+ * 根据视频的尺寸与容器尺寸比例，动态调整 [VideoView] 的尺寸以适应视频的尺寸
+ * 解决 [VideoView] 尺寸比例与视频尺寸比例不一致导致视频拉伸的问题
+ *
+ * 容器可以是屏幕或者 [VideoView]
+ *
+ * 使用方式：
+ * 1. 通过 [VideoView.setOnPreparedListener] 向 [VideoView] 设置 [MediaPlayer.OnPreparedListener] 监听
+ * 2. 通过 [MediaPlayer.OnPreparedListener] 回调获取到视频的真实宽高，调用该方法传入参数进行适配
+ * 3. 如果需要考虑横竖屏切换，请在横竖屏改变监听回调中再次调用该方法进行适配
+ *
+ * @receiver [VideoView]
+ * @param containerW Float 容器的真实宽
+ * @param containerH Float 容器的真实高
+ * @param videoW Float 视频的真实宽
+ * @param videoH Float 视频的真实高
