最近遇見一個需求,要求輸入框只能輸入中文,遮蔽標點和表情.

下面是自己整理的,驗證通過,可以直接使用.

boolean aa = checkNameChese("中文");//判斷aa的boolean行,即可
/**
 * 檢測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;
}

/**
 * 判定輸入漢字
 */
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.GENERAL_PUNCTUATION) {
        return true;
}
    return false;
