Android Studio does not show layout preview

Choose another theme (other than Holo, for example Theme)

When you create the style incorrectly or from an existing style, this problem usually occurs. So select the "Graphical Layout" select "AppTheme" (The tab with a blue star). And select any of the predefined style. In my case "Light" which should resolve the problem.

Try to 'Invalidate caches & restart'.

Restart your Android Studio by choosing this option. It may take some time.

Then, if still doesn't work try to rebuild your project.

This is a common problem . It can be easily solved by changing res/values/styles.xml to

<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>

Steps :

• Go to res/values/

• open styles.xml

  • change from -> style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"

  • change to -> style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar"

  (Just prepend "Base." to "Theme".)

• Save the file and check Preview now.

• Preview Works Perfeclty now.

Check again for SDK update because API 23: Android N (preview) is now available, download it properly OR select the API 23: Android 6.0 from the top right of the preview window. check the image

.
.
It (Android Studio) automatically selects the latest one even if it not properly installed. So,

What you need to do is :

1. install the new one properly

   OR

2. click on the previous one.

Find Styles.xml in Values.(res/Values/Styles.xml) Change this

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

to this:

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

Then clean and build project. Both of those you can do from build menu.

It worked for me.
