Have you tried limiting the number of character of the EditText ? If not take a look at this

EditText et = new EditText(this);

int maxLength = 3;

InputFilter[] FilterArray = new InputFilter[1];

FilterArray[0] = new InputFilter.LengthFilter(maxLength);

et.setFilters(FilterArray);

Use EditText's setKeyListener method to set a custom KeyListener that limits the length of the text in the control

For reference:

In cases where I want to track more than one type of max limit (multiple field shared max limit, individual field max limit), I look at the selection position in the edit.

If the position is larger than my smallest max value, I just take the left max characters. If the position is smaller than my max value, I take the left position characters, subtract that from the max, then take the remaining right characters.

You only need to do this if you will have more than one possible limiter.
