Refreshing Marquee Text on Android

Question

On launch, my marquee text is working normally. Then i want to update text in somewhen. I get text on internet and set it to textview:

marqueeText.setText(Html.fromHtml(GetNew.getNews()));

There is no problem about getting text from internet. But then the text is not sliding. What is the problem about that? Thanks for your help.

Edit: I get this log when try to refresh it. I refresh it in a thread.

You should use the handler for working on UI thread.

private Handler handler = new Handler(new Callback() {

        public boolean handleMessage(Message msg) {
            marqueeText.setText(Html.fromHtml(GetNew.getNews()));
            marqueeText.setSelected(true);
            marqueeText.setEllipsize(TruncateAt.MARQUEE);
            return false;
        }
    });

And when you want to update the text in thread then use handler.sendEmptyMessage(0);
