Android Question xCustomlistview & xGauges update value

mtselection · Apr 5, 2022

Hi,

I try to use xCustomlistview with xGauges v 1.8 and the code is as follows:

B4X:

    Dim user As showtype
    Dim lbtest As String
    clv1.Clear
    If userdata.showlist.Size>0 Then
        Dim calc As Double
        Dim str As String
        For i=0 To userdata.showlist.Size-1
            Dim p As B4XView = xui.CreatePanel("")
            Dim width As Int = 100%x
            Dim height As Int
            user=userdata.showlist.Get(i)
            If user.viewtype>2 And user.viewtype<6 Then
                height = 25%y
                p.SetLayoutAnimated(0, 0, 0, width, height)
                p.Color=Colors.ARGB(255,39,116,124)
                xGauges1.Initialize(Me,"xgauges")
                xGauges1.AddToParent(p, 30dip, 0, GaugeWidth)
                ......

in update

B4X:

Sub updatedata (val As String)
    If userdata.showlist.Size>0 Then
        Dim data() As String
        data = Regex.Split(",", val)
        Dim v As Double
        Dim typ As showtype
        For i=0 To userdata.showlist.Size-1
            
            typ = userdata.showlist.Get(i)
            v=data(typ.byteindex)
            If typ.viewtype>2 And typ.viewtype<6 Then
                Dim pnl As B4XView = clv1.GetPanel(i)
                xGauges1 = pnl.GetView(0).Tag
                xGauges1.Value=v
                Dim lbl As Label = pnl.GetView(2)
                lbl.Text=v
            End If
        Next
    End If
End Sub

In debug I check the xGauges1 = pnl.GetView(0).Tag is null and
in XGauges1.Value=v I received this error:
java.lang.reflect.InvocationTargetException
at java.lang.reflect.Method.invoke(Native Method)

Thanks

Start with: [B4X] How to get <custom view here> from <CLV or any other container> -

Klaus will say whether xGauges assigns the class instance to the base tag. If not then you can do something similar yourself.

xGauges assigns the class instance to the base tag.

Thanks Erel,Klaus

I use this code in update:

B4X:

                Dim pnl As B4XView = clv1.GetPanel(i)
                For Each v As B4XView In pnl.GetAllViewsRecursive
                    If v.Tag Is xGauges Then
                        v.Tag.As(xGauges).Value = d
                    End If
                Next

but the v.Tag not return the xGauges class instance.

During the xclv creation I add 1 xGauges and 2 Labels, but this code return 3 panels (of xGauges), 2 labels and no Tag.

Thanks

Ok, solved

code in creation:

B4X:

            Dim p As B4XView = xui.CreatePanel("")
            Dim width As Int = 100%x
            Dim height As Int
            user=userdata.showlist.Get(i)
            If user.viewtype>2 And user.viewtype<6 Then
                height = 25%y
                p.SetLayoutAnimated(0, 0, 0, width, height)
                p.Color=Colors.ARGB(255,39,116,124)
                Dim xgau As xGauges
                xgau.Initialize(Me,"xgauges")
                xgau.AddToParent(p, 30dip, 0, GaugeWidth)
                p.Tag=xgau
                xgau.BackgroundColor=Colors.Transparent

code in update:

B4X:

        Dim data() As String
        data = Regex.Split(",", val)
        Dim d As Double
        Dim typ As showtype
        For i=0 To userdata.showlist.Size-1
            typ = userdata.showlist.Get(i)
            d=data(typ.byteindex)
            If typ.viewtype>2 And typ.viewtype<6 Then
                Dim pnl As B4XView = clv1.GetPanel(i)
                Dim xgau As xGauges = pnl.Tag
                xgau.Value = d
                Dim lbl As Label = pnl.GetView(2)
                lbl.Text=d
            End If
        Next
