    Play around with this however you like it.

    myEditText.setKeyListener(DigitsKeyListener.getInstance(true,true));

    Returns a DigitsKeyListener that
    accepts the digits 0 through 9, plus
    the minus sign (only at the beginning)
    and/or decimal point (only one per
    field) if specified.
