Trouble with ImageButton

[Nem1n]

Hello guys,

It seems that I have some trouble with the size of my ImageButton when I build Myapp.apk. In Android my ImageButtons are really small.

Hope somebody can help me.

This firt method crash my app:

Button:
    background_color: (0,0,0,0)
    id: button
    on_press:
        root.manager.transition.direction = "left"
        root.manager.current = 'experience'
    Image:
        source:'data/work.png'
        size: button.size
        pos: button.pos

This one work but the picture is too small

ImageButton:
    source:'data/education.png'
    on_press:
        root.manager.transition.direction = "left"
        root.manager.current = 'education'

Try and get the log so you can see why the first one crashes. It's probably to do with what happens in the 'on_press', as the rest looks fine. That should sort your sizing  problem, but you may want to set "allow_stretch" to True. Or maybe not..:-)

Hi, 

Thanks for the answer,

I' have no idea how to get the log, can you tell me please?

For the image button I change the size of the source for a bigger and it went bigger to the apk.

I have another question it's been few days I try to have a button who can scroll the view to the bottom or the middle of the page, how can I do that if it's possible?

Re scrolling, I assume you are using the ScrolView? Try scroll_to.
