对,我认为,就这一点而言,你应该认为我是一个完整的菜鸟,我在我的脑海里.

我试图通过几个部分教程来拼凑我对此的理解,每个教程都处理我想要做的不同方面.

它的长短不一,我想要做的就是从URL中读取文本以在文本视图中显示,我的理解是,自3.0更新以来,我需要一个AsyncTask来执行此操作.

任何关于我出错的帮助都会很棒,因为我不明白是什么导致了错误以及如何解决.

我知道doInBackground的try和catch中包含的代码在3.0更新之前就可以自行运行.是否需要修改它以使用Async,但我不知道.

我还想象,一旦这个问题被分类,可能会出现其他问题,如果有人发现一些明显的东西,如果你能指出它我将不胜感激.
