Android – Custom open drawer view – Photoshop

So, I did this in photoshop:

Is a navigationview:

But for some reason in android I get this:

My questions:

1: How can I change the title color of the menu?

This is my menu.xml:

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

    <group android:checkableBehavior="single" android:id="@+id/grp1">
        <item android:title="LOREM IPSUM" android:id="@+id/menu_1">
            <menu>
                <item
                    android:id="@+id/nav_camera"
                    android:icon="@drawable/sharkred"
                    android:title="LOREM IPSUM" />
                <item
                    android:id="@+id/nav_gallery"
                    android:icon="@drawable/sharkblue"
                    android:title="LOREM IPSUM" />
                <item
                    android:id="@+id/nav_slideshow"
                    android:icon="@drawable/sharkpink"
                    android:title="LOREM IPSUM" />
            </menu>
        </item>

    </group>

    <item android:title="LOREM IPSUM" android:id="@+id/action_divider"
        >
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/sharkyellow"
                android:title="LOREM IPSUM" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/sharkgreen"
                android:title="LOREM IPSUM" />
        </menu>
    </item>

    <item android:title="LOREM IPSUM"
        >
        <menu>
            <item
                android:id="@+id/nav_share2"
                android:icon="@drawable/sharkgrey"
                android:title="LOREM IPSUM" />
        </menu>
    </item>

</menu>

2: How can I add a line separator below of the items and not the title? Is not a full line.
3: I added my icons to the menu.xml but the images are black.
