Android Question accessing xGauges in CustomListView?

[zak]

Hello. I created a layout in the designer with a xGauges Class from (https://www.b4x.com/android/forum/threads/b4x-xui-xgauges-class.98932/#content), and tried to insert the layout into a CustomListView, but was unable to individually access each xGauge. For example the below code:

    Sub CheckBox1_CheckedChange(Checked As Boolean)
    Dim index As Int = CLV1.GetItemFromView(Sender)
    Dim pnl As B4XView = CLV1.GetPanel(index)
    Dim xgau As xGauges = pnl.GetView(index)
    xgau.Value= 50

would give a 'Types do not match warning' and a 'java.lang.RuntimeException: Field: ba not found in: android.widget.CheckBox' error

any idea on how to do it?

It would be easier to help you if you posted your project or better a small project showing the problem.

pnl.GetView will never return a custom view instance.

One solution:

Add this line to DesignerCreateView:

pnlGauge.Tag = Me

Change your code to:

Dim xgau As xGauges = pnl.GetView(index).Tag

Tx. The needle is now rotating to the new value. However properties like GaugeTitle or GaugeUnit are not dynamically taking on new values:

Sub CheckBox1_CheckedChange(Checked As Boolean)
    Dim index As Int = CLV1.GetItemFromView(Sender)
    Dim pnl As B4XView = CLV1.GetPanel(index)
    Dim xgau As xGauges = pnl.GetView(index)
    xgau.Value= 50  'working
    xgau.GaugeTitle="Consumption"   'not working
    xgau.GaugeUnit= "Kwh"     'not working

You should start a new thread for any new question/issue.

I see it too.
Can you please test the attached class file.
I will update the Class thread tomorrow.

EDIT: removed the xGauges.bas file.
The xGauges thread has been updated in the first post.
