copied!<p>Just for some inspiration, here is the general code format that I have used successfully to show a horizontal progress bar which updates while a background task is running. I know it doesn't answer your exact question, but I hope it helps you to find your solution. </p> <pre><code>ProgressDialog myProgressDialog; private void someFunctionThatStartsTheAsyncTask() { new myBackgroundTask.execute(someIntegerArgument); } private class myBackgroundTask extends AsyncTask<Integer, Integer, Boolean> { protected void onPreExecute() { myProgressDialog = new ProgressDialog(myContext); myProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); myProgressDialog.setTitle("Doing something in background..."); myProgressDialog.setMessage("Please wait..."); myProgressDialog.setCancelable(false); myProgressDialog.setIndeterminate(false); myProgressDialog.setMax(100); myProgressDialog.setProgress(0); myProgressDialog.show(); } protected Boolean doInBackground(Integer... params) { int someVariable = params[0]; boolean success; for (whatever loop conditions) { // some long-running stuff, setting 'success' at some point ... publishProgress(newPositionForProgressBar); } return success; } protected void onProgressUpdate(Integer... progressPosition) { myProgressDialog.setProgress(progressPosition[0]); } protected void onPostExecute(Boolean result) { myProgressDialog.dismiss(); if (result) { //doInBackground returned true } else { //doInBackground returned false } } } </code></pre>
