item click custom listview basic4android

Question

I made a customlistview in b4a but I can not fix the click event.

I want when button clicks image to pause and other buttons image to play when click image button is changed but other button image not change.

my code load

Sub load
For i = 0 To cur.RowCount-1
cur.Position=i
Dim p As Panel
play.Text = Chr(0xE037)
p.Initialize("p")
sco.Panel.AddView(p,1%x,top,98%x,500dip)
p.LoadLayout("layload")
play.Tag = cur.GetInt("id")
play.Typeface = awf
text.Text = cur.GetString("text")
top = top + 60dip + 2%x
Next
sco.Panel.Height = top + 10dip
End Sub

and code play

Sub play_Click
tim.Enabled = True
Dim lml As Label
lml.Initialize("lml")
lml = Sender
Dim curbv As Cursor
curbv = sql.ExecQuery("SELECT * FROM tab1 ")
curbv.Position = lml.Tag - 1
sec = curbv.Position
meda.Load(File.DirAssets,curbv.GetString("mp"))
kl(lml)
End Sub

and my code for change icon

Sub kl( ln As Label) 
If ln.Text = Chr(0xE037) Then
ln.Text = Chr(0xE047)
meda.Play
load
Else If ln.Text = Chr(0xE047) Then
ln.Text = Chr(0xE037)
meda.Stop
End If
Sleep(100)
play.Text = Chr(0xE037)
End Sub
