推荐答案

LIek已经知道了。你没有足够的技能来解决这个问题。



查看你的代码片段后，将URL放入文本框中是最简单的事情。这个世界要做。问题是你在UI线程上下载文件，阻止文本框自行绘制。



你完全重新设计这个应用程序从头开始使用后台线程做的工作和UI线程，以及维护用户界面，包括您正在下载的URL的屏幕列表。



你现在有这个应用程序写的方式，它注定要失败。

LIek has alreayd been siad. You don''t have the skillset to pull this one off yet.

After look at your code snippet, putt the URL in a textbox would be the easiest thing in the world to do. The problem is that your downloading files on the UI thread, preventing the textbox from drawing itself.

You ened to completely redesign this app from the ground up to use background threads to do the work and the UI thread to, well, maintain the UI, including your on-screen list of URL''s you''re downloading.

The way you have this app written now, it is doomed to failure.
