Use a map. Here is a complete project for you as a beginner that does what you want to get started, but you have to read about map and see videos. You can paste this in a project and see how it works for now, very simple to give you an idea:

Sub Globals
    Private btn As Button
    Private edt As EditText
    Private lbl As Label
    Private mp As Map
End Sub

Sub Activity_Create(FirstTime As Boolean)
    mp.Initialize
    mp.Put("house", 50)
    mp.Put("car", 100)
    mp.Put("games", 25)  'then you can store the map into a file and retrieve the map when you want to
  
    edt.Initialize("edt")
    Activity.AddView(edt, 0,0, 200dip, 75dip)
    edt.Hint="Enter object here"
  
    lbl.Initialize("lbl")
    Activity.AddView(lbl,300dip,0,150dip,75dip)  'via code, but you can do it via designer
    lbl.Color=Colors.Blue

    btn.Initialize("btn")
    Activity.AddView(btn,200dip,300dip, 150dip, 100dip)
    btn.Text="Click me"
    btn.Color=Colors.Red
End Sub

Sub btn_Click
    lbl.Text="$" & mp.Get(edt.Text)
End Sub]/code]

Better: A map for every item. Put the maps to a list. This is compatible when you retrieve data from a database (Json)
