我在工作遇到公司的要求,就是EditText判断输入字符串是否姓名、手机号、身份证号码…,这样是常用的业务
1.姓名  代码如下:
public static boolean isAllChinese(String str){
if(isNullOrEmpty(str))return true;
String overseerInfo = "^([\\u4e00-\\u9fa5]|\\ue82d)+$";
Pattern pattern=Pattern.compile(overseerInfo);
Matcher matcher=pattern.matcher(str);
if(!matcher.matches()){
return false;
}
return true;
}
2.身份证号码  代码如下:
public static boolean isIdentNum(String identNum) {
if (identNum.length() != 18) {
return false;
}
Pattern pattern = Pattern.compile("[0-9]{10}[0,1]{1}[0-9]{1}[0,1,2,3]{1}[0-9]{4}([0-9]|[X]){1}");
if (!pattern.matcher(identNum).matches()) {
return false;
}
int year = Integer.parseInt(identNum.substring(6, 10));
int month = Integer.parseInt(identNum.substring(10, 12));
int day = Integer.parseInt(identNum.substring(12, 14));
if (year < 1800 || year > 2100) {
return false;
}
if (month < 1 || month > 12) {
return false;
}
int[] monthDayNum;
if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
monthDayNum = new int[] { 31, 29, 31, 30, 31, 30, 31, 31, 30, 31,30, 31 };
} else {
monthDayNum = new int[] { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31,30, 31 };
}
if (day < 1 || day > monthDayNum[month - 1]) {
return false;
}
int[] factor = new int[] { 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5,8, 4, 2, 1 };
String[] parity = new String[] { "1", "0", "X", "9", "8", "7", "6","5", "4", "3", "2" };
int sum = 0;
for (int i = 0; i < 17; i++) {
sum += Integer.parseInt(identNum.substring(i, i + 1)) * factor[i];
}
int bitIndex = sum % 11;
String checkBit=identNum.substring(17);;
if (!checkBit.equals(parity[bitIndex])) {
return false;
}
return true;
}
3.手机号或者电话  代码如下:
public static boolean isMobilePhone(CharSequence inputStr){
String mobile = "^(1[3456789]+\\d{9})$";
Pattern pattern=Pattern.compile(mobile);
Matcher matcher=pattern.matcher(inputStr);
if(!matcher.matches()){
return false;
}
return true;
}
4.EditText判断输入字符串
......
dialog = DialogUtil.createInpDefault(MainActivity.this, new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
if (errHintTv != null && ensureBtn != null){
if ("name".equals(Type)){
if (!CharSeqUtil.isAllChinese(s.toString())){
ensureBtn.setEnabled(false);
errHintTv.setText("姓名只能是汉字!");
errHintTv.setVisibility(View.VISIBLE);
}else {
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}
}else if ("identNum".equals(Type)){
if (!CharSeqUtil.isIdentNum(s.toString())) {
ensureBtn.setEnabled(false);
errHintTv.setText("无效的身份证号!");
errHintTv.setVisibility(View.VISIBLE);
} else {
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}
}else if ("telephone".equals(Type)){
ImageView phonetIv = dialog.getView(R.id.iv_phone);
PhoneViewUtils.showOrHindPhoneView(MainActivity.this, phonetIv, s.toString());
if (!CharSeqUtil.isMobilePhone(s.toString())) {
ensureBtn.setEnabled(false);
if (s.toString().equals("")) {
ensureBtn.setEnabled(true);
}
errHintTv.setText("手机号码格式错误!");
errHintTv.setVisibility(View.VISIBLE);
} else {
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}
}else if ("password".equals(Type)){
if (CharSeqUtil.isPassword(s.toString())){
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}else {
ensureBtn.setEnabled(false);
errHintTv.setText("无效的密码(只是字母、数字)");
errHintTv.setVisibility(View.VISIBLE);
}
}else if ("postcode".equals(Type)){
if (!CharSeqUtil.isPostCode(s.toString())) {
ensureBtn.setEnabled(false);
errHintTv.setText("无效的邮政编码!");
errHintTv.setVisibility(View.VISIBLE);
} else {
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}
}else if ("houseAveNum".equals(Type)){
int houseAveNum = CharSeqUtil.parseInt(s.toString(), -1);
if (houseAveNum == -1) {
ensureBtn.setEnabled(false);
errHintTv.setText("输入值只能是数字");
errHintTv.setVisibility(View.VISIBLE);
} else if (houseAveNum < 1 && houseAveNum > 300) {
ensureBtn.setEnabled(false);
errHintTv.setText("人均住房面积应不小于1且不大于最大允许值300");
errHintTv.setVisibility(View.VISIBLE);
} else {
errHintTv.setVisibility(View.GONE);
ensureBtn.setEnabled(true);
}
}
}
}
},new DialogUtil.OnResultCallback<CharSequence>(){
@Override
public void onResult(CharSequence obj){
}
});
if (dialog != null) {
dialog.show();
}
input = dialog.getView(R.id.et_dialog_inp);
errHintTv = dialog.getView(R.id.tv_err_hint);
ensureBtn = dialog.getView(R.id.btn_ensure);
......
