Question

我是Android Studio的新手，并且在解析JSON时遇到问题。这是我的JSON：

List<WebElement> amtButton = driver.findElements(By.xpath("//select[@id='amt']"));
    if(amtButton.size()==1){
       amtButton.get(0).click();
    }

我尝试这样解析它：

[{

        Year: "2017",

        Response: true,
        Type: "Movie"
      }]

我收到以下错误：

类型org.json.JSONArray无法转换为JSONObject

我知道我需要使用RequestQueue queue = new Volley().newRequestQueue(this); final JsonObjectRequest jsonArrayRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { Gson gson = new Gson(); MovieModel movieModel = gson.fromJson(response.toString(), MovieModel.class); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { Toast.makeText(MainActivity.this, error.toString(), Toast.LENGTH_SHORT).show(); } }); queue.add(jsonArrayRequest);而不是JsonArrayRequest，但是我不知道该如何获取对象？我搜索了其他帖子，但听不懂！

您能帮我学习吗？

Answer 1

    RequestQueue queue = new Volley().newRequestQueue(this);
            final JsonObjectRequest jsonArrayRequest = new JsonObjectRequest(Request.Method.GET, url, null,
                    new Response.Listener< JSONArray>() {
                        @Override
                        public void onResponse(JSONArray response) {
                            Gson gson = new Gson();

List<MovieModel> movieModels = gson.fromJson(response.toString(), List.class);
MovieModel movieModal = movieModels.get(0);
                        }
                    },
                    new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {
                            Toast.makeText(MainActivity.this, error.toString(), Toast.LENGTH_SHORT).show();
                        }
                    });

                    queue.add(jsonArrayRequest);

Answer 2

您已经将response作为JSONArray。

因此，您可以致电

JSONObject jresponse = response.getJSONObject(0);

在onResponse内部分析您的回复。

JSONObject jresponse = response.getJSONObject(0);
String title= jresponse.getString("Title");
Log.d("title", title);

我希望这会对您有所帮助。
