iOS Question [B4X] Get the label from an TextItem of a CustomListView

[Mike1970]

Hi everyone, it is possibile to get a reference of the label used for the "TextItem" of a CustomListView?

i wish to change the backgroud color of the label, text size, round the corners etc..

I know that there is the .DesignerLabel method, but if i try to change color it does not work

Thanks in advance

I do not play with B4i and have not a clue if this answers your question , but ....

in B4A ...

Dim pnl As B4XView = clv1.GetPanel(Index)
pnl.getview(0).Text = "abc"    'index(0) is the panel label populated using  .AddTextItem method

Cannot comment on setting other Label properties in B4i

Change a row in an xCustomListView

Hello I am trying to change the background color of an item in an xCustomListView. I've searched but can't find any method other than changing the whole view. I would like to have certain elements of the list highlighted. Also can I change the default height of all elements in the view...

'Lets load the screen for the item layout
Pnl.LoadLayout("layout1")

label1.Text = "This is the label text "
label1.color = Colors.Blue
label1.TextColor = Colors.Black

Once the layout is loaded, you will have access to the views/controls in the layout.

No I don’t load any layout , I use this

Clv.AddTextItem(“hello”,”hello”)

So you are saying to cycle all the element and do it one by one, right?

My intention was to customize the label used in the library it self. Because the element are added wit

clv.AddTextItem(“hello”,1)

so it mean that there is a label inside the library.
Infact there is a method “.DesignerLabel” that somethings like Font, textColor let you to change.

but for example a need to change the background color of the label, but it does not work

 

[gmoriwaki]

Dim item As CLVItem = clv1.GetRawListItem(Index)

'Every custom list view has a panel within    
Dim p As Panel = item.Panel.GetView(0)

''This is the label item 
Dim lbl As Label = p.GetView(0)

'Now you can access those elements
lbl.Text = "Change the text of the label"

'Change the label text color
lbl.TextColor = Colors.Black

This is still new to me, but this is how I do it.

There are two ways you can do this ... Loop thru the CLV once you have filled it ...

For i = 0 to clv1.Size -1
Dim p As B4XView = clv1.GetPanel(i)
p.GetView(0).Color = '.........  your text Label

Or Immediately after you have called .AddTextItem(....).

clv1.AddTextItem("Hello", "")
Dim p As B4XView = clv1.GetPanel(clv1.Size -1)
p.GetView(0).Color = '............. your text Label

*** But I do Not know how to change Label Properties in B4i (is it any different ?)

so it mean that there is a label inside the library.

When you call clv.AddTextItem() , a Row/Panel/Pane is added and the Text is displayed in a Label (index 0).
