Android Studio is not showing Design Preview But Application is running

Question

I have updated my android studio. In my layout preview my design is not showing it says

NOTE: One or more layouts are missing the layout_width and layout_height attributes, required in most layouts.

OR: Automatically add all missing attributes. There is no error in application. It's running well. I have uninstalled my android studio but same issue occurred. In all my projects occurs the same issue.

I have updated SDK as well.

Here is layout.xml

Please try to invalidate and restart, sometimes it also removes problem if there's nothing wrong in the layout file. — Parthiv Mistri, Oct 24 '18 at 06:30

This happens to me sometimes. What I do to fix this is to check styles.xml from res folder and check that the style AppTheme is correctly defined.

For example, if I want my app style to be without action bar, I use this as AppTheme:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

... and add required items such as colorPrimary etc.

Then after rebuilding the gradle I usually can see my layout design again

One of the possibility is that your Theme changes. Try changing it to Material -> Dark in the Preview view.
