推荐答案

在 tabGroupActivity 中，使用progressDialog如下方式(如果你的activity是任何tabhost的子Activity):

In tabGroupActivity ,use progressDialog in the folllowing way( If your activity is the sub Activity of any tabhost):

ProgressDialog.show(getParent(), "Working..", "Downloading Data...",true);

试试这个，还有一件事是使用线程实现ProgressDialog:请参阅此帮助:如何在按钮上获取进度条点击?

try this, and one more thing implement ProgressDialog using threads: see this for help : How to get a progress bar on button click?
