我尝试运行两个异步作业。

有一个按钮，单击后会取消其中一项作业。但我注意到当我这样做时，其他工作也会被取消。

发生了什么？

class SplashFragment : BaseFragment(R.layout.fragment_splash), CoroutineScope by MainScope() {

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    launch {
        val countdown = async { countDown() }
        val ipAndMaintain = async { checkIPAndMaintain() }

        btnSkip.onClick {
            countdown.cancel() // cancel countdown
            btnSkip.isVisible = false
            if (!ipAndMaintain.isCompleted) {
                showLoadingDialog()
            }
        }
        countdown.await()
        startOtherPage(ipAndMaintain.await())
    }
}

private suspend fun countDown() {
    var time = 3
    while (time >= 0) {
        btnSkip.text = getString(R.string.skip, time)
        delay(1000)
        yield()
        time--
    }
}

private suspend …
