android 字符长度限制，中文2个字符 ，英文1个字符

比如最大10个字符，若超过10个，则显示9或者8个字符加省略号.

public class CalTextLength {

public static String handleText(String str, int maxLen) {    if (TextUtils.isEmpty(str)) {        return str;    }    int count = 0;    int endIndex=0;    for (int i = 0; i < str.length(); i++) {        char item = str.charAt(i);        if (item < 128) {            count = count + 1;        } else {            count = count + 2;        }        if(maxLen==count || (item>=128 && maxLen+1==count)){            endIndex=i;        }    }    if (count <= maxLen) {        return str;    } else {        return str.substring(0, endIndex) + "...";    }}

}
