Android中验证输入是否为汉字及手机号，邮箱验证，IP地址可用端口号验证

1，验证是否为汉字

// 验证昵称
private boolean verifyNickname() {
String nickname = edt_username.getText().toString();
if (nickname == null || nickname.length() == 0) {
edt_username.setError("不能为空");
return false;
}
int len = 0;
char[] nickchar = nickname.toCharArray();
for (int i = 0; i < nickchar.length; i++) {
if (isChinese(nickchar[i])) {
len += 2;
} else {
len += 1;
}
}
if (len < 4 || len > 15) {
edt_username.setError("正确的昵称应该为\n1、4-15个字符\n2、2-7个汉字\n3、不能是邮箱和手机号");
return false;
}
return true;
}

private boolean isChinese(char c) {
Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
|| ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
|| ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
|| ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
return true;
}
return false;
}

2，验证手机号，邮箱

// 判断是否为手机号
private boolean isPhone(String inputText) {
Pattern p = Pattern
.compile("^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$");
Matcher m = p.matcher(inputText);
return m.matches();
}

// 判断格式是否为email
public boolean isEmail(String email) {
String str = "^([a-zA-Z0-9_\\-\\.]+)@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.)|(([a-zA-Z0-9\\-]+\\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\\]?)$";
Pattern p = Pattern.compile(str);
Matcher m = p.matcher(email);
return m.matches();
}

3，IP地址可用端口号验证，可用端口号（1024-65536）

private boolean MatcherIP(String ip) {
Pattern pattern = Pattern.compile("^((?!\\d\\d\\d)\\d+|1\\d\\d|2[0-4]\\d|25[0-5])"
+ "\\.((?!\\d\\d\\d)\\d+|1\\d\\d|2[0-4]\\d|25[0-5])"
+ "\\.((?!\\d\\d\\d)\\d+|1\\d\\d|2[0-4]\\d|25[0-5])"
+ "\\.((?!\\d\\d\\d)\\d+|1\\d\\d|2[0-4]\\d|25[0-5])"
+ ":((102[4-9])|(10[3-9]\\d)|([1-5]\\d{3,4})|(6[0-4]\\d{3})|(65[0-4]\\d{2})|(655[0-2]\\d)|(6553[0-5]))$");

Matcher matcher = pattern.matcher(ip);
return matcher.matches();
}

4,匹配/* 1234567890 */（“/*”开头，中间包含数字空格，以 “*/”结尾）

Pattern pattern = Pattern.compile("/*\\/*\\s*\\d*\\s*\\*/*");
Matcher matcher = pattern.matcher("正则表达式 /*  123   */ Hello World,正则表达式 Hello World");
//替换第一个符合正则的数据
System.out.println(matcher.replaceAll(""));

5 ，常用的eclipse搜索的正则表达式

1，Eclipse ctrl+f 打开查找框
2，选中 Regular expressions (正则表达式)

去掉/* */(eclipse)        /\*(.|[\r\n])*?\*/
去掉//(eclipse)             //.*$
去掉import(eclipse)     import.*$
去掉空行(eclipse)         ^\s*\n
去掉空行(ue)               %[ ^t]++^p

6,视频播放进度条中时间显示

//分钟

String am = String.format("%02d", tTotal / 60);

//秒

String as = String.format("%02d", tTotal % 60);

tiempoTotal.setText(am + ":" + as);
