What is "android.R.layout.simple_list_item_1"?

Question

Hi everybody,

I started learning android development. I'm following a todolist example from a book. Here is a piece of code:

// Create the array list of to do items
final ArrayList<String> todoItems = new ArrayList<String>();

// Create the array adapter to bind the array to the listView
final ArrayAdapter<String> aa;
aa = new ArrayAdapter<String>(  this, 
                                android.R.layout.simple_list_item_1,
                                todoItems
                            );
myListView.setAdapter(aa);

I can't understand exactly this code especially this line:

android.R.layout.simple_list_item_1

Thank you,

Regards

Zakaria, that is a reference to an built-in XML layout document that is part of the Android OS, rather than one of your own XML layouts.

Here is a further list of layouts that you can use: http://developer.android.com/reference/android/R.layout.html

Also, if you go here: http://www.netmite.com/android/mydroid/frameworks/base/core/res/res/layout/

You can actually view the code for the layouts.
