And here is my class

}
#Override

if (view == null) {

}
return view;
}
private static class DrawerItemHolder {
TextView ItemName, title;
MLRoundedImageView icon;
LinearLayout headerLayout, itemLayout;
}
}
And my view.xml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="fill_parent" >

<TextView

<View

</LinearLayout>
<LinearLayout

</LinearLayout>
<View

android:background="#DADADC"
></View>
</LinearLayout>
</RelativeLayout>
