/**
* 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:
*
*
* FrameLayout fl = findViewById(android.R.id.custom);
* fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
*
*
* The AlertDialog class takes care of automatically setting
* {@link android.view.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}.
*
*
* Developer Guides
* For more information about creating dialogs, read the
* Dialogs developer guide.
