Android Question How to Load String value into B4x table?

[Pravee7094]

Hi team,
If you want to load the data in to B4x table, You just make the data as List.
but here, I wanna load one string value in to B4x table.
How to do it? I tried but no success
Here is the code.

Sub ic_customcamera_result_found(result As String)
        Dim root As List
        root.Initialize
        For Each colroot As Map In root
            barcode_result = colroot.Get(result)
            root.Add(barcode_result)
        Next
        B4xtable.SetData(root)
    End If
    
End Sub

Any Suggestion or Help.

Regards
Praveen

Dim root As List
        root.Initialize
        For Each colroot As Map In root
            root.Add(Array(colroot.Get(result)))
        Next
        B4xtable.SetData(root)

Thanks for your suggestion sir,
I found result. Here

        Dim root As List
        root.Initialize
        
            Dim row(1) As Object
            row(0) = result
            root.Add(row)
        
        printDataTable.SetData(root)

But Have one Doubt sir,
How do I write in Loop sir, This is little confusion for me.
I tried with resultset but I don't want any data fetch from database. so How to use while loop to go print next value on next row sir.
Here is sample code.

        Dim root As List
        root.Initialize
        Do While (how to go with next row)
            Dim row(1) As Object
            row(0) = result
            root.Add(row)
        Loop
        printDataTable.SetData(root)

Any body Help!

Thanks

If your data is coming from a list, you can do this:

Dim MyList As List
    MyList.Initialize
    MyList = Array ("Apple", "Banana", "Cherry", "Coconut", "Grapes", "Lemon", "Mango", "Melon")
    Dim data As List
    data.Initialize
  
    For Each s As String In MyList
        Dim r(1) As String
        r(0)=s
        data.Add(r)
    Next
    B4XTable1.SetData(data)
   'or this:
    For i=0 To MyList.Size-1
        Dim r(1) As String
        r(0)=MyList.Get(i)
        data.Add(r)
    Next
    B4XTable1.SetData(data)

But I didn't load the data from the list. My concept is Scan the one barcode and It will appear on the table.
Problem is I can add the only one data.
For example, First I go to scan the one barcode and it will successfully add the table. and Again I go to scan the another one barcode that will also
appear in the table. But First barcode number is deleted. I mean second barcode number replace the first barcode number.

But I want to print the second barcode on second row, then If I go to scan the third barcode, and it will appear on the 3rd Barcode. No data will be replaced.
Here is the sample code:

    Private ic_customcamera As QRCodeReaderView

Sub btn_resultbarcode_Click
'    ilbl_resultfirst.Text = ""
    ip_camerabarcodescannerpanel.Visible = True
    Panel1.Visible = False
    ic_customcamera.Visible = True
    ic_customcamera.startScan
End Sub

Sub ic_customcamera_result_found(result As String)
    ilbl_resultfirst.Text = result
    If ilbl_resultfirst.Text <> "" Then
        ic_customcamera.stopScan
        ic_customcamera.Visible = False
        ip_camerabarcodescannerpanel.Visible = False
        Panel1.Visible = True

        Dim root As List
        root.Initialize

            Dim row(1) As Object
            row(0) = result
            root.Add(row)

    B4xTable.SetData(root)
   
End Sub

Any suggestion or Help! Please

To display the scanned barcode in the in-memory table and B4XTable, you can do this every time you scan a barcode. But once you exit the app, you will lose that new data , unless you make sure to save it to a list or SQLite database in the device so next time you enter your app., the data you entered earlier appears.

Sub ic_customcamera_result_found(result As String)
    ilbl_resultfirst.Text = result
    If ilbl_resultfirst.Text <> "" Then
        ic_customcamera.stopScan
        ic_customcamera.Visible = False
        ip_camerabarcodescannerpanel.Visible = False
        Panel1.Visible = True

        Dim row(1) As Object
        row(0) = result 
        B4XTable.sql1.ExecNonQuery2($"INSERT INTO data VALUES( ?)"$, row)
        B4XTable.ClearDataView
    End If
End Sub

Thanks for your suggestion.
But My problem is different.
Using B4X table. If I scan one barcode, the barcode value correctly appear in the first row in B4X Table. Thats fine.
And Again I go to scan the another one barcode, the second value should appear in second row. But Second value replace the first value and
appear in the first row.
I just want, How many barcode I scan all the values appear in the correct row, I mean 1st scan barcode in the first row, 2nd scan barcode in the second row, 3rd ...... thats like.

First of all without saving the data in list or sqlite this above concept is possible or not?

Any suggestion or Help?

The code I gave you saves the scanned text to the next row available to the memory database and shows it in the B4XTable in the order you scanned them. If the table has no rows to begin with, then, the barcode shows up in the first row and so on. If the table already has data, the scanned barcode shows up at the end of the table immediately. If your current project replaces the first scanned barcode with the second and you lose the first one, then, something you are doing is making it replace the first with the second.
If you want to create a small project substituting the barcode part with manual text, without using barcodes since I have not used that barcode library, I or someone else will look at it and try to help. If that is not possible, then export your project as is.
