Create custom view and display in Layout Preview

Question

I've been creating custom views for a while now, but never got to make them in a way that the Android Studio preview displays them correctly.

I initialize the custom attributes using:

if (!isInEditMode()) {
...
}

But this results in an invisible component on preview. Any ideas on how to achieve this?

You need to rebuild project. After that custom views in preview will work

Have a look here. I don't think you need to use that if statement. I never used it, and views always get displayed in previews

Thanks for the info, I use isInEditMode, because if I don't the preview displays an error suggesting to use that. So I'm not sure what stuff can be done or not in a view constructor in order to avoid these errors. – Maximiliano Ambrosini Feb 17 '17 at 14:37

When inflating your layout in your custom View clss, try with attachToRoot set to true.
