I created this class, but Marquee in the labels doesn't work. It works when slide the status bar, but I don't know why, I guess 'cause the panel lost the focus:

Sub SetEllipsize(TextView As Label, Mode As String)
    Dim r As Reflector
    r.Target = TextView
    r.RunMethod2("setSingleLine", True, "java.lang.boolean")
    r.RunMethod2("setEllipsize", Mode, "android.text.TextUtils$TruncateAt")
    r.RunMethod2("setSelected", True, "java.lang.boolean")
End Sub

I call this class in the follow code:

B4X:
Sub ListaWiFi_ItemClick(Index As Int, Value As Object)
   
    wifi = Operaciones.listWifiUnique.Get(Index)
   
    Dim msg As cMsgBox
    msg.Initialize(Activity, wifi.Get("SSID"), Activity.Width * 0.90, Activity.Height * 0.90, Null)
   
    For i = 0 To wifi.Size-1
        Dim key As String : key = wifi.GetKeyAt(i)
        If key.EqualsIgnoreCase("key_pass") = False AND key.EqualsIgnoreCase("finpass") = False AND key.EqualsIgnoreCase("key_encr") = False AND key.EqualsIgnoreCase("key_thumb") = False Then msg.ShowMessage(wifi.GetKeyAt(i), wifi.GetValueAt(i))
    Next
   
End Sub

Why is that?
Thanks

marquee in the normal Android TextView only works if the view has the focus. This is a limitation of the standard TextView and can only be changed if you create a library with an extended version of the TextView object.

Solution how to extend the normal TextView is explained here.

This is a little project where I'm using marquees, you should click in item and a dialog appear, but marquee doesn't work, you should slide down the status bar and then marquee works.

Thanks

I solve this making the menu of the application appears and disappears.

I know it's a bad solution, but it worked.
