问题描述
基本上，此刻我展示（ loading.setVisibility（View.VISIBLE）; ）加载屏幕，然后加载使用的BufferedReader一些外部数据，然后隐藏加载屏幕（ loading.setVisibility（View.INVISIBLE）; ）之后。问题是在载入画面永远不会显示。在code是所有在正确的地方GUI只是因为载入画面再次被设置为不可见并没有等到什么时候这显然是太晚了该方法的最终更新。
Basically at the moment I'm showing a loading screen (loading.setVisibility(View.VISIBLE);) then loading some external data using a "BufferedReader" and then hiding the loading screen (loading.setVisibility(View.INVISIBLE);) afterwards. The problem is the loading screen is never shown. The code is all in the correct place the GUI just doesn't update until the end of the method when it is obviously too late because the loading screen is set to invisible again.
有没有办法强制更新通过方法UI中旬的方式？
Is there any way to force update the UI mid way through a method?
任何帮助将是非常美联社preciated！
Any help would be much appreciated!
推荐答案
不使用后台线程你不能做到这一点。有许多方法可以做到这一点在Android，但最简单的就是使用
You can't do this without using a background thread. There are a number of ways you can do this on Android, but the simplest is to use AsyncTask
这是值得一读了解更多这方面的信息。
It's worth reading Painless threading for more information on this.
