我应该在Android AsyncTask中调用super.onPostExecute(result)吗? [英] Should I call super.onPostExecute(result) in Android AsyncTask?

问题描述

我想知道在Android AsyncTask中调用super.onPostExecute(result)或super.onPreExecute有什么意义吗?我一直在打电话给他们，甚至在关于AsyncTask的Android文档中( Android API参考:AsyncTask )，将其省略.那么我是否打电话给他们有意义吗?

I wonder if it has any meaning to call super.onPostExecute(result) or super.onPreExecute in Android AsyncTask? I have been always calling them, but even in Android documentation about AsyncTask (Android API Reference: AsyncTask) they are omitted. So does it make any sense if I call them or not?

推荐答案

不，不需要调用超类.如果查看 AsyncTask 源，您将看到超类什么也不做:

No, there is no need to call the superclass. If you take a look at the AsyncTask source, you will see that the super class does nothing:

@SuppressWarnings({"UnusedDeclaration"})
protected void onPostExecute(Result result) {
}
