Add theme attribute to the activity where you want to hide appbar in manifest file

        <activity
            android:name="com.mvvm.Activity"
            android:label="@string/app_name"
            android:theme="@style/NewTheme">
        </activity>

then create a new theme in style.xml with parent as Theme.AppCompat.NoActionBar

 <style name="NewTheme" parent="Theme.AppCompat.NoActionBar">
    
   </style>

This question is already answered here:-

How to remove it from all activities

How to remove it from specific activity

In Case if none of them work fine for you then try this:-

For specific activity,

Set theme in manifest file as mentioned below:-

<activity android:name=".activity.ContinueLoginActivity"
android:theme="@style/Theme.AppCompat.Light.NoActionBar"
android:screenOrientation="portrait" />

Programmatically :-

Kotlin:

supportActionBar?.hide()

Java:

if (getSupportActionBar() != null) {
    getSupportActionBar().hide();
}

for remove it from all activities change .DarkActionBar by .NoActionBar in style.xml file:-

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

</style>
