custom views must be treated differently than native views, here is an important article about it:

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

This is a common question and for a good reason. Custom views classes are not views by themselves. The views tree only holds views. This means that this code cannot work: Dim B4XFloatTextField1 As B4XFloatTextField = CLV.GetPanel(x).GetView(y) The actual view that is added to the views tree...

This is the code you need:

For Each tf As B4XView In Pane1.GetAllViewsRecursive
        If tf.Tag Is B4XFloatTextField Then
            Log(tf.Tag.As(B4XFloatTextField).Text)
            Log(tf.Tag.As(B4XFloatTextField).Tag)
        End If
    Next

But you can also do it this way:

    For Each tf As B4XView In Pane1.GetAllViewsRecursive
        If tf.Tag Is B4XFloatTextField Then
            Dim xftf As B4XFloatTextField = tf.Tag
            Log(xftf.Text)
            Log(xftf.Tag)
        End If
    Next
