Android - Actionbar not showing in the development preview

Question

Actionbar not showing in the development preview but showing normally after running the app, minimum api is 15, tried to delete the them from the manifest file, didn\'t show

Answer 1

Check which theme is selected on the top of the XML preview screen.

Even if you're using Eclipse, it will look similar.

Your application is displaying the ActionBar because your AndroidManifest has a theme which displays the ActionBar.

Answer 2

if you are talking about the preview screen of the android studio/eclipse then note that you can change your theme in the top of the preview, you must have a theme with NoActionBar .

Answer 3

try this

values/themes.xml

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

 </style>

and assigns the item in the manifest

<activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/Theme.Mytheme">
 </activity>

If you can't see the action bar AND also the status bar or buttons, it could be because the "Show Layout Decorations" options is turned off in the Layout Editor. Just check this option and everything should be displayed again. As per Android Studio 3.3:
