Alert or Activity?

Question

Java

There is a main activity with a grid of elements. Clicking on an element opens another EditorActivity with a list of other elements. If you click on one of them, a dialog box * for editing the element is shown. It has a pair of EditText, ExpandableListView and a button.
* What would be more correct to use: a dialog box or a new activity? If Alert, then a pile of elements - you have to make it full screen. If activated, then semantically it will show that it is only for editing certain elements. But at the same time, the user will have to call up to 3 activations.
Are there any other advantages to both approaches?

Answer 1

If there is an opportunity not to "produce" extra activity, then you should use it.
