json数组遇到问题

Question

首先感谢花时间看看我的问题，我是android开发新手，我遇到了一个来自PHP服务器的数组来自JSON编码的问题，我试着去看看对于答案，但JSON的所有示例使用字段名称来解码数组，我的字段名称不存在。

这是阵列，可以是许多串的一个例子：

[["104733","\u5e38\u4e16\u7530 \u9752","images\/myphoto\/104733_20120711101030_sq_s.jpg","062556","2012\/11\/21","test20121121-2","Test2\n\u643a\u5e2f\u304b\u3089","11.11","333.33","555.55","77.77","22:22:22","20:44:44","19:07:06","17:29:28",0," ","0"," "," ","61116",0," "] 
,["104733","\u5e38\u4e16\u7530 \u9752","images\/myphoto\/104733_20120711101030_sq_s.jpg","062555","2012\/11\/21","test20121121","Test\n\u643a\u5e2f\u304b\u3089","11.11","333.33","555.55","77.77","22:22:22","20:44:44","19:07:06","17:29:28",0," ","0"," "," ","61117",0," "]] 

基本上其中说\ u643a \ u5e2f \ u304b \ u3089是日语字符携帯から。

我设法使用这种循环手动分离字段，但仍然以编码格式获取名称。

     for(int i=0; i<num; i++){ 
      //Separate the string in to the different groups 
      endIdx = strcline.indexOf("]", startIdx)+1; 
      String temp = strcline.substring(startIdx, endIdx); 

      //Get the user id from the string temp 
      startIdx2 = 2; 
      endIdx2 = temp.indexOf(",", startIdx2) - 1; 
      String userId = temp.substring(startIdx2, endIdx2); 
      Log.v("temp", userId); 
      startIdx2 = endIdx2 + 3;

你的json是一个字符串数组的数组，这就是为什么你没有字段名。它们只存在于物体中。

用String操作解析json是件痛苦的事情。你应该看看org.json包中的类，并在这里开始解析JSONArray。

JSONArray a1 = new JSONArray(json); 
for (int i = 0; i < a1.length(); i++) { 
    JSONArray a2 = a1.getJSONArray(i); 
    for (int j = 0; j < a2.length(); j++) { 
    String s1 = a2.getString(j); 
     // ... 
    } 
}
