Set an image to whole of custom ListView

I'm making a messaging app. It works fine. In the conversation activity, I have a custom List View that inflates an xml layout as shown below:

but I want to put an image instead of green background like this:

this is my current xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#79ff93">

<ListView
    android:id="@+id/listMessages"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/divider"
    android:divider="@null"
    android:dividerHeight="0dp"
    android:padding="0dip"
    android:stackFromBottom="true"
    android:transcriptMode="alwaysScroll"
    tools:listitem="@layout/message_left" />

<RelativeLayout
    android:id="@+id/divider"
    android:layout_width="fill_parent"
    android:layout_height="1dip"
    android:layout_above="@+id/relSendMessage"
    android:background="@color/off_white" />

<RelativeLayout
    android:id="@+id/relSendMessage"
    android:layout_width="wrap_content"
    android:layout_height="48dp"
    android:layout_alignParentBottom="true"
    android:background="@android:color/white"
    android:paddingLeft="10dp">


    <EditText
        android:id="@+id/messageBodyField"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignBottom="@+id/sendButton"
        android:layout_alignTop="@+id/sendButton"
        android:layout_marginBottom="-4dp"
        android:layout_marginRight="10dp"
        android:layout_toLeftOf="@+id/sendButton"
        android:background="@android:color/white"
        android:hint="@string/message_hint"
        android:textColor="@android:color/black"
        android:textSize="14sp" />

    <Button
        android:id="@+id/sendButton"
        android:layout_width="72dp"
        android:layout_height="match_parent"
        android:layout_alignParentRight="true"
        android:layout_margin="4dp"
        android:background="@drawable/button_send" />
</RelativeLayout>

Thank you guys.

in the layout change the attribute for the background which is ListView in this case

to this 

android:background="@drawable/index_one"

you should see things something like this

Placing an ImageView above your ListView in your XML would do the trick.

You can use a drawable as your background. Any view can get a drawable background. For your case, perhaps it would be better to put it on the ListView and remove the android:background tag from the base view.

    <ListView 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/chat_bg">

chat_bg can be either a png or an xml in your drawable folder. You need to consider different aspect ratios and screen sizes if you choose to use an image.

Just put your ListView inside RelativeLayout with height match parrent, and set background for this layout desierd image.

....
<RelativeLayout
    android:id="@+id/container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_above="@+id/divider"
    android:background="@drawable/your_image" >

    <ListView
        android:id="@+id/listMessages"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="@null"
        android:dividerHeight="0dp"
        android:padding="0dip"
        android:stackFromBottom="true"
        android:transcriptMode="alwaysScroll"
        tools:listitem="@layout/message_left" />

</RelativeLayout>
....
