title: AlertDialog with urls and text
body: <p>I am trying to show in an android AlertDialog some text and some words to be clickable opening a web page. I am doing something wrong with it cause it does not open the link i am telling him and the hole text is clickable, which i am trying to avoid....
  This is my code:</p>
  
  <pre><code>final SpannableString s = new SpannableString(
                          Html.fromHtml("&lt;br&gt;&lt;a href=\"http://google.com\"&gt;a new link&lt;/a&gt;")
                          );
  
          final TextView tx1 = new TextView(this);
          tx1.setText(getString(R.string.librarytextpart1) 
                  + s
                  + getString(R.string.librarytextpart2));
          tx1.setAutoLinkMask(RESULT_OK);
          tx1.setMovementMethod(LinkMovementMethod.getInstance());
  
          Linkify.addLinks(s, Linkify.ALL);
          AlertDialog.Builder builder = new AlertDialog.Builder(this);
          builder.setTitle(getString(R.string.library))
                  .setCancelable(false)
                  .setPositiveButton("OK",
                          new DialogInterface.OnClickListener() {
                              public void onClick(DialogInterface dialog,
                                      int id) {
                              }
                          })
  
                  .setView(tx1).show();
  </code></pre>
  
  <p>When clicked on the SpannableString text in dialog, it shows the entire text is clickable ... and still does not open a webpage. For sure I don't understand something right from the documentation, but don't see what. Can you help, please?</p>
