立即吐司 [英] Toast Immediately

问题描述

我希望在我的应用下载信息时出现Toast消息，但是即使我将其放在代码之前，也要等到下载完成后才能显示.将我的代码放在一个单独的线程中会引起很多麻烦，但是将吐司放入一个单独的线程中也不起作用.无论如何，在此之前我是否可以收到此Toast消息，或者我只是必须解决头疼的问题?

I would like to have a Toast Message appear while my app is downloading information but even if I put it before my code it doesn't appear until after the download has completed. Putting my code in a separate thread causes many headaches but putting toast in a separate thread doesn't work either. Is there anyway I can have this Toast message come up before this or am I just going to have to work through the headaches?

推荐答案

无论如何，您都应该将异步下载放在单独的线程中，以免禁用主线程的UI.当您调用阻塞的I/O方法时，UI将不会响应.

You should be putting asynchronous downloads in a separate thread anyway, so as to not disable the main thread's UI. When you call a blocking I/O method, the UI will not respond.

在在UI线程中处理昂贵的操作.
