篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Android EditText判断输入字符串的工具类集合相关的知识，希望对你有一定的参考价值。
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：
/**
* 中文验证
* @param str
* @return
*/
public static boolean isAllChinese(String str){
if(isNullOrEmpty(str))return true;
String overseerInfo = "^([\\\\u4e00-\\\\u9fa5]|\\\\ue82d)+$";
Pattern pattern=Pattern.compile(overseerInfo);
Matcher matcher=pattern.matcher(str);
if(!matcher.matches()){
return false;
}
return true;
}
2.身份证号码
代码如下：
/**
*验证身份证
* @param identNum
* @return
*/
public static boolean isIdentNum(String identNum) {
//二代身份证的长度
if (identNum.length() != 18) {
return false;
}
//验证二代身份证的格式
Pattern pattern = Pattern.compile("[0-9]{10}[0,1]{1}[0-9]{1}[0,1,2,3]{1}[0-9]{4}([0-9]|[X]){1}");
if (!pattern.matcher(identNum).matches()) {
return false;
}
int year = Integer.parseInt(identNum.substring(6, 10));
int month = Integer.parseInt(identNum.substring(10, 12));
int day = Integer.parseInt(identNum.substring(12, 14));
//验证年份是否超出常规
if (year < 1800 || year > 2100) {
return false;
}
//验证月份是否有效
if (month < 1 || month > 12) {
return false;
}
//验证天数是否有效
int[] monthDayNum;
if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
monthDayNum = new int[] { 31, 29, 31, 30, 31, 30, 31, 31, 30, 31,30, 31 };
} else {
monthDayNum = new int[] { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31,30, 31 };
}
if (day < 1 || day > monthDayNum[month - 1]) {
return false;
}
//验证因子是否有效
int[] factor = new int[] { 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5,8, 4, 2, 1 };
String[] parity = new String[] { "1", "0", "X", "9", "8", "7", "6","5", "4", "3", "2" };
int sum = 0;
for (int i = 0; i < 17; i++) {
sum += Integer.parseInt(identNum.substring(i, i + 1)) * factor[i];
}
int bitIndex = sum % 11;
String checkBit=identNum.substring(17);;
if (!checkBit.equals(parity[bitIndex])) {
return false;
}
return true;
}
3.手机号或者电话
代码如下：
public static boolean isMobilePhone(CharSequence inputStr){
// String mobile = "^(((13[0-9]{1})|(14[0-9]{1})|(15[0-9]{1})|(17[0-9]{1})|(18[0-9]{1}))+\\\\d{8})$";
String mobile = "^(1[3456789]+\\\\d{9})$";//最新的电话正则表达式与平台保持一致
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)){
//如果是电话显示 拨打
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);
......
5.CharSeqUtil.java,判断字符串工具类集合
public class CharSeqUtil {
public static boolean isNullOrEmpty(CharSequence str){
if(str==null||isEmpty(str)){
return true;
}else {
return false;
}
}
public static boolean isEmpty(CharSequence c){
int len = c.length();
int start = 0;
while (start < len && c.charAt(start) <= ' ') {
start++;
}
return len==start;
}
/**
* 验证是否含有汉字
* @param str
* @return
*/
public static boolean isHaveChinese(CharSequence str){
Pattern pattern=Pattern.compile("[\\u4e00-\\u9fa5]");
Matcher matcher=pattern.matcher(str);
if(matcher.find()){
return true;
}
return false;
}
/**
* 验证是否为整数
* @param str
* @return
*/
public static boolean isNumber(CharSequence str){
Pattern pattern = Pattern.compile("^[0-9]*$");
Matcher matcher = pattern.matcher(str);
return matcher.matches();
}
/**
* 验证是否为正整数
* @param str
* @return
*/
public static boolean isPositiveNumber(CharSequence str){
Pattern pattern = Pattern.compile("^[1-9]{1}[0-9]*$");
Matcher matcher = pattern.matcher(str);
return matcher.matches();
}
public static boolean isChLetterNum(CharSequence str){
Pattern pattern = Pattern.compile("^[0-9a-zA-Z\\u4e00-\\u9fa5]*$");
Matcher matcher = pattern.matcher(str);
return matcher.matches();
}
/**
*
* @param s
* @param defaultValue
* @return
*/
public static int parseInt(String s,int defaultValue){
try{
if(s==null||s.isEmpty()){
return defaultValue;
}
return Integer.parseInt(s);
}catch (Exception e){
// e.printStackTrace();
return defaultValue;
}
}
/**
*
* @param s
* @param defaultValue
* @return
*/
public static float parseFloat(String s, int defaultValue){
try{
if(s==null||s.isEmpty()){
return defaultValue;
}
return Float.parseFloat(s);
}catch (Exception e){
// e.printStackTrace();
return defaultValue;
}
}
public static long parseLong(String s, long defaultValue) {
try{
if(s==null||s.isEmpty()){
return defaultValue;
}
return Long.parseLong(s);
}catch (Exception e){
// e.printStackTrace();
return defaultValue;
}
}
/**
* 中文验证
* @param str
* @return
*/
