Note:
This happens when: DrawLinesOnPanel(Panel2)

B4X:

CanvasHolder.drawline(0,setting_label.top-5,382,setting_label.top-5, Colors.RGB(127,176,0), 1)

then can not over-write the text as above.

Are you using the canvas to add an underline to the text?

There are simpler ways: https://www.b4x.com/android/forum/threads/class-richstring.48573/#content

Here is the setting page on my app.
The problem is with the "Sound On" button.
Off over-writes "On" on the screen.
as you can see.

The problem is the Canvas, it duplicates the content.
Without the Canvas it works as expected.
Instead of drawing lines with a Canvas you could add Panels with a height of 1 to show lines.

How do i add the panels to the scrollview that is there?
Also not clear the correct way to define the panels.

B4X:

NavControl.ShowPage(page11)
    ScrollView2.Panel.LoadLayout("page10")
    ScrollView2.ContentHeight = Panel2.Height
    ScrollView2.ContentWidth = Panel2.Width
    DrawLinesOnPanel(Panel2)

Why aren't you using CustomListView? Which layout are you trying to implement?

This is the menu i am trying to implement
with the lines separating each text item and image.
it worked fine as a scrollview/panel but now with
the drawlines it does not let me correctly change
the text in "Sound on" - "Sound - Off"
example above.

Try this one:

But as Erel suggested, CustomListView would be the better choice.
