How to change padding and margin values ​​of menu items?

Question

Java

Can you please tell me how to change the distances (padding and margin) of the elements in the menu? I need to reduce them. standard distances are too big for the application.
I create the menu like this:

<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" tools:context=".MainActivity">

    <item android:id="@+id/menu_contents"
        android:title="@string/menu_contents"
        android:icon="@drawable/ic_format_list_numbered"
        android:orderInCategory="2"
        app:showAsAction="always" />

    <item android:id="@+id/menu_search"
        android:title="@string/menu_search"
        android:icon="@drawable/ic_search"
        android:orderInCategory="100"
        app:showAsAction="always" />

    <item android:id="@+id/menu_favorite"
        android:title="@string/menu_favorite"
        android:orderInCategory="100"
        app:showAsAction="never" />

    <item android:id="@+id/menu_settings"
        android:title="@string/menu_settings"
        android:orderInCategory="100"
        app:showAsAction="never" />
</menu>

Thank you very much in advance!
