Why buttons without icons in Material Design
In Google's Material Design, do the guidelines prefer buttons without icons next to text? On http://www.google.com/design/spec/components/buttons.html no such examples can be found. Is it written somewhere why?
(I know the floating action button or paper icon button have icons; I'm talking about text buttons.)
According to the developer pages (http://developer.android.com/design/building-blocks/buttons.html):
Both an icon and text is most appropriate when they complement each other: each carrying its own bit of information, but together making a larger whole.
This may be the contributing factor in the design guide where no such example is present
I might be late to this. But in Material Design website it does have a sample of it.
In most cases I think text only or icon only are sufficient to describe what it does. I came across a scenario where the button text describes the item that user is selecting and button icon describes what happens when the button is clicked. It seems more 'instructive' to me. But I may be wrong.
The following examples are from Material Design website.
Use icons that clearly communicate their meaning.
Donâ€™t vertically align an icon and text in the center of a contained button.
Donâ€™t use two icons in the same button.
