如何更改设计支持库的导航抽屉菜单项布局的部分

Question

I am talking about the Design Support Library here. I am trying to change things like:

• selected menu-item background color
• distance between icon and text

I tried a lot but I can seem to find any solutions for these problems. You can select the menu-item but somehow instead of only the selected item changing the background color (with xml attribute state-pressed ), everything in the menu is getting the color I set in itemBackground .

<android.support.design.widget.NavigationView
    android:id="@+id/nvView"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@android:color/white"
    app:headerLayout='@layout/nav_header'
    app:menu="@menu/drawer_view"
    app:itemTextColor="@drawable/drawer_item_text"
    app:itemBackground="@drawable/drawer_background_selector"
    android:fitsSystemWindows="false"/>

And here is drawer_background_selector :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/black" android:state_pressed="true" />
    <item android:drawable="@color/white"/>

</selector>

For the second problem, I want to decrease the distance between the icon and text but somehow I can't find any way to do this while using the Support Library provided by google.

Any ideas? Or do I have to go with a library like the MaterialDrawer github library. Problem with this is that I am afraid of the future in which the Design Support library might be updated but this library might not.

You can override the dimens values, and even the layout files. The only thing I'm still maybe stuck on is subheader padding).

eg you can override

    <dimen tools:override="true" name="design_navigation_icon_padding">5dp</dimen>
