Try it this way:

' 1. create columns ot listView!!
' 2. then loop through the row and columns to datatable:
' NOTE: make sure that the number of columns in listView IS equal to columns to datatable!!

For i As Integer = 0 To ds.Tables(0).Rows.Count - 1
    Dim lvi As New ListViewItem()
    For j As Integer = 0 To ds.Tables(0).Rows(i).ItemArray.Length - 1
        lvi.SubItems.Add(ds.Tables(0).Rows(i)(j).ToString())
    Next
    listView1.Items.Add(lvi)
Next

        conn = New OleDbConnection("Provider = Microsoft.ace.oledb.12.0; data source=|DataDirectory|\AutomatedLibrarySystem.accdb")
        conn.Open()
        str = "select * from BookInfo"
        com = New OleDbCommand(str, conn)
        oledbda = New OleDbDataAdapter(com)
        ds = New DataSet
        oledbda.Fill(ds, "BookInfo")
        ListView1.Clear()
        dt = ds.Tables("BookInfo")

        For i As Integer = 0 To ds.Tables(0).Rows.Count - 1
            Dim lvi As New ListViewItem()
            For j As Integer = 0 To ds.Tables(0).Rows(i).ItemArray.Length - 1
                lvi.SubItems.Add(ds.Tables(0).Rows(i)(j).ToString())
            Next
            ListView1.Items.Add(lvi)
        Next

        conn.Close()
    End Sub

like this?
I'll sure that the columns in listview is equaal to the columns in datatable
it doesn't work
:(

Sure it doesnt.
Why you called listView1.Clear() method? This clears all the data and columns.
Do only:

listView1.Items.Clear()
