I am new as new, but from what I got:
"this" is context. It is "this" in all examples I saw. What is in
parenthesis you will see if you highlight createFromResource in
eclipse. R.array.planets is a string array. It can be created like:
final String[] branches= new String[] {
"Brno", "Černý Most", "Zličín"
};
and then placed in: ...ArrayAdapter.createFromResource(this,
branches, ...
Last is layout, which you are calling, this one is generic from
google. You can create your own in res/layout folder and summon there:
..R.layout.row);
(in case file is named row.xml).
Nice tutorial about layouts is http://commonsware.com/Android/excerpt.pdf
