A progress bar is a visual indicator of progress in some operation. Normally, we find linear horizontal line representing the progress bar. but,we can also have circular progress bar to show progress of specific task. There are many ways to do so, I have shown one of them.
Have a look on few code snippets,

public void callAsynchronousTask() {
final Handler handler = new Handler();
Timer timer = new Timer();
TimerTask doAsynchronousTask = new TimerTask() {
@Override
public void run() {
handler.post(new Runnable() {
public void run() {
try {
progressBar.incrementProgressBy(1);
int stringProgress=progressBar.getProgress();
progressText.setText(stringProgress+"");
} catch (Exception e) {
}
}
});
}
};
timer.schedule(doAsynchronousTask, 0, 10);
