title: Android right to left NavigationDrawer menu items aren't RTL
body: <p>I need to align navigation menu items to the right.
  I read many articles and questions and answers but i couldn't find what's wrong in my project.
  This is my xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v4.widget.DrawerLayout 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"
  android:id="@+id/drawer_layout"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:fitsSystemWindows="true"
  tools:openDrawer="right"&gt;
  
  &lt;include
      layout="@layout/content_activity_home"
      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="right"
      android:fitsSystemWindows="true"
      app:headerLayout="@layout/nav_header_activity_home"
      app:menu="@menu/activity_home_drawer" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>This is <strong>activity_home_drawer.xml</strong>:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;group android:checkableBehavior="single"&gt;
      &lt;item
          android:id="@+id/menu_account"
          android:icon="@drawable/ic_profile"
          android:title="حساب کاربری" /&gt;
      &lt;item
          android:id="@+id/menu_logout"
          android:icon="@drawable/ic_sign_out"
          android:title="خروج از حساب" /&gt;
  &lt;/group&gt;
  </code></pre>
  
  <p></p>
  
  <p>I can make drawer itself to open from right but elements of NavigationView still remain left to right. You can see the result here:</p>

  <p>As you see menu items aren't right to left. How to make them rtl?</p>
