如何在NavigationView中更改分隔符颜色？

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?

我正在尝试使用NavigationView来实现NavigationDrawer。我通过在菜单中设置组ID添加了分隔符。但是我看不到分隔符。我想这是因为分隔符颜色与背景相同。所以我想更改分隔符颜色。但我发现无法改变它。谁能帮我？

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

在屏幕截图中，它似乎在历史记录和设置之间有分隔空间，但您无法看到它。

just apply following line on style.xml

只需在style.xml上应用以下行

<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..

以下是您的知识信息...如果您已经看过设计支持库..他们使用以下布局为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

在这里，你可以看到android：background =“？android：attr / listDivider”..所以享受...这里是我的输出，我改变颜色为holo_blue

Here is best and easy way while using menu as view

使用菜单作为视图时，这是最好和最简单的方法

<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

ThemeToolbar.NavigatinoView

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

yas you have to add blank header as separator.

你必须添加空白标题作为分隔符。

<!-- 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.

textColorPrimary更改标题的颜色。

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

在styles.xml中创建一个样式。在android：listDivider中输入您的首选颜色

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

Reference the style as the theme of your navigation view:

将样式引用为导航视图的主题：

   <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!

最后，确保菜单中的组具有唯一ID。如果您的组没有id属性，这将不起作用！

<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>
