SetText Impossible because bad thread

Question

I'm beginning with android apps and I got a little problem. My app takes a part of a HTML Page and puts some text of this HTML in Textviews. The error is: "Only the original thread that created a view hierarchy can touch its views". If I undestood, it means I should put the "setText()" in the onCreate() function but it doesn't work neither because the HTML isn't completely loaded.

Sorry for my poor english and thank's if you have an answer.

您应该使用事件使视图线程更新视图：）再看一下文档。
