Android: Time delay in a loop with updating UI

Question

What I'm trying to create is a simple progress bar, that would load for ~10 sec. So what I want is a for loop like this:

for(int i = 1; i <= 100; i++) {
                    progressDialog.setProgress(i);
                    //100ms delay
                }

Thanks

The following code may be helpful for you.

public void startProgress(View view) {
    // Do something long
    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            for (int i = 0; i <= 10; i++) {
                final int value = i;
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        progressDialog.setProgress(value);
                    }
                });
            }
        }
    };
    new Thread(runnable).start();
}
