Progress bar onclick event

Question

Is it possible in android to get onclick event on the progress bar which will give on the percentage(or something like that) with reference to progress bar. Say at point A it gives 2.3% and point X it gives 46.7% something like that. Hope the question is clear.

Any other help/approach to this solution will also be appreciable.

See this Progress bar Example

public class MyAndroidAppActivity extends Activity {

Button btnStartProgress;
ProgressDialog progressBar;
private int progressBarStatus = 0;
private Handler progressBarHandler = new Handler();

private long fileSize = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    addListenerOnButton();

}

public void addListenerOnButton() {

    btnStartProgress = (Button) findViewById(R.id.btnStartProgress);
    btnStartProgress.setOnClickListener(
             new OnClickListener() {

       @Override
       public void onClick(View v) {

        // prepare for a progress bar dialog
        progressBar = new ProgressDialog(v.getContext());
        progressBar.setCancelable(true);
        progressBar.setMessage("In Progress ...");
        progressBar.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressBar.setProgress(0);
        progressBar.setMax(100);
        progressBar.show();

        //reset progress bar status
        progressBarStatus = 0;

        //reset filesize
        fileSize = 0;

        new Thread(new Runnable() {
          public void run() {
            while (progressBarStatus < 100) {

              // process some tasks
              progressBarStatus = doSomeTasks();

              // your computer is too fast, sleep 1 second
              try {
                Thread.sleep(1000);
              } catch (InterruptedException e) {
                e.printStackTrace();
              }

              // Update the progress bar
              progressBarHandler.post(new Runnable() {
                public void run() {
                  progressBar.setProgress(progressBarStatus);
                }
              });
            }

            // ok, file is downloaded,
            if (progressBarStatus >= 100) {

                // sleep 2 seconds, so that you can see the 100%
                try {
                    Thread.sleep(2000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                // close the progress bar dialog
                progressBar.dismiss();
            }
          }
           }).start();

           }

            });

    }

// file download simulator... a really simple
public int doSomeTasks() {

    while (fileSize <= 1000000) {

        fileSize++;

        if (fileSize == 100000) {
            return 10;
        } else if (fileSize == 200000) {
            return 20;
        } else if (fileSize == 300000) {
            return 30;
        }
        // ...add your own

    }

    return 100;
  }
}
