title: Set 2 different text colors in alertdialog
body: <p>I am trying to set 2 different colors for the text in a alertdialog, through spannable but unfortunatly all the text stays white.
  The String <strong>'message'</strong> <strong>should be green</strong> and the String <strong>'message2' normal white</strong>.</p>
  
  <p>If I <strong>remove</strong> the second String <strong>message2</strong> in below line, everything is as it should be.</p>
  
  <pre><code>.setMessage(ssBuilder + message2)
  </code></pre>
  
  <p>Code for the dialog:</p>
  
  <pre><code>public static AlertDialog createDarkDialog(Context context, String title, String message, String message2) {
          ContextThemeWrapper ctw = new ContextThemeWrapper(context, R.style.DarkAlert);
  
          SpannableStringBuilder ssBuilder = new SpannableStringBuilder(message);
          RelativeSizeSpan largeSizeText = new RelativeSizeSpan(1.0f);
          ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(Color.GREEN);
          ssBuilder.setSpan(largeSizeText, 0, message.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
          ssBuilder.setSpan(foregroundColorSpan, 0, message.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
  
          AlertDialog ad = new AlertDialog.Builder(ctw)
                  .setTitle(title)
                  .setMessage(ssBuilder + message2)
  
                  .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {
                          // Do something
                          dialog.dismiss();
                      }
                  })
                  .setNegativeButton("No", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {
                          dialog.dismiss();
                      }
                  })
                  .setCancelable(false)
                  .create();
          return ad;
      }
  </code></pre>
  
  <p>How I call the dialog:</p>
  
  <pre><code>Utils.createDarkDialog(mContext, "Title:", "This should be green" + "\n\n", "and this should be white.").show();
  </code></pre>
