@Fengweiyuu oh i got it, you should correct part of your code to:

 renderScene={({ route: sceneRoute }) => {
    switch (sceneRoute.key) {
      case 'all':
        return (
          <ArticleRouteScene tabIndex={0} type="1" columnCode={columnCode} />
        )
      case 'video':
        return (
          <ArticleRouteScene tabIndex={1} type="2" columnCode={columnCode} />
        )
      case 'article':
        return (
          <ArticleRouteScene tabIndex={2} type="3" columnCode={columnCode} />
        )
      default:
        return null
    }
  }}
