Dynamic size of an array of java objects?

Question

Java

android.leocardz.com/multiple-layout-listview
Made according to the lesson, everything is fine.
But how to define a dynamic array? I don't know beforehand how many elements there will be.
Tried it in different ways, but I'm still a noob in Java.
PS Yes, I know that RecyclerView is better, but ListView is also suitable for my purposes.
My goal is simple: to display data from the table in a more or less beautiful form. I write for myself. Along the way, getting acquainted with ANDROID DEVELOPMENT.

Answer 1

Solution (if anyone needs it):

//Создаю:
List<List<String>> list = new ArrayList<>();
//Добавляю в цикле так:
list.add(new ArrayList());
list.get(list.size()-1).add(text);
list.get(list.size()-1).add(text2+"");

//Затем(после работы цикла) заполняю:
final ListViewItem[] items = new ListViewItem[list.size()];
li=0;
for (List item : list) {
items[li] = new ListViewItem(item.get(0),Integer.parseInt(item.get(1)));
li++;
}

Not the best, but simple and working.

Answer 2

Dude, use collections. I think ArrayList can suit you well for this task. And also, learn Java well, then it will be easier to breathe in Android development.
