public class ProgressActivity extends Activity{

    private ProgressBar mBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mBar = (ProgressBar) findViewById(R.id.progress_horizontal);

        init();
    }

    private void init() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    int max = mBar.getMax();
                    while(mBar.getProgress() != max){
                        int progressStep = max / 10;
                        int curProgress = mBar.getProgress();
                        mBar.setProgress(curProgress + progressStep++);
                        Thread.sleep(10*1000);
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
