[android-developers] Re: How I can add an int to an array if the user clicks a button?

OK thanks for the very fast reply.

So If I use

ArrayList<int> array;

array = new ArrayList(20);

button.setOnClickListener(new View.OnClickOnListener) {

@Override
public void onClick (View v) {
//something to add the button's specified number to the
array

}
}

And I use the add method for add a number to the ArrayList will be
good? And here is the question, that How I can compare them, too?

Thanks
