Android Tutorial Creating a table view based on ScrollView

A much improved version is available here.

You can use the code in this example to show data in tabular form.

The table is made of two main views. The header row is made of a panel with labels. The main cells component is made of a ScrollView with labels as the cells.

You can modify the code to change the table appearance.
Some of the settings can be changed in Sub Globals:

    'Table settings
    HeaderColor = Colors.Gray
    NumberOfColumns = 4
    RowHeight = 30dip
    TableColor = Colors.White
    FontColor = Colors.Black
    HeaderFontColor = Colors.White
    FontSize = 14

Adding data to the table:

    'add header
    SetHeader(Array As String("Col1", "Col2", "Col3", "Col4"))
    'add rows
    For i = 1 To 100
        AddRow(Array As String(i, "Some text", i * 2, "abc"))
    Next
    'set the value of a specific cell
    SetCell(0, 3, "New value")
    'get the value 
    Log("Cell (1, 2) value = " & GetCell(1, 2))

Table events:

Sub Cell_Click
    Dim rc As RowCol
    Dim l As Label
    l = Sender
    rc = l.Tag
    activity.Title = "Cell clicked: (" & rc.Row & ", " & rc.Col & ")"
End Sub
Sub Header_Click
    Dim l As Label
    Dim col As Int
    l = Sender
    col = l.Tag
    Activity.Title = "Header clicked: " & col
End Sub

The code is not too complicated and you can further customize it as needed.

Thank you but this dont works, same error message

 

[ykucuk]

I try it this way and that works for me

Sub GetView(Row As Int, Col As Int) As Label
    Dim l As Label
    l.Initialize("")
'    ScrollView1.Initialize(100%x)
    'add header
    SetHeader(Array As String("AccountID", "Forename", "Surname", "Phone"))

'    l = Table.GetView(Row * NumberOfColumns + Col)
    Return l
End Sub

Sorry, but I don't understand what you want to do ?
Why do you add SetHeader(ArrayAsString("AccountID", "Forename", "Surname", "Phone")) ?
The GetView routine should return the Label at the given row and column in the Table.
Your routine returns a Label which is not added to a parent view !

i want to load all information from a database using webservice.
When i load my webservice, then i got a XML File and with the xml parser i search for the wanted information and load it in the scrollview.
You say you are from switzerland, can you speak german? my english isnt good

 

[klaus]

can you speak german?

Ja.

You can ask the qustion in the german forum.
Du kannst die Frage im Deuschen Forum stellen.

 

[ykucuk]

ok

 

[ykucuk]

When i click on a Row, how can i get the typed Information out of the Scrollview?
i want to fill Edittext with the Information

 

[klaus]

Which version of the Table class are you using ?
Note that you can find a more improved Table class here Flexible Table class.

 

[ykucuk]

i use the same in the Table Example 1.2

Unfortunately, you don't give enough information.
How do you fill the Tables?
Did you copy the Table code in your main code?

Hi Klaus, Thanks for the response, I have found the problem, which is when the initialization label on Scrollview.
