设置背景图像-Android

好的，我想在我的6个按钮，页眉和页脚后面设置一个背景图像，我不希望当有人点击它或类似的东西时发生任何事情。 假设背景png图像为@drawable/background

下面是屏幕目前的样子：

这是我目前的相关代码：

dashboard_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/home_root"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <!-- Include Action Bar -->
    <include layout="@layout/actionbar_layout"/>

    <!--  Include Fragmented dashboard -->  
    <include layout="@layout/fragment_layout"/> 

    <!--  Include Footer -->
    <include layout="@layout/footer_layout"/>   

}

提前一英里谢谢各位：
