最近遇见一个需求,要求输入框只能输入中文,屏蔽标点和表情.

下面是自己整理的,验证通过,可以直接使用.

boolean aa = checkNameChese("中文");//判断aa的boolean行,即可/** * 检测String是否全是中文 */public  boolean checkNameChese(String name){    boolean res=true;    char [] cTemp = name.toCharArray();    for(int i=0;i<name.length();i++)    {        if(!isChinese(cTemp[i])) {            res=false;        }else {            if ((cTemp[i] >= 0x4e00) && (cTemp[i] <= 0x9fbb)){                res=true;            }else {                res=false;            }        }    }    return res;}/** * 判定输入汉字 */public  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.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B            || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION            || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS            || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION) {        return true;    }    return false;}
