问题
I want to use the Progress Dailog in my application. I am facing one issue in doing it, after some RnD I came to know that it is not quite possible to create the progress Dialog I have the Activity Group Class for the TabHost in the application.
I have exactly the same scenario, I have the TabHost in my application and an ActivityGroup Class that has the TabHost Classes. So, when I try to create the Progress Dialog for the Class that is in the Activity Group Class I cannot create it. But if I try to create the Progress Dialog for the Class that is not in the Activity Group I can create it with no issues.
Is there any solutions now?
回答1:
I think the problem is with context of the progress dialog
Try giving the context of the dialog as getParent()
ProgressDialog.show(getParent(), " Loading...", "Please wait...", true, false);
