Android Question Fading out text / views, making the display dim.

[Russ]

Hello,

I have a requirement I'm struggling with a bit. I have Labels, Buttons, ImageViews, SeekBars, Checkboxes etc etc... and after a set period of time I'd like to make them become darker or a bit transparent, something to hide them a little until activated again.

I am able to do this with labels, I can just set the alpha to 30%. I'm not sure what to do for other controls.

Another idea I had was to float a panel above the views, set it to black and set the alpha again. The only trouble with this approach is it also makes the background or other things around the view items appear darker.

Does anyone have any good ideas for this please?

Thank you

One panel for each view

You can also use AnimationPlus library to do it. Change the alpha level with InitializeAlpha and set PersistAfter to true.

LucaMs - I already have the views on a panel with 0 alpha, but it doesn't affect the transparency of the objects in it. Is that what you meant?

Erel - Thank you, I'll have a go with that tonight and see how I get on

I was referring to this part of your post:
"Another idea I had was to float a panel above the views, set it to black and set the alpha again"

but you can try most easly using AnimationPlus, as Erel has suggested.

Ahh hah, yeah my views aren't rectangular so it'd be hard to pull off but I could always have a darkened panel are that would look neat.

Thanks
