Question

我必须解析下面的Json。我知道如何在JsonArray有钥匙的情况下从JsonArray获取Json。如果我没有钥匙，我该怎么做？

Answer 1

有效的JSON：

{
   "abc":[
      {
         "name":"Ram"
      },
      {
         "name":"Shyam"
      },
      {
         "name":"Mohan"
      },
      {
         "name":"Pankaj"
      },
      {
         "name":"Komal"
      }
   ]
}

Answer 2

try 
{
    JSONArray jsonArray = new JSONArray(jsonStrFromSoundCloud);

    for (int i = 0; i < jsonArray.length(); i++) {
        //loop in array
    }

} catch (JSONException e) {
        e.printStackTrace();
}

Answer 3

我得到了答案，我将这个数组绑定在一个json对象中。然后获取它。像这样。

"{\"data\":"+ jsonArray+"}";

Answer 4

我试图通过创建一个json数组来解决类似的问题。

[{“name”：“dave”， “时代”：23 }， { “名字”：“德克斯特” “年龄”：24 }]

这是我的POJO

public class MyPojo {

private String name;
private int age;
// Getter & Setters
}

这就是你需要做的就是将JSON解析为List对象。

Type listType = new TypeToken<ArrayList<MyPojo>>(){}.getType();

List<MyPojo> jsonObject = new Gson().fromJson(response, listType);

希望这会有所帮助。：）

修改

不要忘记导入：import java.lang.reflect.Type;

我如何解析这个Json数组？
