用listView1_DrawItem，将文字写到图片上.
参考：

private void listView1_DrawItem(object sender, DrawListViewItemEventArgs e)
{

e.Graphics.DrawImage(e.Item.ImageList.Images[e.Item.ImageIndex], e.Bounds);
e.Graphics.DrawString(e.Item.Text,e.Item.Font,new SolidBrush(e.Item.ForeColor),new Point(e.Bounds.X+5, e.Bounds.Y+50));
}

设置： this.listView1.OwnerDraw = true;

我要把图片和文字，整一块都是同颜色的，因为显示的Items比较多。

重绘背景色或者自定义这样的控件
参考如下代码



private void callListDataGridView_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)

    {

        if ((e.ColumnIndex == 0) && (e.RowIndex >= 0))

        {

            // Draw Merged Cell

            Graphics g = e.Graphics;

            bool selected = ((e.State & DataGridViewElementStates.Selected) == DataGridViewElementStates.Selected);

            Color fcolor = (selected ? e.CellStyle.SelectionForeColor : e.CellStyle.ForeColor);

            Color bcolor = (selected ? e.CellStyle.SelectionBackColor : e.CellStyle.BackColor);

            Font newfont = e.CellStyle.Font;



            newfont = new Font(newfont, FontStyle.Bold);



            // Get size information

            string cust = this.callListDataGridView.Rows[e.RowIndex].Cells[0].Value.ToString();

            string subject = this.callListDataGridView.Rows[e.RowIndex].Cells[1].Value.ToString();

            Size newSize = TextRenderer.MeasureText(e.Graphics, cust, newfont);



            // Calculate where to draw the content

            int x = e.CellBounds.Left + e.CellStyle.Padding.Left;

            int y = e.CellBounds.Top + e.CellStyle.Padding.Top;

            int width = e.CellBounds.Width - (e.CellStyle.Padding.Left + e.CellStyle.Padding.Right);

            int height = newSize.Height + (e.CellStyle.Padding.Top + e.CellStyle.Padding.Bottom);



            // Draw background

            g.FillRectangle(new SolidBrush(bcolor), e.CellBounds);



            // Draw first line

            TextRenderer.DrawText(e.Graphics, cust, newfont, new Rectangle(x, y, width, height), fcolor, TextFormatFlags.PreserveGraphicsClipping | TextFormatFlags.EndEllipsis);



            // Use grey for second line if not selected

            if (!selected)

            {

                fcolor = Color.Gray;

            }



            // Reset font and y location

            newfont = e.CellStyle.Font;

            y = y + height - 2;



            TextRenderer.DrawText(e.Graphics, subject, newfont, new Rectangle(x, y, width, height), fcolor, TextFormatFlags.PreserveGraphicsClipping | TextFormatFlags.EndEllipsis);



            e.Handled = true;

        }

    }
