runOnUIThread问题 [英] runOnUIThread question

问题描述

我创建的ListView一个下载管理器，它会显示由进度下载的电流。我想知道我怎么可以更新进度？

I'm create a download manager with listview and it will display the current downloaded by progressbar. May I know how can i update the progressbar?

例如。我有3类。

main.class=是一个列表视图。

"main.class" = is a listview.

mAdapter.class=是扩展ArrayAdapter。

"mAdapter.class" = is extends ArrayAdapter.

mThread.class=实现Runnable开始下载。

"mThread.class" = implements Runnable to start the download.

我有谷歌，发现更新列表视图，或重绘UI应该使用 runOnUIThread 。但我如何能结合在一起的3类？我试着

I have google, and found to update the listview, or redrawing the UI should use runOnUIThread. but how can i combine those 3 class together? I have try

mThread.start(){
   main.runOnUIThread(updated);
}
private updated = new Runnable(){
   mAdapter.progressbar.setProgress(downloaded);
}

这2方法我被放在mThread.class。但它不工作。我可以知道我是我misstake？

this 2 method i was put in "mThread.class". but it doesn't work. May I know what i was my misstake?

P / S：我对我的丑code和糟糕的英语抱歉。希望你们明白我在说什么。谢谢

P/S:I'm sorry about my ugly code and bad english. Hope you guys understand what I'm talking about. Thanks
