更改默认导航抽屉的图标大小

Question

尝试更改默认导航抽屉的图标大小并在每个项目后添加分隔符，但我不明白如何执行此操作？这是菜单抽屉视图：

<group android:checkableBehavior="single">
    <item
        android:id="@+id/agenda"
        android:icon="@drawable/agenda"
        android:title="AGENDA"
        />
    <item
        android:id="@+id/speakers"
        android:icon="@drawable/speakers"
        android:title="SPEAKERS" />
    <item
        android:id="@+id/schedule"
        android:icon="@drawable/schedule"
        android:title="SCHEDULE" />
    <item
        android:id="@+id/organiser"
        android:icon="@drawable/organiser"
        android:title="ORGANISER" />
    <item
        android:id="@+id/partners"
        android:icon="@drawable/partner"
        android:title="PARTNERS" />
    <item
        android:id="@+id/event_info"
        android:icon="@drawable/eventinfo"
        android:title="EVENT-INFO" />
</group>

这是 dimens.xml

<resources>
    <!-- Default screen margins, per the Android Design guidelines. -->
    <dimen name="activity_horizontal_margin">16dp</dimen>
    <dimen name="activity_vertical_margin">16dp</dimen>
    <!-- Default screen margins, per the Android Design guidelines. -->
    <dimen name="nav_header_vertical_spacing">16dp</dimen>
    <dimen name="nav_header_height">160dp</dimen>
</resources>

Answer 1

在 dimens.xml 中设置 design_navigation_icon_size 和 design_navigation_icon_padding 对我有用。

/values/dimens.xml

<dimen name="design_navigation_icon_size" tools:override="true">10dp</dimen>
<dimen name="design_navigation_icon_padding" tools:override="true">10dp</dimen>
