Layout Editor: Vertical/Horizontal Dashed/dotted lines

[Bill_]

Hi,

A few years I created a simple app. I don't remember what version of Android Studio I used. The app has worked fine. A few days ago I installed Dolphin 2021.3.1 and successfully walked through some tutorials.

To make some changes to my simple app I opened it. The attachment shows 2 vertical and 1 horizontal dashed/dotted lines in the Layout Editor, that I annotated with yellow arrows,.

Deleting all constraints and dragging the lines away from the area made them disappear.

Question: what did I do to cause the dashed/dotted lines, to show up?.

Thanks,
Bill

Hi,

The PDF file doesn't contain any code. It contains a screen capture of the Layout editor.

Today I clicked on the Image icon/button, above, thinking AndroidForums would let me paste the image inline/here, but it wanted a URL.

This is a PNG version of the Layout Editor, though it is a little blurrier than the PDF.

Thanks,
Bill

I discovered the answer.

They are Guidelines.

In the Layout Editor, on the same icon row with the eyeball and U, etc. At the end, in what I see, is something that looks like an capital i.

I didn't knowingly want them.

I deleted them by selecting each and pressing [Delete].
