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;
    }
       }

参考代码：

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();
  }
}
