    copied!<p>I'm having some problems displaying a ProgressDialog. I have a method that scrapes information from a website, and I want to show the user some kind of "Loading" window instead of the app just looking like it is hanging for a second or two when it is working.</p> <p>Everything works fine when I don't implement a ProgressDialog &amp; Thread, but as soon as I try to implement a Thread to do the heavy lifting, the AboutMe View window is empty.</p> <p>I have a MainActivity with a TextView that registers a OnClickListener.</p> <p>A Click on the TextView does a:</p> <pre><code> startActivity(new Intent(getBaseContext(), AboutMe.class)); </code></pre> <p>This is most of the AboutMe.class Activity:</p> <pre><code>public class AboutMe extends Activity { private ProgressDialog aboutMeProgressDialog; private String htmlAboutMe = ""; @Override protected void onCreate(Bundle savedInstanceState) { getAboutMe(); // Get information from Internet super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFeatureDrawableResource(Window.FEATURE_NO_TITLE, android.R.drawable.ic_dialog_alert); setContentView(R.layout.abutme); TextView tvAbout = (TextView) findViewById(R.id.aboutMe); tvAbout.setText(Html.fromHtml(htmlAboutMe)); } private void getAboutMe() { try { aboutMeProgressDialog = ProgressDialog.show(AboutMe.this, "", "Loading"); new Thread() { @Override public void run() { try { /** Code to scape webpage **/ } catch (Exception exp) { exp.printStackTrace(); } handler.sendEmptyMessage(0); } }.start(); } catch (Exception ex) { ex.printStackTrace(); } } private final Handler handler = new Handler() { @Override public void handleMessage(final Message msg) { aboutMeProgressDialog.dismiss(); } }; </code></pre> <p>I'm clearly missing out on something trivial, but I've tried to Google just about everything I can think of, but still can't get a Thread together with ProgressDialog to work for me.</p>
