我有一个实验协同程序函数，如下
runBlocking {
Log.d("Track", "Launching...")
val job = launch(Dispatchers.IO) {
repeat(2000) {
repeat(2000) {
Log.d("Track", "Suspending...")
}
}
Log.d("Track", "Done...")
}
Log.d("Track", "Launched...")
delay(100)
Log.d("Track", "Canceling...")
job.cancel()
Log.d("Track", "Canceled...")
}
当我运行它时，即使在取消之后，协同程序也会继续作为下面的日志运行
Track: Launching...
Track: Launched...
Track: Suspending...
Track: Suspending...
Track: Canceling...
Track: Suspending...
Track: Suspending...
Track: Canceled...
Track: Suspending...
Track: Suspending...
Track: Suspending...
Track: Suspending...
:
: (a lot more suspending)
:
Track: Done...
为什么我不能取消我的郊游？我应该放一个yield()只是为了不时地检查一下，以防取消它吗？
显然，正如Kotlin文档中所提到的，取消是合作的。我们需要yield()或检查isActive
