    <resources>
        <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
            <item name="android:layout_width">fill_parent</item>
            <item name="android:layout_height">wrap_content</item>
            <!--<item name="android:textColor">#00FF00</item>-->
            <!--<item name="android:typeface">monospace</item>-->
        </style>
    </resources>

//AND Code for build.gradle Module:app is

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.madhav.schoolmanagement"

        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

In your screen shot, there is an red circle with exclamatory mark (next to zoom buttons). Click on that you will get some idea why preview is not showing. — sohel yadav, Feb 20 '19 at 08:04

Default styles.xml should look like this

<resources>

<!-- Base application theme. -->
<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>

</resources>

I think you have not Updated your Android Studio. And Solution for this is Base.Theme.AppCompat.Light.NoActionBar
