android progressDialog is static

I have an issue with my ProgressDialog object.开发者_运维知识库 When I show it first time, it is spinning, but after I dismiss it and show it again, the dialog is static, it it not spinning... Can you please tell me why? All of this happens in the UI thread. Thanks

are you doing any processing in the UI thread during the second show of the ProgressDialog? If so, you need to move the processing to a background thread. Otherwise, the progress dialog does not get the CPU to update(spin) itself.
