change the icons direction for menu items(DrawerLayout) Android?

Question

How I can change item direction menu?

I need to change the icons direction to RTL instead of LTR, I use Gravity and Layout_Gravity but don't work .

What can I do ? Below is my XML :

menu_start.xml :

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

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/circle"
            android:title="@string/Search" />
        <item
            android:id="@+id/nav_example_item_1"
            android:icon="@drawable/circle"
            android:title="Example Item #1" />
    </group>

    <item android:title="Sub items">
        <menu>
            <item
                android:id="@+id/nav_example_sub_item_1"
                android:title="Example Sub Item #1" />
        </menu>
    </item>

</menu>

activity_start.xml :

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:orientation="vertical">

            <!-- We use a Toolbar so that our drawer can be displayed

Answer 1

Try this : first add { android:supportsRtl="true" } to AndroidManifest.xml :

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:supportsRtl="true" >

</application>

then in your activity_start.xml add these two lines to DrawerLayout :

android:layoutDirection="rtl"
android:textDirection="anyRtl"
