从asynchTask呼叫runonuithread [英] Call runonuithread from asynchTask

问题描述

我有点难倒一个问题，原谅我，因为我很新的Andr​​oid开发。我做了一些搜索，发现不少不同意见。我有一个调用Web服务并返回一堆JSON结果的AsynchTask。我有（安培;想）异步运行我的web服务。结果集将需要一个RelativeLayout的内内联呈现。我试图做到这一点在我的异步线程而Android不允许从更新的任何UI不是主线程。

I am a bit stumped on a problem and forgive me as I am very new to android development. I did some searching and found quite a few differing opinions. I have an AsynchTask that calls a webservice and returns a bunch of json results. I have to (& want to) run my webservice asynchronously. the result set will need to be rendered inline within a RelativeLayout. I attempted to do this in my asynchronous thread but Android doesn't allow updating the UI from anything that isn't the main thread.

我看到了Runonuithread，但我无法从我的UI线程中调用我的asynchtask。

I see the Runonuithread but I can't call my asynchtask from my ui thread.

什么是异步调用我的web服务，得到的结果，然后将原来的线程上更新mainUI的最佳途径。是否有一个最佳实践架构的角度来看。

What is the best way to call my webservice asynchronously, get the results, and then update the mainUI on the original thread. Is there a best practices from an architecture perspective.

推荐答案

onPostExecute（）是在UI线程上运行，因此尝试使用该方法做你的工作。否则，你可以使用Handler类线程之间进行通信。

onPostExecute() is run on the ui thread, so try using that method to do your work. Otherwise, you can use the Handler class to communicate between threads.
