Do something like this:

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

    <item
        android:id="@+id/action_settings"
        android:title="@string/action_settings"
        android:orderInCategory="100"
        app:showAsAction="always"/>

    <item
        android:id="@+id/imgAdd"
        android:title="@string/CreatePost"
        android:orderInCategory="200"
        android:icon="@android:drawable/ic_menu_add"
        app:showAsAction="always"></item>

    <item
        android:id="@+id/menu_search"
        android:title="menu_search"
        android:orderInCategory="300"
        appcompat:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always"/>

</menu>

With your menu.xml file. You need change app:showAsAction="ifRoom" to appcompat:showAsAction="always" if you want icon show. With menu item settings, you can use app:showAsAction="never" or appcompat:showAsAction="never" .

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/tools"
    xmlns:appcompat="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_settings"
        android:orderInCategory="300"
        android:title="@string/action_settings"
        appcompat:showAsAction="never"/>

    <item
        android:id="@+id/imgAdd"
        android:icon="@android:drawable/ic_menu_add"
        android:orderInCategory="200"
        android:title="@string/CreatePost"
        appcompat:showAsAction="always"></item>

    <item
        android:id="@+id/menu_search"
        android:orderInCategory="100"
        android:title="menu_search"
        appcompat:actionViewClass="android.support.v7.widget.SearchView"
        appcompat:showAsAction="always"/>

</menu>

The menu items are arranged from left to right in ascending order of integer value of android:orderInCategory (ie 100,200,300... -> left to right).
