Android Question Press the button through code

Rizal Putra · Mar 23, 2014

What can I do to press the button through code, without knowing EventName of a button or Activity name.

usually in VB.NET, I use:

B4X:

Button1.PerformClick

how in B4A?

Put the logic from the button_click sub into a normal sub which you then just call...

Instead of

B4X:

sub button_click
' doing a lot of stuff here
end sub

you can do something like

B4X:

sub button_click
subwhodidthestuff
end sub
sub subwhodidthestuff
' doing a lot of stuff here
end sub

And if you then want to "simulate" a button click you just call the sub subwhodidthestuff

You can also call button_click directly.

However if you don't know the event name value then you can use JavaObject:

B4X:

Dim jo As JavaObject = button1
jo.RunMethod("performClick", null)
