Problem in ArrayAdapter for Custom ListView

I want to show custom list view. I have implemented like : Ch. 4: ListActivity Extended in Android ListView and ListActivity - Tutorial

Is there any way to show list without passing whole String[] name. I want to pass only few names (5 to 6 names) which are on the screen and pass other names dynamically when scrolling the screen ?

Is it must to give a data set to the ArrayAdapter开发者_JAVA百科 ?

Try an OnScrollListener for dynamically add item when scrolling the screen
