TextView.setText(SOME_TEXT_HERE) what is difficult about that?

[Master Mascus]

I did add these 2 line of codes on line 71. But it does not display the text..

TextView txt_news = (TextView)findViewById(R.id.Sportnews);
txt_news.append(entryText);

the problem that seems to me is that the function parseXML is called from the background thread. In order to be able to update the gui, you must do it in the main thread, or also known as the UI thread as far as i know. You should update the textview in the onPostExecute function. This function works in the main thread.
