Android Tutorial List with two columns and a checkbox

Hello,

I have a TabHost which holds 4 tabs.
I want to have a list with two columns and a checkbox for each line in the list on the forth tab of the TabHost.

How can I do it? In case it's not possible - how can I do it without the checkboxes?

Thank you for your help,
Elad.

Hi,
Exist a way, using this example of a list with checkboxes, for position the scrollview to the end of the list?

Thanks

ScrollView1.ScrollPosition = height * MaxNumberOfItems

Thanks, but doese not work
I would that the line should reach on the last entered value (in questoa test on "Word100").

Sub Process_Globals
End Sub
Sub Globals
    Dim ScrollView1 As ScrollView
    Dim lstChecks As List
    Dim height As Int
    height = 20dip
End Sub
Sub Activity_Create(FirstTime As Boolean)
'Test for list into ScrollView
    ScrollView1.Initialize(0)
    Dim pnl As Panel
    pnl = ScrollView1.Panel
    Activity.AddView(ScrollView1, 0, 0, 100%x, 50%y)
    lstChecks.Initialize
  
    For i = 1 To 100
        Dim chk As CheckBox
        chk.Initialize("")
  
        chk.Text = "Word" &  i
        chk.Enabled=False
      
        chk.Gravity=Gravity.LEFT
        lstChecks.Add(chk)
        Dim lbl1 As Label
        lbl1.Initialize("")
        lbl1.Text =  i
        lbl1.Gravity = Gravity.RIGHT
        chk.TextColor=Colors.White
        lbl1.TextColor=Colors.Green
      
          pnl.AddView(chk, 0, height * (i - 1), 120dip, height)
        pnl.AddView(lbl1, 150dip, height * (i - 1), 150dip, height)
      
    Next
    pnl.height = lstChecks.Size * height
    ScrollView1.ScrollPosition = height * 100
    'ScrollView1.ScrollPosition = height * pnl.NumberOfViews-1
End Sub

... it could be because is declare:

pnl = ScrollView1.Panel

?

Wait!... Ok Thanks you. I had insert a DoEvents and it Work

...
...
...
    Next
    pnl.height = lstChecks.Size * height
    DoEvents
  ScrollView1.ScrollPosition = height * pnl.NumberOfViews-1
End Sub

This is not supported by ListView.
For a simple list with checkboxes you can use InputMultiList dialog.
However in your case I recommend you to use a ScrollView.
Here is an example of a list with checkboxes:

Hello.
I know that the thread is old, but it remail useful.
This part of code is not working in v4:

lstChecks.Add(chk)

and

chk = lstProducts.Get(i)

Which is the correct method in order to add the checkbox in the listview and get the current checkbox?
Regards

You shouldn't use the code from this tutorial. There are much better options now.

CustomListView is one of them: [Class] CustomListView - A flexible list based on ScrollView

This is great!
But requires a newer version from version I have (v4)
