解决方案

在传递到上下文中的 ProgressDialog 必须是活动,而不是应用

修改

 对话框= ProgressDialog.show(getApplicationContext(),请稍候...,检索GPS数据......,真);

 对话框= ProgressDialog.show(这一点,请稍候...,检索GPS数据......,真);

I'm trying to show a dialog box that says waiting for GPS fix on a map. But it throws BadTokenException. Can some one please correct my code. I not necessarily need a dialog box. It can be a notification on top that 'stays on' and says waiting for gps fix...and disappear once fix is obtained. kindly help me with this!

解决方案

The context you pass to the ProgressDialog must be an Activity, not an Application.

Change

dialog = ProgressDialog.show(getApplicationContext(), "Please wait...","Retrieving GPS data ...", true);

to:

dialog = ProgressDialog.show(this, "Please wait...","Retrieving GPS data ...", true);
