Android Question What type of data have I inside my map?

[josejad]

Hi all:

I have a jRDC2 class, with this sub to return a map with 3 keys: "Correcto" (Boolean), "Data" (DBResult), "Message" (string)

Spoiler: jrdc.GetRecord Sub

Public Sub GetRecord (Command As String, parameters() As String) As ResumableSub
    Dim Respuesta As Map
    Respuesta.Initialize
    Dim req As DBRequestManager = CreateRequest
    Dim cmd As DBCommand = CreateCommand(Command, parameters)
    Wait For (req.ExecuteQuery(cmd, 0, Null)) JobDone(j As HttpJob)
    Respuesta.Put("Correcto", j.Success)
    If j.Success Then
        req.HandleJobAsync(j, "req")
        Wait For (req) req_Result(Res As DBResult)
        'work with result
        'req.PrintTable(res)
        Respuesta.Put("Datos",Res)
        Respuesta.Put("Mensaje","Se han leído correctamente los datos")
    Else
        Log("ERROR: " & j.ErrorMessage)
        Respuesta.Put("Mensaje","No han leído correctamente los datos, inténtelo más tarde. Error: " & j.ErrorMessage)
    End If
    j.Release

    Return Respuesta
End Sub

So "Respuesta" is a map, and Respuesta.Get("Datos") is a DBResult type: Type DBResult (Tag As Object, Columns As Map, Rows As List)

Well, I have the sub where I receive the data

Spoiler: Getting the data

Sub PopulatePartes (Month As Long)
    .....
    jRDC.Initialize
   .....
    B4XLoadingIndicator1.Show
    Wait For(jRDC.GetRecord("selectParteTrabajo", Parametros)) Complete (Respuesta As Map)
       .....
        rs = Respuesta.Get("Datos")
       ...
        Dim Datos() As Object
        mapResultados.Initialize  'Global map Variable
        If rs.Rows.Size > 0 Then
            Datos = rs.Rows.Get(0)
                .....
                listaPartesDia.Add(Datos)
                mapResultados.Put(TodayDate, listaPartesDia)
               .....
            Log("Resultados: " & mapResultados)   '<----See logs below
        End If
        ....
    For i = 1 To DateUtils.NumberOfDaysInMonth(DateTime.GetMonth(Month), DateTime.GetYear(Month))  'From day 1 to 31...
        ....
        Dim p As B4XView = CreateItem(color, DiaActual, 300dip)
        clvPartesTrabajo.Add(p, expandable.CreateValue(p, DiaActual))
      ....
    Next
    B4XLoadingIndicator1.Hide
End Sub

So, in mapResultados I have a key (TodayDate) with a List of arrays... (or and array of objects I think). I mean, I have every month's day, with none, one, o more items
The log of Log("Resultados: " & mapResultados)

Resultados: (MyMap) {04/03/2020=[[Ljava.lang.Object;@4ef5260, [Ljava.lang.Object;@b3f8319], 02/03/2020=[[Ljava.lang.Object;@6804c92], 03/03/2020=[[Ljava.lang.Object;@6e14663], 05/03/2020=[[Ljava.lang.Object;@2529fde], 06/03/2020=[[Ljava.lang.Object;@d97e5bf]}

My problem is go through the [[Ljava.lang.Object;@4ef5260, [Ljava.lang.Object;@b3f8319] data.

I want to get this data in this sub

Sub CreateItem(clr As Int, Today As String, ExpandedHeight As Int) As B4XView
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, clvPartesTrabajo.AsView.Width, ExpandedHeight)
    p.LoadLayout("Item")
    ......
    'Add a panel for every job the day has
    Dim ListaDatos As List
    ListaDatos = mapResultados.Get(DateTime.Date(Today))  
    If ListaDatos.IsInitialized Then 'If we have jobs for this day
        Dim parte As List
        For i = 0 To ListaDatos.Size-1
            parte = ListaDatos.get(i)
            ...
            lbProyecto.Text = "PROYECTO: " & parte.Get(0)
            ...
        Next
    End If
    Return p
End Sub

The error I get (I've tried several types for "parte", list, array of list, array of strings...)

java.lang.ClassCastException: java.lang.Object[] cannot be cast to java.util.List

Probably the answer is very easy but I'm blocked today...

Based on the error message it is an array of objects.

The code should be:

Dim ListaDatos() As Object = mapResultados.Get(DateTime.Date(Today))
