title: how to change text in Android TextView
body: <p>I tried to do this</p>
  
  <pre><code>@Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.main);
  
      t=new TextView(this); 
  
      t=(TextView)findViewById(R.id.TextView01); 
      t.setText("Step One: blast egg");
  
      try {
          Thread.sleep(10000);
      } catch (InterruptedException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
  
      t.setText("Step Two: fry egg");
  </code></pre>
  
  <p>but for some reason, only the second text shows up when I run it.  I think it might have something to do with the <code>Thread.sleep()</code> method blocking. So can someone show me how to implement a timer "asynchronously"?</p>
  
  <p>Thanks.</p>
