Android - Limit only one decimal point enter into a EditText

Question

I need help to only allow one decimal point to be entered into a EditText view. An example: I don't want 123.45.2 or 123..452 to be allowed. Once one decimal point is entered, no more are allowed.

Answer 1

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.
