xmlns:android="http://schemas.android.com/apk/res/android">

<item android:title="صفحه اصلی"
      android:id="@+id/menuitem1"

    android:id="@+id/navigation_view"
    android:layout_width="250dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:menu="@menu/navigation_menu"
    app:headerLayout="@layout/navigation_header"
    tools:layout_editor_absoluteY="8dp"
    tools:layout_editor_absoluteX="0dp">
</android.support.design.widget.NavigationView>

Solution

Here first get a Locale and set in preference and create layout-ar folder in drawable folder and create a four same file of one layout and put two file in simple layout and rest two put in layout-ar folder mentioned below.

Adapter of nevigation drawer:-

 mainSettinglanguage = AppPreference.getStringPref(context, AppPreference.PREF_MAIN_SETTING_LANGUAGE, AppPreference.PREF_KEY.MAIN_SETTING_LANGUAGE);
        if (mainSettinglanguage != null && mainSettinglanguage.equals("ar")) {
            view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.section_list_item_ar, viewGroup, false);
        } else {
            view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.section_list_item, viewGroup, false);
        }
