I am using NavigationView control of android to create sliding drawer. All is fine except spacing between Menu Items in navigation view as shown in image.
Navigationview
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
app:headerLayout="@layout/homescreen_header"
app:menu="@menu/homescreen_nav_drawer"
app:itemIconTint="@color/green"
app:itemTextColor="@color/White"
app:theme="@style/NavigationView"
app:itemBackground="@color/nav_item_bg"
android:background="@color/nav_item_bg"
/>
<style name="NavigationView" >
<item name="android:listDivider">@android:color/black</item>
</style>
create a style with
<style name="NavigationViewStyle">
<item name="android:listPreferredItemHeightSmall">25dp</item><!-- menu item height-->
</style>
and apply this style to NavigationView
app:theme="@style/NavigationViewStyle"
