Programmatically AddView question

[bhark54]

I have a program that I programattically add a panel view. I would then like to add buttons programattically that are children of the panel. Do I just panel.addview(... ?

panel1.Initialize("")
panel1.Color = Colors.Cyan
Activity.AddView(panel1,0,70%y,100%x,30%y)

panel1.AddView(btn.....

The above does not work.

If I don't make the panel and just do Activity.AddView(btn.... it works (but no panel of course).

How do I programattically do addview to create a child view?

Are you creating the panel before adding it to the Activity?

Here's an example of creating buttons at runtime:

Like NJdude suggested, Add the panel to the activity first and then draw the buttons to the panel.

The problem isn't not knowing how to create views programattacially it is how to make a view a child of another view.
In the listing above I can create a panel (via addview) but then I want to programattically create buttons that are children of the panel. I thought I could just do panel1.addvie(btn,.... after already successfully executing activity.addview(panel1,... ) but that does not work. The buttons do not show up. I will write a complete example after I get home from work this evening. Thanks.

You must also initialize the Buttons before adding them to the Panel.

Best regards.

Success! Creates 30 buttons that are children of panel. Pressing button sets label text. This is part of custom keyboard logic for a flight log app I am working on. Thanks for the help.

Sub Globals
    Dim panel1 As Panel
   Dim label1 As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("main")
panel1.Initialize("")
Activity.AddView(panel1,0,50%x,100%y,100dip)
label1.Initialize("")
Activity.AddView(label1,0,0,100%y,100)
panel1.Color = Colors.Gray
btnwidth = Activity.Width * 0.1
For row = 0 To 2
   For col = 0 To 9
      Dim btn1 As Button
      btn1.initialize("btnevent")
      panel1.AddView(btn1,col*btnwidth,row*btnwidth,btnwidth,btnwidth)
      btn1.TextSize = 7
      btn1.Text = row&col
      btn1.tag = row&col
   Next 
Next
End Sub
Sub Activity_Resume
If Activity.Width > Activity.Height Then
   panel1.Top = 45%y
   panel1.Width = 100%x
   panel1.Height = 55%y
End If
End Sub
Sub Activity_Pause (UserClosed As Boolean)
End Sub
Sub btnevent_Click
   Dim send As Button
   send = Sender
   label1.Text = send.tag
End Sub

Addview with a panel

I'm exactly having that problem with adding a progress bar and a label to a panel.

I initiize it first, but, I dont see the progress bar or the label?? I'm stuck. - Thanks for any help

Dim GradBk As GradientDrawable 
   Dim Gb As GradientDrawable 
   '
   GradBk.Initialize("LEFT_RIGHT", Array As Int (Colors.RGB(238,232,170), Colors.RGB(238,221,130)))
   ProgressPanel.Initialize("Progress")
   ProgressPanel.Background = GradBk
   ProgressPanel.BringToFront 
   ProgressPanel.Visible = True
   Activity.AddView(ProgressPanel, 0, (100%y/2)-40dip,100%x,60dip)
   '
   Prog.Initialize("Progress")
   Gb.Initialize("TOP_BOTTOM", Array As Int (Colors.Yellow , Colors.RGB(184,134,11)))
   Gb.CornerRadius = 3dip
   SetProgressDrawable(Prog,Gb)
   Prog.Progress = 0
   ProgressPanel.AddView(Prog, 10dip, (100%y/2), 100%x-20dip, 5dip)
   '
   ProgLbl.Initialize("Progress")
   ProgLbl.Text = "One Moment Please..."
   ProgLbl.TextColor = Colors.Black 
   ProgressPanel.AddView (ProgLbl, 30, (100%y/2)-20dip, 240dip, 30dip)

Note that you can use 50%y instead of 100%y/2.

Maybe the progress bar is hidden by another view.

You are missing 'dip' here:

ProgressPanel.AddView (ProgLbl, 30, (100%y/2)-20dip, 240dip, 30dip)

Thank you, I'll check that out and see if that is the problem. Thanks for the tips too!

Could you post your project as a zip file ?
It would be much easier to help you if could see what you have done and how.

Best regards.
