How can I change separator color in NavigationView?


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.

Solution

  • 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 enter image description here
