Menu
after creating some menus with simple_list_item_1 (which worked very fine) I tried to replace this by simple_list_item_2, but my system throws around with exceptions...
Now I'm wondering how to create such a two-different-sized-line-entry for my list...is there any trap for beginners? Can someone please help me fixing my (small!?) problem?
My code looks like this:
ListAdapter listAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_2, fileNames);
setListAdapter(listAdapter);
My String[] fileNames stores all strings to display in ascending order (does this matter for the functionality?!)
After unsuccessfully searching in some forums I now hope that someone of you can give me an useful suggestion.
nice greetings, poeschlorn

R. id. text1 is an used for TextView views. You can find it in many layouts from the framework ( select_dialog_item , select_dialog_singlechoice , simple_dropdown_item_1line , etc.).
What is the purpose of using setContentView R layout Activity_main )? layout. activity_main ); This is a Java method called setContentView. It sets the XML file you want as your main layout when the app starts.
android.R.layout.simple_list_item_1 , this is row layout file in your res/layout folder which contains the corresponding design for your row in listview .
simple_spinner_item is the layout of each drop-down item on the spinner list.
simple_list_item_2 is different, instead of just a TextView it contains a TwoLineListItem containing two TextViews. ArrayAdapter is not going to work here, because the constructor you're using expects only a TextView; just look at the constructors. Instead you'll either have to create a custom adapter or use one that supports it like SimpleCursorAdapter or (I think) SimpleAdapter. This guy has a somewhat hacky solution that might work for you.
