/**
 * A subclass of Dialog that can display one, two or three buttons. If you only want to
 * display a String in this dialog box, use the setMessage() method.  If you
 * want to display a more complex view, look up the FrameLayout called "custom"
 * and add your view to it:
 *
 * <pre>
 * FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
 * fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
 * </pre>
 * 
 * <p>The AlertDialog class takes care of automatically setting
 * {@link WindowManager.LayoutParams#FLAG_ALT_FOCUSABLE_IM
 * WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM} for you based on whether
 * any views in the dialog return true from {@link View#onCheckIsTextEditor()
 * View.onCheckIsTextEditor()}.  Generally you want this set for a Dialog
 * without text editors, so that it will be placed on top of the current
 * input method UI.  You can modify this behavior by forcing the flag to your
 * desired mode after calling {@link #onCreate}.
 *
 * <div class="special reference">
 * <h3>Developer Guides</h3>
