Question

(i have put the code at the end of my post)

i would like to make a hidden menu.

I don’t know if i take the good way.

I have some button visible, some invisible button and at the an another visible button.
One of the button in first layout have to set visible the hidden buttons.

I would like to have the last button just after the first bunch.
But like i have put invisible the Layout so i have an empty space.

I would like when i pressed the button for set visible that the last button go down.

I hope you will understand want i want to do and what i have done.

Answer 1

If I understand correctly you want to use android:visibility="gone" so that what ever you set to "gone" does not occupy any space on the layout.

Basically, instead of android:visibility="invisible" you should use android:visibility="gone"

See if that works.
