Android EditText 让编辑框只能输入中文汉字

最近做一项目，需求中有一特殊要求规定，检验编辑框（EditText）输入的内容是否全部是中文汉字，查阅大量资料，费劲九牛二虎之力，呵呵，如下代码：

/**
 * 判定输入汉字
 * @param c
 * @return
 */
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.GENERAL_PUNCTUATION
            || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
            || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
        return true;
    }
    return false;
}

/**
 * 检测String是否全是中文
 * @param name
 * @return
 */
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;
            break;
        }
    }
    return res;
}
