i not used this table view but here you can get the data from key value pairs.
Job.GetString is the JSON Data
it used the JSON Library 1.10 https://www.b4x.com/android/help/json.html
B4X:
Dim JSON As JSONParser
JSON.Initialize(Job.GetString)
Dim Map1 As Map
Map1 = JSON.NextObject
EditTextBC.Text = Map1.Get("barcode")
EditTextResponse.Text = Map1.Get("marking")
LabelError.Text = Map1.Get("error")
