Asynctask get percentage of the progress in java

Question

I have a AsyncTask that is unzipping files. Is it possible to get the percentage of the progress of the AsyncTask to show it in a horizontal ProgressBar ?

Answer 1

Override onProgressUpdate in your AsyncTask . Then call publishProgress from within the background thread. onProgressUpdate will be invoked on the UI thread with the parameter from publishProgress .

You determine the type of the progress parameter with the second type argument in AsyncTask .

Answer 2

AsyncTask has method onProgressUpdate(Integer...) that you can call each iteration for example or each time a progress is done during doInBackground() by calling publishProgress().
