Android Question Horizontal Scroll View - Accessing Individual Panels Inside

pauleffect · Jan 21, 2014

Hello.

I am trying to start an activity when user clicks one of the panels held by an Horizontal Scroll View.
I read it's done with tags but I couldn't figure out how.

I have a for loop generating the panels and an array holding the said panels.

Thanks.

You can start an activity using a String as parameter (the name of the activity to start).

Therefore, you could use the tag of panel to "save" the name of the activity to start and use it.

StartActivity(pnlSelected.Tag)

No dice.

You need to initialize the panels with an event name then create a sub {eventname}_Click, read the tag and start the activity.

Code from your previous question, if it's the same or related code.

B4X:

Dim Panels(667) As Panel
Sub CreatePanels
    For i = 0 to 666
        Dim cw as Panel
        cw.Initialize("Panels")
        cw.Tag = ActivityName 'See Note 1
        Panels(i) = cw
        Desiredview.Panel.AddView(cw,Left,Top,Width,Height)
    Next
End sub

Sub Panels_Click
   Dim P As Panel = Sender
   StartActivity(P.Tag)
End Sub

Note 1: You will need to decide how to assign the activity you want to start from each panel to the tag. Either within the loop using another array or list or separately:

B4X:

Panels(n).Tag = ActivityName
