Android back button (Solved)

[EddieLee]

Hi all,

I have a cd “homepage” and a cd “editpage”. There’s a code in the card script on my cd “editpage” that states:

Code: Select all

On backkey 
Go to cd “homepage”
End backkey 

So what I’m trying to do now is when the user clicks on the back button in cd “editdishes” I do not want the preopencard handler of cd “homepage” to run, or I only want parts of the code to run. Is there any script that I can write on the preopencard handler that let livecode know that it just came from Backkey handler of cd “editpage”?

Hi EddieLee,
Yes, you have to store the name of the closed cd into a variable or customprop and use this on your preopencard message.
Something like that:

backs btn script

Code: Select all

global gMyPrevCD
on mouseup
   put the short name of this cd into gMyPrevCD
end mouseup

homepage script

Code: Select all

global gMyPrevCD
on preopencard
   if gMyPrevCD = “editdishes” then -- gMyPrevCD is the name of a global variable
      
   else
     -- do something
   end if
   put empty into gMyPrevCD -- don't forget to reset variable
end preopencard

Best regards
Jean-Marc

Just use RECENT CARD!

Code: Select all

on preopencard
   if the short name of recent cd = “editdishes” then
     ## Do this
   else
     ## Do something else
   end if
end preopencard
