备传感器来监听旋转，并将

工具栏

旋转到屏幕左侧（我想防止其他视图旋转）。旋转效果很好，但我希望

工具栏的宽度在左侧时为屏幕高度。以下代码未按预期工作：

fun repositionToolBar(){
        val toolBarHeight = toolbar.height
        val screenWidth = rootLayout.width
        val screenHeight = rootLayout.height
        toolbar.rotation = 360f - mCurrentRotation.toFloat()

        if(mCurrentRotation==90){
            toolbar.translationX = -screenWidth/2f+toolBarHeight/2f
            toolbar.translationY = screenHeight/2f-toolBarHeight/2f
            toolbar.layoutParams.width = screenHeight //width of the tool bar changed but toolbar was not in left side, it rotated and laid at center of screen
        }
        else if(mCurrentRotation==270){
            toolbar.translationX = screenWidth/2f-toolBarHeight/2f
            toolbar.translationY = screenHeight/2f-toolBarHeight/2f
            toolbar.layoutParams.width = screenHeight //The toolbar disappeared
        }
        else{ //360 or 0 degree
            toolbar.translationX = 0f
            toolbar.translationY = 0f
            toolbar.layoutParams.width = screenWidth //the toolbar is on top as I expect.
        }
    }

以下是XML文件：

你能指出上面有什么错误吗。谢谢你的关注
