Navigation Drawer Menu Scroll Effect
<p>I'm using NavigationView in DrawerLayout for my app's navigation menu here's the xml:  </p>

<pre><code>&lt;android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawerLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"&gt;

    &lt;include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" /&gt;

    &lt;android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        android:foreground="?android:attr/selectableItemBackground"
        android:theme="@style/NavigationDrawerStyle"
        app:headerLayout="@layout/nav_header_main"
        app:itemIconTint="@color/textColor"
        app:itemTextColor="@color/textColor"
        app:menu="@menu/activity_main_drawer" /&gt;
    &lt;/android.support.v4.widget.DrawerLayout&gt;
</code></pre>

<p>The problem: I don't even have enough items to scroll but I'm seeing this effect while trying to scroll, I want to disable this effect, thank you.<br>

<p><strong>Update</strong></p>

<p>trying both:</p>

<pre><code>android:overScrollMode "never" in NavigationView
</code></pre>

<p>and</p>

<pre><code>navigationView.setVerticalFadingEdgeEnabled(false);
</code></pre>

<p>didn't work.</p>

<p>I'm calling following method in <code>onCreate()</code> :</p>

<pre><code>public void setupDrawerLayout() {
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolBar, R.string.drawer_open, R.string.drawer_close);
    drawerLayout.setDrawerListener(drawerToggle);
    drawerToggle.syncState();

    navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}
</code></pre>
