假设我有两个不同的api(让api1和api2)。当api1的响应到达时,我调用了同步方法foo1()
。同样,当api2的响应到达时,我调用了另一个同步方法foo2()
。这是情况-我同时调用了两个API。 api1的响应到达,并调用方法foo1()
。同时,来自api2的响应也到达,并且方法foo2()
被调用。
我的问题是执行的顺序是什么? foo2()
会等待foo1()
完成还是会并行执行?

好吧,感谢@DroiDev,我自己尝试了一下。我将Anko library用于异步任务。下面是代码:
doAsync {
Log.d("ASYNC", "Async A started")
foo1()
uiThread {
Log.d("ASYNC", "Async A done")
}
}
Thread.sleep(1000)
doAsync {
Log.d("ASYNC", "Async B started")
foo2()
uiThread {
Log.d("ASYNC", "Async B done")
}
}
}
fun foo1() {
Log.d("ASYNC", "foo1() called")
Thread.sleep(3000)
Log.d("ASYNC", "foo1() done")
}
fun foo2() {
Log.d("ASYNC", "foo2() called")
Log.d("ASYNC", "foo2() done")
}
这是我得到的结果/日志:
07-12 11:44:55.195 23990-24054/gemini.com.jetpack D/ASYNC: Async A started
foo1() called
07-12 11:44:56.195 23990-24028/gemini.com.jetpack D/ASYNC: Async B started
foo2() called
07-12 11:44:56.205 23990-24028/gemini.com.jetpack D/ASYNC: foo2() done
07-12 11:44:56.215 23990-23990/gemini.com.jetpack D/ASYNC: Async B done
07-12 11:44:58.195 23990-24054/gemini.com.jetpack D/ASYNC: foo1() done
07-12 11:44:58.205 23990-23990/gemini.com.jetpack D/ASYNC: Async A done
因此,方法foo2()不会等待foo1()完成。
