title: Invalidate is not redrawing the screen. Android
body: <pre><code>BufferedReader hl  = new BufferedReader(new InputStreamReader(getResources().openRawResource(R.raw.lines)));
                  while(hl.ready()){
                      showLines.append(hl.readLine()+"\n");
                      showLines.invalidate();
                      Thread.sleep(10);
                  }
  </code></pre>
  
  <p>That is my code but it is not redrawing when I tell it to.  It is supposed to redraw after every line that is added to textview, but it still only redraws at the end?  Can someone please help me, I can't figure it out.</p>
