Kotlin：从 Fragment 调用时 FragmentManager 显示错误 [使用适配器]

Question

适配器类：

class TeamsAdapter(
supportFragmentManager: FragmentManager,
teams_list: MutableList<Team>,
match_id: String
) : FragmentPagerAdapter(supportFragmentManager) {code}

片段类：

lateinit var teamsAdapter: TeamsAdapter

teamsAdapter = TeamsAdapter(supportFragmentManager, match?.teams!!, matchId)

错误：Unresolved reference: supportFragmentManager

但是，当在 Activity 而不是 Fragment 类中时，整个代码可以正常工作。

Answer 1

如果您使用片段然后使用上下文进行转换，可以通过转换活动来解决

  fragmentManager = (activity as FragmentActivity).supportFragmentManager
