How can I change separator color in NavigationView?

Question

I'm trying to use NavigationView to implement NavigationDrawer. I have added the separator by setting group id in menu. However I can't see the separator. I guess it is because the separator color is same as the background. So I want to change the separator color. But I find no way to change it. Can anyone help me?

In screenshot, it seems have a room for separator between History and Settings, but you can't see it.

Answer 1

just apply following line on style.xml

<item name="android:listDivider">your_color</item>

The below is just information for your knowledge ... If you have seen design support library .. they are using following layout for NavigationView seprator..

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="wrap_content">

    <View android:layout_width="match_parent"
          android:layout_height="1dp"
          android:background="?android:attr/listDivider"/>

</FrameLayout>

here, you can see android:background="?android:attr/listDivider" .. So enjoy ... and here is my output that i change color to holo_blue

Any way of doing it programatically? – Cuba

@Cuba No unfortunately there is no option for doing it programatically ... may be in future library it wil come .. – Lieb

where to apply the below line <item name="android:listDivider">your_color</item> – Scratchy

to your main style for eg. In Apptheme – Radioactive

doesnt work for me, moreover the attributte doesnt accept color in hex format only the @color resource which is strange – Primm

@Lieb What if I want a divider between grouped items? – Devon

@Devon follow this answer https://mcmap.net/q/273078/-android-navigationview-menu-group-divider-duplicate and see comment of Yassen Ahmed who want something like you and solved it. – Lieb

@Lieb how to change divider color programatically. i tried but idid not get anysolution for that .Thanks in advance..:) – Mascot

Is it possible to change divider color dynamically. Ofcourse yes but i didn't get any way for that :) – Mascot

I tried it before a year. But i didn't find it. And for now i am away from my machine for 5 days. I can try after 5 days. – Lieb

where i have to add frame layout i have added style but its not wokring can please suggest me @Lieb – Commutative

Is there any way to adjust margin/padding on the divider? – Conjunctiva

this is bad solution. If you want to set it only for navigation view, than it doesnt work at all, if you set it for activity - it works, but it changes divider color in whole activity, for each your list. – Unapproachable

@Unapproachable have you applied the style in which you mention the color ...? – Lieb

Of course I did, but it just doesnt work :) You can ONLY change dividerColor for whole activity, this way it works (but its not good solution). But making custom style, and aplying it to NavigationView only, it doesnt work – Unapproachable

Making custom style should also work... I don't know what's the issue with your code... Make sure you are not missing something.. I can only help when i can see your code ... – Lieb

Here is best and easy way while using menu as view

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    android:theme="@style/ThemeToolbar.NavigationView"
    app:itemTextColor="@color/white"
    app:itemIconTint="@color/white"
    app:headerLayout="@layout/activity_home_nav_header"
    app:menu="@menu/activity_home_drawer" />

ThemeToolbar.NavigatinoView

 <style name="ThemeToolbar.NavigationView" >
    <item name="android:listDivider">@color/white</item>
    <item name="android:textColorSecondary">@color/white</item>
</style>

Anthologize

What is the ThemeToolbar.? – Aitch

It is any name of app theme, Here it is added just to associated NavigationView with ThemeToolbar so written as ThemeToolbar.NavigationView. NavigationView can be written as itself. – Anthologize

just add the style in your values file, styles.xml if this is the name you have given @MhanazSyed, or you can share your code if you still help on this – Anthologize

Do you need any help on this @Unapproachable – Anthologize

Answer 3

Create a style in your styles.xml. Enter your preferred color in the android:listDivider

<style name="NavigationView"  parent="Base.Theme.AppCompat">
    <item name="android:listDivider">@color/text_lightgray</item>
</style>

Reference the style as the theme of your navigation view:

   <android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="false"
    android:theme="@style/NavigationView"
    app:headerLayout="@layout/nav_header"
    app:menu="@menu/drawer_view"
    app:itemTextColor="@color/text_white"/>

Lastly, make sure that the groups inside your menu have unique ids. If your groups do not have the id attribute, this won't work!

<group android:checkableBehavior="single"
    android:id="@+id/group1">
    <item
        android:id="@+id/item1"
        android:title="@string/item1" />
</group>
<group android:checkableBehavior="single"
    android:id="@+id/group2">

    <item
        android:id="@+id/item2"
        android:title="@string/item2" />

</group>

Answer 5

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/menu_text_color</item>
    <item name="android:textColorSecondary">@color/menu_text_color</item>
</style>

textColorPrimary changes the color of the header.

Answer 6

Divider Color Is Changed

STEP 1:

Create list_divider.xml file in your drawable folder.

copy and paste the following lines into your list_divider.xml.

 <?xml version="1.0" encoding="utf-8"?> 
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="@dimen/_16sdp"
android:insetRight="@dimen/_16sdp">
<shape>
    <solid android:color="#FFFFFF" />
    <size android:height="2dp" />
</shape>
</inset> 

STEP 2:

Add this line to your Main Theme ( Theme Mentioned in your AndroidManifest.xml file)

 <item name="android:listDivider">@drawable/list_divider</item>

For Example

<style 
     name="MyMaterialTheme.Base" 
     parent="Theme.AppCompat.Light.NoActionBar">

    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item> 
    <item name="android:listDivider">@drawable/list_divider</item>
    <item name="android:listDivider">@drawable/list_divider</item>

STEP 3: No Change required in NavigationView for divider Color

 <com.google.android.material.navigation.NavigationView
        android:id="@+id/navigationView"
        android:layout_width="@dimen/nav_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="?attr/colorPrimary"
        app:headerLayout="@layout/header_navigation_drawer"
        app:itemIconTint="?attr/nav_drawer_icon_color"
        app:itemTextColor="?attr/nav_text_color"
        app:menu="@menu/navigation_drawer_list_menu"
        tools:ignore="MissingConstraints" />
