Android Question screenshot and dirInternal

[settedicinque]

Hi all, I need your help. Is it possible let the users make a screenshot and save it in dirInternal? I tried using the code in the beginner's guide but it didin't work. I don't have any error messages, but on the phone doesn't appear any screenshot.

You can make screenshots of your activities and store them in File.DirInternal. Can you post the relevant code that is not working?

Private Obj1, Obj2 As Reflector
Private bmp As Bitmap
Private c As Canvas
Private now As Long
Private dt As String
DateTime.DateFormat = "yyMMddHHmmss"
now = DateTime.now
dt = DateTime.Date(now) ' e.g.: "110812150355" is Aug.12, 2011, 3:03:55 p.m.
Obj1.Target = Obj1.GetActivityBA
Obj1.Target = ScrollView1.Panel
bmp.InitializeMutable(Activity.Width, Activity.Height)
c.Initialize2(bmp)
Private args(1) As Object
Private types(1) As String
Obj2.Target = c
Obj2.Target = Obj2.GetField("canvas")
args(0) = Obj2.Target
types(0) = "android.graphics.Canvas"
Obj1.RunMethod4("draw", args, types)
Private Out As OutputStream
Out = File.OpenOutput(File.DirInternal, dt & ".png", False)
bmp.WriteToStream(Out, 100, "PNG")
Out.Close


this is the code.Thank you

Please use [code]code here...[/code] tags when posting code.

What happens when this code is executed?

Are you trying to save the full activity or only ScrollView1?

 

[Mark Read]

please use code tags when posting, it makes things easier to read.

I am using almost the same code, the only difference is in one line (which I don't understand anyway!)

Obj1.Target = Obj1.GetActivityBA
Obj1.Target = Obj1.GetField("vg")

Erel, nothing happens. I've tried with scrollview, with panel, with activity, but nothing happens. No error message, but no screenshot

 

[Erel]

Please create a small example of the full code that is not working and upload it (File - Export as zip).

thanks again

You have forgotten to initialize the canvas.

Also, I did not understand if you want to get the screenshot or a copy of the ScrollView internal panel.

Thank you Luca. In the original program I didn't forget to initialize the canvas and the cod didin't work anyway. However, I think I have understood now. Instead of dirinternal I must write dirRootExternal, to save the picture on my phone.
This new code works for me.

Luca volevo fare in modo che gli utenti salvassero gli oggetti che modificavano nel panel, e poichè è scorrevole un semplice screenshot non va bene. Anche questo codice comunque non è perfetto perchè la foto è salvata in posti strani, ancora devo capire come fare per far salvare il file dove uno vuole.

Non so bene cosa vuoi ottenere, chiaramente, ma probabilmente ti conviene usare una CustomListView, molto più semplice da gestire.
A meno che non ci siano problemi di versioni di Android, l'immagine puoi salvarla in tre posti: DirDefaultExternal (consigliata), DirInternal, DirRootExternal.
Allego un esempio che salva soltanto il contenuto di una ScrollView (cosa che si può fare anche con la CustomListView, essendo questa una ScrollView).

I don't know exactly what you want to achieve, of course, but probably you should use a CustomListView, much easier to handle.
Unless there are problems of Android versions, you can save the image to: DirDefaultExternal (recommended), DirInternal, DirRootExternal.
I attach an example that saves only the contents of a ScrollView (which can also be done with the CustomListView, which is a ScrollView).

with this code I don't get any picture on my phone

No, no, I found it. Thank you for your time
