In Activity file I did add Objects.requireNonNull(getSupportActionBar()).hide()

But regardless this bug still happens, how do I hide the actionbar?

The actionbar was hidden until I implemented the Nav Drawer feature

And YES, I do want to implement Nav Drawer without ToolBar
By the way, I am doing this on API 26

Is there anything wrong in placement of views?

Create a custom theme that extends the base theme you are using in the app and removes the ActionBar. Add the following code to your styles.xml file

<style name="AppTheme.NoActionBar" parent="AppTheme">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>

Make sure you have the Theme.AppCompat family of themes set as the activity's theme in the manifest file (AndroidManifest.xml

<activity
android:name=".ui.ui_elements.HomeActivity"
android:theme="@style/AppTheme.NoActionBar"
>
