Android Question Problem with array button click new 2

[juniorteacher]

i use array to make button,
how i identify that button i click?

dim button(13) as button

for i =  0 to 13 -1
but(i).Initialize("But")
Activity.AddView(but(i),10%x + (i*11.5%x),14.5%y,11.5%x,8.3%y)
next

sub but(0)_click 'error in here
msgbox("test","test")
end sub

please give me an example

 

[juniorteacher]

if use but.tag

i can't use function like but(0).enable =true

 

[sorex]

put the array number (i in your case) as tag and then you should be able to do

sub but_click
dim b as button
b=sender
log(b.tag)
buttons(b.tag).enable=false
end sub

you better change the arrayname to buttons to avoid confusion

 

[klaus]

Or simply:

Sub But_Click
    Dim b as Button
    b = Sender
    b.Enable = false
End Sub

indeed Klaus, since it's the same button anyway that's even shorter.

sub but_click
dim b as button
b=sender
log(b.tag)
buttons(b.tag).enable=false
end sub

buttons ???
i'm already change it, but pull down menu did show the option for enable

Or simply:

Sub But_Click
    Dim b as Button
    b = Sender
    b.Enable = false
End Sub

i have 13 button and give tag name every button
can it disable button from button tag name like

Sub But_Click
    Dim b(13) as Button = sender
    Dim btnid as int = btn().tag ' error in here
b(12).Enable = false ' error in here
End Sub

 

[sorex]

it seems you don't really understand what you are writing there.

look again at my example and the one from Klaus. It's all there.

 

[juniorteacher]

my question is simple,
how to make array button with single click and disable the button from name tag

 

[sorex]

you will need to loop through the array and check the tags. if the right one passes you disable it.

 

[juniorteacher]

dim buttons(13) as button
for i = 0 to 13 -1
buttons(i).Initialize("buttons")
buttons(i).tag = i
next

sub buttons_click
dim b as button = sender
bid = b.tag
b(btag).enable = false
end sub

i want buttons(0) can disable buttons(3) or buttons(5)

 

[sorex]

sub buttons_click
dim b as button = sender
bid = b.tag
b.enable = false
if bid=0 then
 buttons(3).enable=false
 buttons(5).enable=false
end if
end sub

I suppose the problem is that you are not declaring the buttons as Global variables. You must do so to be able to use them in the "buttons_click" event

Sub Globals
  Dim buttons(13) as button
end sub
Sub Activity_Create(FirstTime as Boolean)
  for i = 0 to 13 -1
    buttons(i).Initialize("buttons")
    buttons(i).tag = i
  next
end sub

Sub buttons_click
  dim b as button = sender
  bid = b.tag
  if bid=0 then
    buttons(3).enable=false
    buttons(5).enable=false
  endif
end sub
