Thank you for both of your answers. In the android source, it has:
* If you * want to display a more complex view, look up the FrameLayout called "body" * and add your view to it: * * <pre> * FrameLayout fl = (FrameLayout) findViewById(R.id.body); * fl.add(myView, new LayoutParams(FILL_PARENT, WRAP_CONTENT)); * </pre> How can I hook up to that? Do I need to create a layout xml file with 'body' as it name? And how can I make an AlertDialog loads that layout xml? Thank you.
