How to fix "Cancel & Voice button on left" in RTL Search Bar

I developed an RTL android app. I implemented an Actionbar that contains a Search bar. but the Cancel and Voice button are on the right of the text.

As you know, the cancel and voice button must be on the left of the text in RTL.

Notice:

• I've added the layoutDirection & textDirection for all of AppBarLayout, Toolbar & SearchView.

• I've added the android:supportsRtl="true" at Manifest too.

• I've set Gravity to End.

Layouts:

app_bar_home.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layoutDirection="rtl"
    tools:context=".home.Home">

    <android.support.design.widget.AppBarLayout
        android:layoutDirection="rtl"
        android:textDirection="rtl"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:layoutDirection="rtl"
            android:textDirection="rtl"
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_home" />

</android.support.design.widget.CoordinatorLayout>

menu_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/menu_search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="@string/search_hint"
        app:showAsAction="always|collapseActionView"
        app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>

searchable.xml:

<?xml version="1.0" encoding="utf-8"?>
<searchable
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint"/>

Manifest:

<activity
    android:name=".home.Home"
    android:label="@string/app_name"
    android:theme="@style/AppTheme.NoActionBar">
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
    </intent-filter>
    <meta-data
        android:name="android.app.searchable"
        android:resource="@xml/searchable" />
</activity>

So, How can I change the position of SearchBar Buttons to the left?
