如何用cameraX在画布上绘制动画，达到理想的fps效果？

    def camerax_version = "1.1.0-alpha10"

val cameraProviderFuture = ProcessCameraProvider.getInstance(this)
cameraProviderFuture.addListener(Runnable {
    val cameraProvider = cameraProviderFuture.get()

    // 设置预览用例
    val preview = Preview.Builder()
        .build()
        .also {
            it.setSurfaceProvider(previewView.createSurfaceProvider())
        }

    // 绑定预览用例

        isAntiAlias = true
    }

    override fun onDraw(canvas: Canvas) {
        super.onDraw(canvas)

        // 在画布上绘制动画
        canvas.drawCircle(/* 绘制圆的位置和属性 */)

        // 刷新界面，实现动画效果
        invalidate()
    }
}

private val handler = Handler(Looper.getMainLooper())

private val frameRate = 60 // 设置帧率为60fps
private val frameDuration = 1000L / frameRate // 计算每帧的刷新间隔

private val frameRunnable = object : Runnable {
    override fun run() {
        // 刷新界面
        invalidate()

        // 延迟一定时间后再次调用该Runnable，实现循环刷新
        handler.postDelayed(this, frameDuration)
    }
}

// 在View的onAttachedToWindow方法中启动动画刷新
override fun onAttachedToWindow() {
    super.onAttachedToWindow()
    handler.post(frameRunnable)
}

// 在View的onDetachedFromWindow方法中停止动画刷新
override fun onDetachedFromWindow() {
    super.onDetachedFromWindow()
    handler.removeCallbacks(frameRunnable)
}
