// 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;     }
