时间条问题React-本机-视频

我使用react-native-video和react-native-media-controls来制作视频播放组件。
我能够运行视频,一切都很好。但我想要一个功能,当点击全屏视图,然后相同的视频必须运行在一个模式。
视频甚至在模态上运行。问题是当背景和模态视频都在运行时,视频的时间条表现不正常。时间条在两个不同的时间之间振荡。
我不知道是什么问题。

此问题可能与在组件中使用多个useState挂钩有关。您正在使用多个同名的useState挂钩,这可能会导致混淆并导致意外行为。
例如,您将setIsFullScreen挂接用于两个不同的目的:设置视频播放器的全屏状态并切换模态的可见性。这可能会导致问题,因为这两种状态不一定相关。
一种可能的解决方案是将组件拆分为两个单独的组件:一个用于视频播放器,一个用于模态。这样,你就可以为每个组件使用单独的useState钩子,这将使管理它们的状态变得更容易。
另一个解决方案是为useState钩子使用更具描述性的名称,这样就可以清楚地了解它们的用途。例如,您可以使用setVideoPlayerFullScreensetModalVisible,而不是使用setIsFullScreen来表示视频播放器的全屏状态和模态的可见性。这应该更容易理解每种状态的用途,避免任何混淆。
