public static void setPricePoint(final EditText editText) { editText.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if (s.toString().contains(".")) { if (s.length() - 1 - s.toString().indexOf(".") > 2) { s = s.toString().subSequence(0, s.toString().indexOf(".") + 3); editText.setText(s); editText.setSelection(s.length()); } } if (s.toString().trim().substring(0).equals(".")) { s = "0" + s; editText.setText(s); editText.setSelection(2); } if (s.toString().startsWith("0") && s.toString().trim().length() > 1) { if (!s.toString().substring(1, 2).equals(".")) { editText.setText(s.subSequence(0, 1)); editText.setSelection(1); return; } } } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } });
