 public class MainActivity extends Activity { // URL Address String url = "http://www.androidbegin.com"; ProgressDialog mProgressDialog; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Locate the Buttons in activity_main.xml Button titlebutton = (Button) findViewById(R.id.titlebutton); // Capture button click titlebutton.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { // Execute Title AsyncTask new Title().execute(); } }); } // Title AsyncTask private class Title extends AsyncTask<Void, Void, Void> { String title; @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected Void doInBackground(Void... params) { try { // Connect to the web site Document document = Jsoup.connect(url).get(); // Get the html document title title = document.title(); } catch (IOException e) { e.printStackTrace(); } return null; } @Override protected void onPostExecute(Void result) { // Set title into TextView TextView txttitle = (TextView) findViewById(R.id.titletxt); txttitle.setText(title); mProgressDialog.dismiss(); } } }

将以下代码直接放在setContentView...行下

new Title().execute();
