问题 When the user clicks on the save button, an AlertDialog appears and asks the user to input text for the file name. If the user clicks the positive button ("Ok") without specifying a name, I want to display a toast which asks them to do so, and keep the AlertDialog open.

问题 I need to create an AlertDialog with multiple choice items but I'm having some trouble trying to set a custom layout file to the internal ListView. For single choice items I use a constructor that takes a ListAdapter as parameter and this way I can set the proper layout resource for each row: builder.setSingleChoiceItems(new ArrayAdapter<String>(getActivity(), R.layout.list_item_single_choice_answer, items), checkedItem, new DialogInterface.OnClickListener() { @Override public void onClick

问题 I have a theme that has a Theme.AppCompat.Dialog parent.
