title: How to show a Progress dialog while waiting for a thread to finish?
body: <p>Here is the code im trying to call inside <code>onCreate()</code></p>
  
  <pre><code>        _t = new TheThread(this);
          pd = new ProgressDialog(this);
          pd.setMessage("Trip Detection ..");
          pd.show();
          _t.start();
          while(_t.isAlive()){
              //DO NOTHING..WIAITING TILL MAIN THREAD FISHIN
          }
          printToScreen();
          pd.dismiss();          
  </code></pre>
  
  <p>printToScreen() updates a list view. The content of the list view is updated using the tread _t. But when i call this method i dont see any of the "waiting" message coming up. Phone freezes as it used to be before (when i was not running content on a thread). Any suggestions ?</p>
