我是android的新手，正在研究如何解析Jso，所以请帮助我，我想解析这种类型的Json并希望得到“option_name”和“option_values”的值。请帮助我..我的代码是如下所示，我试过..

JSON示例

mycode的

if (jsonObj.has("product")) {

                        subCategories = jsonObj.getJSONArray("product");
                        if (subCategories != null
                                && subCategories.length() != 0) {

                            // looping through All Contacts

                            for (int i = 0; i < subCategories.length(); i++) {

                                JSONObject c = subCategories.getJSONObject(i);

                                sub_id = c.getString("id");
                                sub_name = c.getString("name");

                                thumb_image = c.getString("thumb_image");
                                big_image = c.getString("big_image");
                                resultArray.add(big_image);

                                JSONArray optsn = c
                                        .optJSONArray("product_options");

                                for (int j = 0; j < optsn.length(); j++) {

                                    JSONObject d = optsn.optJSONObject(j);

                                    sub_id = d.optString("option_name");
                                    sub_name = d.optString("option_value");
                                    System.out
                                            .println("::::::::::::::::option name and value:::::::::::"
                                                    + option_name
                                                    + " "
                                                    + option_value);
                                };

Answer 1

试试这个..

您从 jsonObj JSONArray获得产品 JSONObject同样获得 product_options JSONArray来自 c JSONObject

for (int i = 0; i < subCategories.length(); i++) {

    JSONObject c = subCategories.getJSONObject(i);

    sub_id = c.getString("id");
    sub_name = c.getString("name");

    thumb_image = c.getString("thumb_image");
    big_image = c.getString("big_image");

    if (c.has("product_options")) {
         JSONArray product_optionsarray = c.getJSONArray("product_options");

         for (int j = 0; j < product_optionsarray.length(); j++) {

                 JSONObject c1 = product_optionsarray.getJSONObject(j);

                 if (c1.has("option_name")) 
                    String option_name = c1.getString("option_name");

                 if (c1.has("option_value")) 
                     String option_value = c1.getString("option_value");
         }
    }
}

Answer 2

试试这个

        if (jsonStr != null) {

        jsonObj = new JSONObject(jsonStr);

        JSONArray categories = jsonObj.optJSONArray("product");
        for (int i = 0; i < categories.length(); i++) 
          {

            JSONObject category_object=categories.optJsonObject(i);
            JSONArray subCategories=category_object.optJSONArray("product_options");

                  for (int i = 0; i < subCategories.length(); i++) 
                   {

                       JSONObject c = subCategories.optJSONObject(i);

                       sub_id = c.optString("option_name");
                       sub_name = c.optString("option_value");
                    }

              }
         }

Answer 3

JSONTokener jk = yourJson; 
Object o = jk.nextValue();
if(o instanceof JSONObject){
      JSONObject jo = (JSONObject)o;
      // its an jsonobject.. use it, parse it, whatever
}else if(o instanceof JSONArray){
      JSONArray ja = (JSONArray)o;
      for(/** loop through your json array **/) {
      }
}else{ /* not a json string or corrupted **/    }

在您的情况下，您应该循环Object并解析它。您可以使用

获取所有可用密钥（用于调试）

 Iterator<String> yourKeys = object.keys();
 for( String s : yourKeys) System.out.println( s );

如何在特定对象的android中解析这个JSON
