Android Question keep a selection of an CusromListView

[HansDieter]

If i select line in an CustomListView, the CustomListView_ItemClick events fires and the line gets unselected automatically.
But i want to keep the selection visibel.
How is this to do?

How is this to do?

Private Sub CustomListView1_ItemClick (Index As Int, Value As Object)
    
    For i = 0 To CustomListView1.Size -1
        
        If i = Index Then
            CustomListView1.GetPanel(i).Color = CustomListView1.PressedColor 'Your Selected Color
            Else
            CustomListView1.GetPanel(i).Color = CustomListView1.DefaultTextBackgroundColor 'Your default Background color
        End If
        
    Next
    
End Sub

[B4X] CLVSelections - extended selection modes for xCustomListView

This class extends xCustomListView library and adds more selection modes: MODE_SINGLE_ITEM_TEMP - The same as the default behavior. MODE_SINGLE_ITEM_PERMANENT - Single item is selected and the selection remains. MODE_MULTIPLE_ITEMS- Multiple items can be selected. There is also a helper method...

Another way should you like to keep the selection pressed color untill selected again so you can select multi items is to use the ItemLongClick without having to iterate over the items and therefore leave the ItemClick even for something else:

Sub Clv1_ItemLongClick (Index As Int, Value As Object)
    If clv1.GetPanel(Index).Color= clv1.PressedColor Then
        clv1.GetPanel(Index).Color = clv1.DefaultTextBackgroundColor
    Else
        clv1.GetPanel(Index).Color= clv1.PressedColor
    End If
End Sub

Please note that the extended selection in CLVSelections class offers that feature too.

wasn't color a writeonly property?

No!!!

and clvs initialized by code aint got pressedcolor

yes, because to initiate a custom view via code, you have to pass a map with the properties.
