안드로이드,TextWatcher 실시간으로 입력값에 콤마구분하기 (금액관련필드)

public class TextWatcher_MoneyToComma implements TextWatcher { @SuppressWarnings("unused") private EditText mEditText; String strAmount = ""; // 임시 저장값 (콤마) public TextWatcher_MoneyToComma(EditText e) { mEditText = e; } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if (!s.toString().equals(strAmount)) { strAmount = setStrDataToComma(s.toString().replace(",", "")); mEditText.setText(strAmount); Editable e = mEditText.getText(); Selection.setSelection(e, strAmount.length()); } } protected String setStrDataToComma(String str) { if (str.length() == 0) return ""; long value = Long.parseLong(str); DecimalFormat format = new DecimalFormat("###,###"); return format.format(value); } }

사용법은 해당클래스는 TextWatcher로 선언해서 적용하고자 하는 EditText에

addTextChangedListener로 등록해주면 끝.
