How to disable certain keys (say number/symbol keys) in Android virtual keyboard?

You can't, sorry. After all, the input method editor may not have "keys" in the first place.

Specifically I want user can't input a double quote ( " ) character when virtual keyboard is showed up when user focus on a standard android EditText widget.

Then you will have to block the input at the EditText, by means of an InputFilter, as is described here: How do I use InputFilter to limit characters in an EditText in Android?
