Custom Toolbar popupTheme, override

android:layout_marginStart android:layout_marginEnd

First add this lines to your res/values/styles.xml

<style name="PopupTheme" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:layout_marginStart">2dp</item>
    <item name="android:layout_marginEnd">2dp</item>
</style>

then set Toolbar's popupTheme to 'PopupTheme' as shown above, just like this:

......
<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@color/colorPrimary"
    app:navigationIcon="@drawable/arrow_back"
    android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
    app:popupTheme="@style/PopupTheme"
    app:title="@string/toolbar_title"/>
......

Cheers!
