我可以创建主线程（UI线程）之外的用户界面？ [英] Can I create UI outside main thread (UI Thread)?

问题描述

我的UI是很好的理由（计算数以百计的看法测量）pretty长生成（约20秒）。
我（觉得呢？）在主线程创建它们，然后我运行一个progressdialog使用户等待。
虽然，主线程已经被创建其他计算的过载。
我能那么主线程之外创建UI虽然我得到几个观点测量？

my UI is pretty long to generate (about 20 seconds) for good reasons (calculating measurements of hundreds of views). I (think?) have to create them in the main thread, and then I run a progressdialog to make the user wait. Though, the main thread is already overloaded by the creation of the other calculations. Could I then create UI outside the main thread though I have to get measurements of several views?

推荐答案

虽然有些人说，他们已经得到它的工作，无论是的 Dianne和罗曼说的，你不应该这样做了讨论，整个UI树是单线程的。他们说，这是不能保证的工作，应尽量避免。

While some people say that they have got it to work, both Dianne and Romain say that you should not do this in a discussion, as the entire UI tree is single threaded. They say that it is not guaranteed to work, and should be avoided.

我不能想出中，你会需要几百个实例，并在同一时间绘制视图中的任何场景。也许你需要使用一个ListView，或者实现某种延迟加载在你的应用程序。

I can't come up with any scenario in which you'd need hundreds of Views instantiated and drawn at the same time. Perhaps you need to use a ListView, or implement some kind of lazy loading in your app.
