How to create a simple divider in the new NavigationView?
Solution 1:
All you need to do is define a group
with an unique ID, I have checked the implementation if group has different id's it will create a divider.
Example menu, creating the separator:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<group android:id="@+id/grp1" android:checkableBehavior="single" >
<item
android:id="@+id/navigation_item_1"
android:checked="true"
android:icon="@drawable/ic_home"
android:title="@string/navigation_item_1" />
</group>
<group android:id="@+id/grp2" android:checkableBehavior="single" >
<item
android:id="@+id/navigation_item_2"
android:icon="@drawable/ic_home"
android:title="@string/navigation_item_2" />
</group>
</menu>
Solution 2:
create a drawable drawer_item_bg.xml like this,
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<solid android:color="#F4F4F4" />
</shape>
</item>
<item android:top="-2dp" android:right="-2dp" android:left="-2dp">
<shape>
<solid android:color="@android:color/transparent" />
<stroke
android:width="1dp"
android:color="#EAEAEA" />
</shape>
<!--
android:dashGap="10px"
android:dashWidth="10px"
-->
</item>
</layer-list>
and add it to NavigationView as app:itemBackground="@drawable/drawer_item_bg"
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#F4F4F4"
android:layout_gravity="start"
android:fitsSystemWindows="false"
app:menu="@menu/activity_main_drawer"
app:itemBackground="@drawable/drawer_item_bg"/>
and here we go...
