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

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

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
