Using XML from an Actionbar to create a Navigation Drawer menu

Question

Good morning Everybody, My first post here.

I’m with an Android project almost ready, missing just put the icons in the Menu Navigation Drawer.

I used the following tutorial to put the items in the menu.

https://thalesondev.wordpress.com/2014/09/12/utilizando-xml-para-construir-um-menu-navigation-drawer/

My code is as follows.

List<MenuItem> menuItems = createMenu();
    adapter = new ArrayAdapter<MenuItem>(
                    getActionBar().getThemedContext(),
                    R.layout.drawer_item,
                    R.id.title3,
                    menuItems);

    mDrawerListView.setAdapter(adapter);

In the tutorial it says the following: If we want an icon on each item in the menu list, just implement an Adapter with a layout that contains an image and use the icon property of the menuitem itself to specify the image of the menu item.

The above layout already contains the image.

<?xml version="1.0" encoding="utf-8"?>

<ImageView
    android:id="@+id/icones"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginTop="5dp"
    android:background="@drawable/ic_medi"
     />

<TextView
    android:id="@+id/title3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/icones"
    android:layout_toEndOf="@+id/icones"
    android:layout_toRightOf="@+id/icones"
    android:gravity="center_vertical"
    android:text="Line 1"
    android:textColor="#000"
    android:textSize="15sp" />

Only that the image in question keeps repeating itself not and altered in the same way as the text is.

The menu is as follows :

<?xml version="1.0" encoding="utf-8"?>

<item
    android:id="@+id/menu_home"
    android:icon="@drawable/ic_medi"
    android:title="@string/lblleitura"
    android:showAsAction="always" />

<item
    android:id="@+id/menu_grafic_valores"
    android:icon="@drawable/ic_graf"
    android:title="@string/lblGraficoValor"
    android:showAsAction="always"/>

<item
    android:id="@+id/menu_grafic_consumo"
    android:icon="@drawable/ic_graf"
    android:title="@string/lblGraficoConsumo"
    android:showAsAction="always"/>

  <item
    android:id="@+id/menu_grafic_consumo_medio"
    android:icon="@drawable/ic_graf"
    android:title="@string/lblGraficoMedio"
    android:showAsAction="always"/>

    <item
    android:id="@+id/menu_noti"
    android:icon="@drawable/ic_noti"
    android:title="Notícias"
    android:showAsAction="always"/>

     <item
    android:id="@+id/menu_sair"
    android:icon="@drawable/ic_sair"
    android:title="Sair"
    android:showAsAction="always"/>

Just this detail is missing to finish the project. I thank you for your help.
