Question

My app needs to have multiple screen e.g. one login page then another page that displays a list of items and then one that displays details of the the selected item. I want to know what is the general/accepted practice in such cases? I suspect it would be to have multiple layouts but how do I store which item has been selected.

Answer 1

You pass it between the activities, there are various ways to do this. The easiest for simple items is to pass them in the Intent

On Activity A:

...
intent.putExtra("selectedItem", "1");
startActivity(intent);

On Activity B:

Intent intent = getIntent();
String item = intent.getStringExtra("selectedItem");
