Android Display Progress Dialog while doing a background task

Question

I am building an android app which will download some data and display it to the user. Now I need to show a circular progress bar until the data is downloaded. The download will begin on a button click. How can I achieve this? Sample code would be very helpful.

Yes you can do that with Progressbar widget. And thread in your class. — MysticMagicϡ, Nov 14 '12 at 08:08

You need to use an AsyncTask to execute your download and ProgressBar instance to show a circular progress.

There are many resources you can find which describe exactly how to use the combination to do what you want.

Check Android AsyncTask class for what you want to achieve.

Basically you start showing a ProgressDialog in the onPreExecute of AsyncTask and dismiss it in onPostExecute when your background job is done.

Check these also.
