title: forceLayout(), requestLayout()
body: <p>My reading of the android documentation finds the methods forceLayout() (which is to produce a layout display at the next layout request) and requestLayout() (which is supposed to post an immediate layout request), but I can not get them to behave as advertised. In particular, if I do one set text before  a Thread.Sleep and one after, it waits for the Sleep to finish before setting both texts at once, whether or I call the forceLayout() and requestLayout() in between.  Please do not respond with a lot of nonsense about how I should not call a Thread.Sleep in the UI thread.  If I wrap the Thread.Sleep in a CountDownTimer it works perfectly well (as long as I have the tick time short enough to not interfere with sleep time, and the duration of the timer long enough to permit the Sleep to finish.  The following is an example:</p>
  
  <pre><code>    int i=0;
  TextView tv2;
  TextView tv1;
  LinearLayout ll;
  Button bt;
  @Override
      public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      ll=new LinearLayout(this);
      ll.setOrientation(LinearLayout.VERTICAL);
      tv1=new TextView(this);
      tv2=new TextView(this);
      bt=new Button(this);
      bt.setText("Press to start");
      ll.addView(bt);
      ll.addView(tv1);
      ll.addView(tv2);
      tv2.setText("");
      setContentView(ll);
      bt.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {
              tv1.setText("starting sleep");
              new CountDownTimer(6000,50){
                public void onTick(long msuf)
                  {if(i==1)
                      {
                  try{
                Thread.sleep(4000);
                tv2.setText("waking up");
                 }
              catch(InterruptedException e){};
              }
                  i++;
                   }
                 public void onFinish(){}}.start();
                }         
        });
  
          }
