The attribute maxLines corresponds to the maximum height of the EditText, it controls the outer boundaries and not inner text lines. If you want to change number of line use this code:

// set listeners
txtSpecialRequests.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        lastSpecialRequestsCursorPosition = txtSpecialRequests.getSelectionStart();
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        txtSpecialRequests.removeTextChangedListener(this);

        if (txtSpecialRequests.getLineCount() > 3) {
            txtSpecialRequests.setText(specialRequests);
            txtSpecialRequests.setSelection(lastSpecialRequestsCursorPosition);
        }
        else
            specialRequests = txtSpecialRequests.getText().toString();

        txtSpecialRequests.addTextChangedListener(this);
    }
});

You can change the value of 3 in txtSpecialRequests.getLineCount() > 3.
