Design a menu XML as below:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <item
        android:id="@+id/action_star"
        android:title="Star"
        app:showAsAction="always">
    </item>

    <item
        android:id="@+id/action_save"
        android:title="Save"
        app:showAsAction="never">
    </item>

    <item
        android:id="@+id/action_color"
        android:title="Color"
        app:showAsAction="never">
    </item>

    <item
        android:id="@+id/action_about"
        android:title="About"
        app:showAsAction="never">
    </item>

    <item
        android:id="@+id/action_share"
        android:title="Share"
        app:showAsAction="never">
    </item>

    <item
        android:id="@+id/action_clear"
        android:title="Clear"
        app:showAsAction="never">
    </item>
</menu>
