Answer 1

By default the theme which is set in Manifest's tag is used to set theme of an activity declared which not having any theme.

You should apply your mentioned theme in Application's theme attribute in Manifest.

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:theme="@style/CustomToolbarStyle">
.....
</application>

And this theme will be overriden by the theme which you set in Activity tag's theme attribute in Manifest or theme which is set from Activity's layout, again by theme attribute.

You have to define this theme for other activities too in your manifest

<activity
android:name=".YourActivityName"
android:theme="@style/CustomToolbarStyle"/>
