Hello, thank you so much for this great tutorial! I'm wondering, if I want to have a number on the left side (starting with 1 to n) that is increasing with every card that I add, how could I accomplish that?

@CodeVedanam 2 жыл бұрын

Add a text view for the number in card layout and use position to assign text

Great job! but why did you create the AlertDialog dialog object? thx

@CodeVedanam 2 жыл бұрын

We have to show the dialog in on click event of the add button, so if we build the dialog in every on click event, that will be a bad idea right.

Java provides automatic garbage collection. No need to delete a object.
