android中Parcel中文乱码的解决：巧用十六进制

把需要传递的中文转化成十六进制的字符串。

str的格式：

"48", "65", "6C", "6C", "6F", "CD", "FB", "BE", "A9", "D7", "E9"

private String hex2String(String str) { 
		 Log.d(LOG_TAG, "hex2String str = " + str);
		 if(str.indexOf(",") == -1){
			 return str;
		 }
		 String[] strArray = str.split(",");
//		 String[] strArray = {"48", "65", "6C", "6C", "6F", "CD", "FB", "BE", "A9", "D7", "E9"};
		 StringBuilder builder = new StringBuilder();
         for (int i = 0; i < strArray.length; i++) {
        	char ch = (char) Integer.parseInt(strArray[i], 16);
        	builder.append(new Character(ch).toString());
		}
         try {
			return new String(builder.toString().getBytes("ISO-8859-1"),"GBK");
		} catch (UnsupportedEncodingException e) {
			return null;
		}
       }

package cn.itcast.string;

public class Hex2String {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String str = "I love 中国";
		String s = toHexString(str);
		System.out.println(s);
		System.out.println(toStringHex(s));
	}

	//转化字符串为十六进制编码
	public static String toHexString(String str){
		String s = "";
		for (int i = 0; i < str.length(); i++) {
			char ch = str.charAt(i);
			s += Integer.toHexString(ch) + ",";
		}
		s = s.substring(0, s.length()-1);
		return s;
	}
	
	//十六进制编码转化为字符串  
	public static String toStringHex(String str){
		String[] strArray = str.split(",");
		StringBuilder sb = new StringBuilder();
		for (int i = 0; i < strArray.length; i++) {
			char ch = (char) Integer.parseInt(strArray[i], 16);
			sb.append(Character.toString(ch));
		}
		return sb.toString();
	}
