How to refresh text in a TextView programatically?
<p>I have following timer:</p>

<pre><code>Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {

    @Override
    public void run() {
        --mTimer;
        mTimeLeft.setText(String.valueOf(mTimer));
    }

}, 0, 1000);
</code></pre>

<p>Text in the <code>TextView</code> will change when I touch the screen.</p>

<p>How can I refresh the <code>TextView</code> programatically? </p>
