我有一个布局的NavigationView菜单:
<item android:title="title1">
<menu>
<item
android:id="@+id/nav_tab1"
android:icon="@drawable/ic_action_nav_tab1"
android:title="test1" />
<item
android:id="@+id/nav_tab2"
android:icon="@drawable/ic_action_nav_tab2"
android:title="test2" />
</menu>
</item>
<item android:title="title2">
<menu>
<item
android:id="@+id/nav_settings"
android:icon="@drawable/ic_action_settings"
android:title="test3" />
</menu>
</item>
how can remove the line divider from menu?
