You should add a TextWatcher to the EditText. This will notify you when the text changes.

When you know the text has changed, you can run it through a DecimalFormat: 

DecimalFormat decimalFormat = new DecimalFormat();
decimalFormat.setDecimalSeparatorAlwaysShown(true);
decimalFormat.setMaximumFractionDigits(2);

You can use a TextWatcher to look for modifications to the value in the field and insert a decimal point in the appropriate position as they type. See this SO question for an example of using a TextWatcher.
