Try to change in styles.xml this:

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

to this:

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

I had the same problem and to resolve it you need to temporally downgrade

compileSdkVersion 28 -> 27
targetSdkVersion 28 -> 27

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3' --> 27.1.1
implementation 'com.android.support:design:28.0.0-alpha3' --> 27.1.1
implementation 'com.android.support:cardview-v7:28.0.0-alpha3' --> 27.1.1

I think there is a problem on those library when Android Studio have to render XML layout.

Alternatively, Google released yesterday Android Studio 3.2.0 Upgrade your IDE, change support libraries with 28.0.0 and everything will work

Maybe there was some other libraries which broke the rendering but upgrading Android Studio is the best solution if you want to support API 28 — Lorenzo Vincenzi, Sep 27 '18 at 12:41
