问题描述

我试图用NavigationView实施NavigationDrawer。我已经通过设置组ID在菜单中添加的分隔符。但是我看不到的分隔符。我想这是因为分隔符的颜色是一样的背景。所以我想改变分离颜色。不过,我觉得没有办法改变它。谁能帮我?

在截图中,似乎有历史之间的空间分隔设置,但你不能看到吧。

解决方案

刚申请下style.xml行

 <项目名称=机器人:listDivider> your_color< /项目>
 

下面就是信息,你的知识...... 如果你看过设计支持库。他们使用的是以下布局NavigationView seprator ..

 <的FrameLayout的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
             机器人:layout_width =match_parent
             机器人:layout_height =WRAP_CONTENT>

    <查看机器人:layout_width =match_parent
          机器人:layout_height =1DP
          机器人:背景=机器人:ATTR / listDivider/>

< /的FrameLayout>
 

在这里,你可以看到机器人:背景=机器人:ATTR / listDivider .. 因此,享受... 这里是我的输出,我改变颜色,holo_blue

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.

        app:menu="@menu/drawer"/>
</android.support.v4.widget.DrawerLayout>

            android:title="@string/navdrawer_item_about"/>
    </group>
</menu>

解决方案

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
