How to display a progress bar for 1 minute?

I have a horizontal progress bar in android. I need to make it complete in 60 seconds.

Why doesn't the below code work?

int progress = 0;
progressBarHorizontal.setMax(60);
while(progress < 60) {
     progressHandler.postDelayed((new Runnable() {
        public void run() {                     
           progressBarHorizontal.setProgress(progress);                    
        }                   
     }),progress * 1000);
     progress++;
}

Please suggest some other methods. I tried this:

new Thread(new Runnable() {
                int progress = 0;       
                public void run() {
                    long timerEnd = System.currentTimeMillis() + 60 * 1000;

                    while (timerEnd >  System.currentTimeMillis() ) {

                        progress = (int) (timerEnd - System.currentTimeMillis()) / 1000;
                        // Update the progress bar
                        progressHandler.post(new Runnable() {
                            public void run() {
                                progressBarHorizontal.setProgress(progress);
                            }
                        });                         
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            Log.w("tag","Progress thread cannot sleep");
                        }
                    }
                }
            }).start();

But it is not working either.

The second piece of code actually works, the problem was with my logic.

This one will update the statusbar until it reaches its maximum value:

private int progress = 0;
private final int pBarMax = 60;

...

final ProgressBar pBar = (ProgressBar) findViewById(R.id.progressBar1);     
pBar.setMax(pBarMax);
final Thread pBarThread = new Thread() {
    @Override
    public void run() {
        try {
            while(progress<=pBarMax) {
                pBar.setProgress(progress);
                sleep(1000);
                ++progress; 
            }
        }
        catch(InterruptedException e) {
        }
    }
};

pBarThread.start();

This code works for me

new Thread(new Runnable() {

                public void run() {
                    long timerEnd = System.currentTimeMillis() + 60 * 1000;

                    while (timerEnd >  System.currentTimeMillis()) {

                        progress = 60 - (int) (timerEnd - System.currentTimeMillis()) / 1000;
                        // Update the progress bar

                        progressHandler.post(new Runnable() {
                            public void run() {                     
                                    progressBarHorizontal.setProgress(progress);                    
                            }                   
                        });

                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            Log.w("App","Progress thread cannot sleep");
                        }
                    }
                    progressHandler.post(new Runnable() {
                        public void run() {                     
                                okButton.performClick();                    
                        }                   
                    });
                }
            }).start();

You can try this code for that:

 Thread timer = new Thread(){
public void run(){
    try{
        sleep(10000);
        while(progressBarStatus < 10000){
            StartPoint.this.runOnUIThread(new Runnable(){
                public void run()
                {
                    progressBar.setProgress(progressBarStatus);
                    progressBarStatus += 1000;
                }
            });

        }
    }catch(InterruptedException e){
        e.printStackTrace();
    }finally{

    }
}
};
timer.start();

you can try the CountDownTimer : 

pd = ProgressDialog.show(MovementEntry.this, "", "Please Wait...",
                true, false);
pd.show();
new CountDownTimer(60000, 1000) {
  @Override
  public void onTick(long millisUntilFinished) {
      //this will be done every 1000 milliseconds ( 1 seconds )
      int progress = (60000 - millisUntilFinished) / 1000;
      pd.setProgress(progress);
  }

   @Override
   public void onFinish() {
      //the progressBar will be invisible after 60 000 miliseconds ( 1 minute)
      pd.dismiss();
   }

}.start();
