Hello, my problem is how to save different strings that are written in an Editview.

I can save a variable every time a button is pressed. But I don’t know how to save another string in another variable, someone can help me?

(Another question would be how to create variables in an automatic way without declaring before)

To store multiple variables, you need a structure to add multiple variables.

If you know how many entries you will have you can use an Array:

String[] valores = new String[5] // 5 = o número de "gavetas" que seu Array terá

This way you can access the content by doing valores[índice]

When you don’t know how many entries you will have, you can use a Object List.

List<String> minhaLista = new ArrayList<>();

This way, when you need to store a variable, use minhaLista.add("Minha String"); and to recover the value use minhaLista.get(índice)
