How to catch a soft keyboard 'enter/done' press?

I would开发者_开发知识库 like to know when the user presses the 'enter/done/next' key on the soft keyboard without the activity knowing which edittext box the user is in. I have seen some code, but it always uses the name of the edittext box that is being edited.

The app has numerous edittext boxes, and calculations are re-run anytime any one of the values in a edittext box is changed.

Then attach the OnEditorActionListener to all of them.
