CustomDialog - Spinner control multi selection?

See the checked scrollview example: http://www.b4x.com/forum/basic4andr...23-scrollview-examples-summary.html#post47137

Thanks.

I can put the scrollview panel together fine - but I can't seem to Add it to a customdialog.

Have I missed something?

Or do I need to create a "modal" scrollview panel? If so, how would I do that?

Have you tried to to put it on a panel and add the panel to the custom view?

OK, this works fine.

So my question now would be - what is the proper of managing such a custom view?

I was thinking to have a number of the custom views added to an activity to manage a sequence of dialogs.

Then to capture the Activity Keypress code and switch between views accordingly using the .BringToFront and .SendToBack methods.

But I can't seem to get these methods to work?

Or is there a better practice for doing this?

Is this a modal dialog or a regular view?

Hi Erel,

It's a regular View.

I think I may have it worked this out using a combination of xxxView.RemoveView, xxxView.Visible and Activity_KeyPress:

In my Activity, I have a main View, 3 "dialog" views (nested) and a "screenGrayer" (which is a transparent, gray 100%x/100%y view used an overlay on previous dialog view).

I control all the views using:

1. an OK button (on each View) to save the selected values, etc

2. the Back button to display/remove the views in the Activity:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event

If KeyCode=KeyCodes.KEYCODE_BACK Then

If firstDialogView.Visible Then
' back to mainView
firstDialogView.RemoveView
screenGrayer.RemoveView
Return False

Else If secondDialogView.Visible Then
' back to firstDialogView
secondDialogView.RemoveView
firstDialogView.Visible=True
Return False

Else If thirdDialogView.Visible Then
' back to secondDialogView
thirdDialogView.RemoveView
secondDialogView.Visible=True
Return False

Else If mainView.Visible Then
' go back
Return True

End If

End If


End Sub

It seems to work ok. Is this the "right" way to manage the views, etc?

Thanks

After calling RemoveView you will need to add the view again if you want to show it. It is better to set Visible to False in this case.

Will do. Thanks.

Just noticing that Keypress_back seems very sensitive - ie it jumps back sometimes twice or three times.

Is there a way to slow this down?

You can save the time of the last back key press and ignore new presses if the time passed is too short.

I would have probably used multiple activities instead. This way everything will be handled automatically by the OS.

Thanks, Erel.

I think I will try the multiple Activities approach you suggest

... the more I think about it, the easier it sounds to implement and maintain custom "dialog" views using Activities.
