Android Question What does cam.SupportedCaptureSizes return?

[MrKim]

Sigh, the little things continue to baffle me. Using CamEx2 (Camera2). I want to set the camera resolution.
I figured out how to get a list of available resolutions.

Dim Reses As List = cam.SupportedCaptureSizes

It returns values that look like like: 640x480

Perfect, I thought I will parse out the 640 and 480 and use those with:

CaptureSize.Initialize(W, H) to set the size.

Unfortunately I cannot figure out what kind of object is returned by cam.SupportedCaptureSizes.
So I can't set it to a string to parse.

Dim T as string
T=Value

returns "Error evaluating expression."

What am I missing?
Is there an easier way?

Thanks.

It returns Object CameraSize resp. a list of CameraSize objects

Public PreviewSize, CaptureSize As CameraSize
    PreviewSize.Initialize(1920, 1080)
   CaptureSize.Initialize(1920, 1080)

Public PreviewSize, CaptureSize As CameraSize
    PreviewSize.Initialize(1920, 1080)
   CaptureSize.Initialize(1920, 1080)

But that still doesn't tell me how to get the Width and Height out of it so I can use it with CaptureSize.Initialize

omg

Dim Reses As List = cam.SupportedCaptureSizes

Dim Reses As List = cam.SupportedCaptureSizes
for i=0 to Reses.size-1
  dim size as CameraSize = Reses.Get(i)
 log(size)
next

omg

Dim Reses As List = cam.SupportedCaptureSizes
for i=0 to Reses.size-1
  dim size as CameraSize = Reses.Get(i)
 log(size)
next

I still can't seem to use it. Here is my code and what I see when running.

Log says

(String) 320x240

but the H = T.Height line errors with

java.lang.ClassCastException: java.lang.String cannot be cast to android.util.Size

And as you can see T.Height Appears to be invalid.

Well, I was able to get this to run:

Sub ResList_ItemClick (Position As Int, Value As Object)
    Dim WH As String, H As Int, W As Int, T As CameraSize = Value
    Log (T)
    'T = Value =
    WH = T
    Log(WH)
    WH = WH.SubString(WH.IndexOf("(String)") + 9)
    H = WH.SubString2(1, WH.IndexOf("x"))
    W = WH.SubString(WH.IndexOf("x") + 1)
'    W = T.Width
    ToastMessageShow(Value & "  " & Position, False)
    cam.SetCaptureSize(W, H)
End Sub

But this seems kludgey. And I haven't really tested it yet to see if it does what I want.
I still want to know why the Height and Width Props of CameraSize are not available.
It is late here and I am tired and going to bed. Thanks for your help.

That's true.

DonManfred's code is correct.

You haven't posted enough code for us to say where is the object converted to string.

1. Your right, it was late and I was tired. I am putting the SupportedCaptureSizes in ResList ListView, then picking from the list. Two relevant subs are below. I set Value to T but T.Height and T.Width both say 'Error Evaluating Expression' as shown above. So I set

   WH = T

   to convert to string which gives the warning "Object Converted to string. This is probably a programming mistake." I then parse out the Height and Width, which seems to work.

Sub BtnRes_Click
    Dim X As Int
    Dim Reses As List = cam.SupportedCaptureSizes
    ResList.Visible = Not(ResList.Visible)
    ResList.Left = btnEffects.Left+btnEffects.Width + 20dip
    ResList.Top = btnCamera.Top
    ResList.BringToFront
    ResList.Clear
    For X = 0 To Reses.Size - 1
        ResList.AddSingleLine(Reses.Get(X))
    Next

End Sub

Sub ResList_ItemClick (Position As Int, Value As Object)
    Dim WH As String, H As Int, W As Int, T As CameraSize = Value
    Log (T)
    T = Value
    WH = T
    Log(WH)
    WH = WH.SubString(WH.IndexOf("(String)") + 8)
    H = WH.SubString2(1, WH.IndexOf("x"))
    W = WH.SubString(WH.IndexOf("x") + 1)
    ToastMessageShow(Value & "  " & Position, False)
    cam.SetCaptureSize(W, H)

End Sub

DOH!
My bad, I was thinking a ListView stored an object, not a string. Interesting that

ResList.AddSingleLine(Reses.Get(X))

is perfectly happy to convert CameraSize to a string. And likewise

Dim T As CameraSize = Value

was perfectly happy to set the ListView Value back to a CameraSize

Anyway here is what works:

Sub Process_Globals
    Public PWidth As Int = 1920
    Public PHeight As Int = 1080
End Sub

Sub Globals
    Private ResList As ListView
    Private Reses As List
End Sub
.
.
.
.
Sub BtnRes_Click
    Dim X As Int

    Reses.Initialize2(cam.SupportedCaptureSizes)
    ResList.Left = btnEffects.Left+btnEffects.Width + 20dip
    ResList.Top = btnCamera.Top
    ResList.BringToFront
    ResList.Clear
    For X = 0 To Reses.Size - 1
        ResList.AddSingleLine(Reses.Get(X))
    Next

End Sub

Sub ResList_ItemClick (Position As Int, Value As Object)
    Dim T As CameraSize = Reses.Get(Position)
    PWidth = T.Width
    PHeight = T.Height
    cam.SetCaptureSize(PWidth, PHeight)
End Sub

Had to make PWidth and PHeight global and use them in CamEx2 as it re-initializes when you rotate the tablet.

Thanks for your time and I apologize for missing something so obvious.
