Question

android studio 3.3 not showing action bar and status bar in its preview window after creating new project.i already tried this in build.graadle(module:app) file (implementation'com.android.support:appcompat-v7:28.0.0-alpha1')

Answer 1

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Try this on your styles.xml

Answer 2

In the preview tab, click on the eye and select 'Show Layout Decorations'.

EDIT: Toolbar isn't showing because of my style settings - I used 'NoActionBar'. This should work for you, though.
