Android Question show different name of value in spinner keeping value

hi, i have created an app to turn off a relay.
I have a problem, I need a spinner to be able to put a display name and run a different one.
I explain, I have two activities, one is called settings and the other is main.
In configuration I put the ip addresses to which I execute a command. The first two IP addresses are the ones that I can select later in the spinner, to execute the command to one or the other.
The problem is that the ip addresses are very similar and there are times that I make a mistake when selecting them, I need the name shown in the spinner to be a different one than the value it actually has

Settings:


Main:




Main Spinner:





I need a text to be displayed instead of that ip (such as my name), but the value should really be the ip

Thanks

Using a map:


i.e.:
B4X: 
Dim MapRelays As Map
MapRelay.Initialize 
MapRelay.Put("Relay1", "12.26.0.206")
MapRelay.Put("Relay2", "12.16.0.206")

For Each relay As String In MapRelays.Keys
  Log(k)
 'Populate your Spinner
Spinner1.Add(relay) 
Next

After that, when you get the SelectedItem, you can search for it in the map, and get the IP

With B4XPreferencesDialog, see the examples and videos. You can use a PreferencesDialog better than a Spinner using the "options" type.

Try it and ask any question you have.

@José J. Aguilar
the point is that the ip addresses may vary depending on what you put in the settings.
In the example you have defined some IPs that are always the same

in spanish:
te lo pongo en español pq he visto que eres de sevilla
el tema es que las direcciones ip pueden variar dependiendo de lo que ponga en el archivo settings.
en el ejemplo has definido unas ip que siempre son las mismas

Ok, so it depends on the way you save the ip addresses in the config activity: a file, sqlite, kvs?

Post in english here, there’s a specific spanish forum.

Si señor, ando por Sevilla. De dónde eres tú? Intenta también no preguntar a alguien en concreto (en este caso a mi) para que así otros se sientan libres de contestarte.

saludos,

a file, this is my settings file.
I dont know if its the best code but it work

Settings: 
Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim EditText1 As EditText
    Dim EditText2 As EditText
    Dim EditText3 As EditText
    Dim EditText4 As EditText
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Settings")
    EditText1.Text = Main.HostName1  
    EditText2.Text = Main.HostName2
    EditText3.Text = Main.HostName3
    EditText4.Text = Main.HostName4
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub Button2_Click
    Activity.Finish
End Sub

Sub Button1_Click
    Dim s As List

    Main.HostName1 = EditText1.Text
    Main.HostName2 = EditText2.Text
    Main.HostName3 = EditText3.Text
    Main.HostName4 = EditText4.Text

    s.Initialize
    s.Add(Main.HostName1)

One way of doing it could be with the map as in my previous post. Just add the hostnames to the map after your get them.

i.e., add in the line #56
B4X: 
For i = 0 To s.Size - 1
   MapRelay.Put("Hostname" & i , s.Get(i))
Next

In this code, appear me an error that say something about k, i think something like k variable or something...
In line Log(k)

B4X: 
Dim MapRelays As Map
MapRelay.Initialize
MapRelay.Put("Relay1", "12.26.0.206")
MapRelay.Put("Relay2", "12.16.0.206")

For Each relay As String In MapRelays.Keys
  Log(k)
 'Populate your Spinner
Spinner1.Add(relay)
Next

I can't get it to work...
At the moment I have this, I do not know if I have done it correctly, it is a function that I had never used before and I do not know how to use

ok i think we have something but not much.
I managed to make the map and it works correctly, but there is a problem
now when pressing the button to send the command to the ip, it does not work. I think the error is that the ip is taken from the file saved in settings
i think the error is from the line #207 to the end, where it says "CharAt (0)"

Sorry, I can't help with that kind of questions, I haven't worked with streams or bytes.
If you write the logs of what you get or what you're trying to send, maybe someone else can help.

Just one thing:
B4X: 
sock.Connect(Spinner1.SelectedItem, 6722, 10000)

If I'm not wrong, Spinner1.SelectedItem will be "Cáceres" or "Badajoz", if you want to send the IP, don't you should send?:
B4X: 
sock.Connect(MapHosts.Get(Spinner1.SelectedItem), 6722, 10000)

ok, thats perfect, works so good. but now comes the second part

Since I have the app, an error appears from time to time when the mobile screen has been off with the app active, I attach a photo of the error. (photo with black background)
also I do not know for what reason I received another different error when I edited the ip from settings (photo with white background)





Thank you very much to all of you for the help, especially to @José J. Aguilar

This error is unrelated, you should start a new post. Having said that, you should move your socket code to the Starter service (or a custom service/class managed by the
starter service).
