BACKGROUND
So I have a create and view screen. On the create screen, the user presses the FAB, then a spinner, textview, edittext and checkbox appear. when the user presses the fab again, these set of elements appear again. you can add as many set of elements as you want.
Then when you click to overflow menu and click one of the items in it, it takes you to the 'view' screen, in which all the values and spinners and elements you selected from the create screen, are shown on this view screen.
Additionally, when the user selects values from each spinner, the textview displays a number which is related to that item. Say you pick 'bread' in the spinner, then in the textview it shows '4'. (These are just aisle numbers for shop items btw)
PROBLEM
On the view screen, I am trying to make it so when the user goes on to the view screen, each 'set of elements' are ordered in number order of the textview
So example on the create screen this is what it looks like (number is the viewtext, item is the spinner)
Toast 8 EditText Checkbox
Spread 2 EditText Checkbox
Chocolate 5 EditText Checkbox
Then when the user goes onto the view screen I want it so it's like:
Spread 2 EditText Checkbox
Chocolate 5 EditText Checkbox
Toast 8 EditText Checkbox
If you get what I mean. if further clarification is needed let me know.

I think you are just simply approaching the problem wrongly from the outset.
"Toast","Spread" and "Chocolate" all appear to be forms of a "ingredient" class/object.
Maybe you should look at making a model and viewmodel for the data?
