EditText保留小数点后面两位

@Override
public void afterTextChanged(Editable s) {

String result = s.toString();
if (result.contains(".")) {

String[] strs = result.split("\\.");
if (strs.length > 1 && strs[1].length() > 2) {

String endString = s.toString()
.subSequence(0, s.length() - (strs[1].length() - 2)).toString();
mEditText.setText(endString);
mEditText.setSelection(endString.length());
}
}
