In your Activity's XML file define the listview like this ::

(Define the property in this xml file as per your requirement)

Create one Class named MyCustomListView ::

    public class MyCustomListView extends ListView
    {

       private Bitmap background;

    public MyCustomListView(Context context, AttributeSet attrs) 
    {
        super(context, attrs);
        background = BitmapFactory.decodeResource(getResources(), R.drawable.yourImageName);
    }

    @Override
    protected void dispatchDraw(Canvas canvas) 
    {
        int count = getChildCount();
        int top = count > 0 ? getChildAt(0).getTop() : 0;
        int backgroundWidth = background.getWidth();
        int backgroundHeight = background.getHeight();
        int width = getWidth();
        int height = getHeight();

        for (int y = top; y < height; y += backgroundHeight)
        {
            for (int x = 0; x < width; x += backgroundWidth)
            {
                canvas.drawBitmap(background, x, y, null);
            }
        }
        super.dispatchDraw(canvas);
    }
 }

Hope this will solve your problem :)
