Hi, Im using ViewIMage(s) tu simulate Android icons.
Any way of doing something when the user touchs it?
Like blink or being black and white or something that indicate your touch is working?
Thanks

Android app icons don't have any tactile response to a touch. The response is to perform an action. Having said that, if you search the forum there are several examples of using an ImageView as a button.

I think you are wrong, in Android when you touch an icon it becomes gray.
Ive seached the forum but did not found any example of how to do it.
Thanks

Android app icons aren't reactive. Icons inside apps may or may not be. For example in some Android versions action bar icons go gray when you tap them & in others they only go gray if you long tap them.

If you want the background of an image to go gray when you tap it, use a bitmap with a transparent background & use ColorDrawable & Canvas to change the background color of the ImageView.

To add to Colin's comment, some Launcher Apps, specially those that hijack the default OS Launcher, do provide some "reaction"... The likes of GoLauncher do. But, as Collin stated, this is a Launcher App that provides its own "reaction" features to its "icons".

To achieve similar results, you can use an image view alongside with the animation lib to make your "icons" reactive.
