如何避免ANR对话框应用程序未响应 [英] How to avoid the ANR dialog Application Not Responding

问题描述

我正在开发一款Android应用，该应用使用在线服务，我需要加载我的Fragments。基本上，我有一个菜单，每个按钮替换下面的碎片。当我点击一个按钮时，片段开始被替换，如果我同时按下了键盘上的另一个按钮，我得到应用程序不响应对话框，然后单击等待，并成功加载我的片段。有没有办法阻止这种情况发生？由于Web服务，我的应用程序总是需要几秒钟才能加载。我在Google上读到，我可以使用AsyncTask，并在DoOnBackground方法上完成加载。我不知道这是否有效，但我甚至无法尝试，因为它不会让我改变视图，它会抛出一个关于只有原始线程可以改变视图的错误..我需要该服务完成加载我的视图，所以我甚至不能使用AsyncTask做这个服务..我现在已经没有想法了！有一种方法可以做到这一点..我欣赏建议！

I'm working on an Android app, which uses an online service, which i need to load my Fragments. Basically, i have like a menu, and each button replaces a Fragment underneath. When I click a button, the fragment starts being replaced, and if I press another button from my keyboard on the meantime, i get the Application Not Responding dialog, and then i click Wait, and my Fragment loads successfully. Is there a way to prevent that from happening? My app will always take a few seconds to load, because of the web service. I read on Google, that i could use AsyncTask, and finish the loading on the DoOnBackground method.. I don't know if that works, but I can't even try, because it won't let me change the view there, it throws an error about only the original thread can change the views.. and I need the service to finish loading my view, so i can't even do the service with the AsyncTask.. I'm running out of ideas now! there has to be a way to do this.. I appreciate suggestions!

推荐答案

防止这种情况发生的方法？

是的：不要在主应用程序线程上花太长时间。使用 StrictMode 来识别可能的罪魁祸首（磁盘I / O，网络I / O），并使用Traceview找出你正在做的事情，可能需要很长时间。 / b>

Yes: don't take so long on the main application thread. Use StrictMode to identify likely culprits (disk I/O, network I/O), and use Traceview to find out what else you are doing that might be taking too long.

My app will always take a few seconds to load, because of the web service.

由于Web服务的原因，我的应用总是需要几秒钟才能加载。

这应该在后台线程中完成。

That should be done in a background thread.

我在Google上阅读过，使用AsyncTask，并在DoOnBackground方法上完成加载。我不知道这是否有效，但我甚至不能尝试，因为它不会让我改变视图，它会抛出一个关于原始线程可以改变视图

I read on Google, that i could use AsyncTask, and finish the loading on the DoOnBackground method.. I don't know if that works, but I can't even try, because it won't let me change the view there, it throws an error about only the original thread can change the views

这就是为什么你要更新 onPostExecute（）方法，如 AsyncTask 。

Which is why you update the views from the onPostExecute() method, as is described in the documentation for AsyncTask.
