我正在尝试从themovidedb api获取电视节目列表，并且不断出现以下错误，这是我是android新手，这是我第一次使用api，请告诉我是否需要提供更多代码。感谢您的帮助。
请注意，我注意到目前仍在尝试使用此信息填充recyclerview。
错误
com.android.volley.ParseError: org.json.JSONException: Value {"page":1,"total_results":20000,"total_pages":1000,"results":[{"original_name":"Doom Patrol"....
我的代码
@Override
protected Void doInBackground(Void... voids) {
popularTvShows = "https://api.themoviedb.org/3/tv/popular?api_key=****my api key goes here****";
popularList = new ArrayList<>();
RequestQueue requestQueue = Volley.newRequestQueue(Objects.requireNonNull(getActivity()));
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(
Request.Method.GET,
popularTvShows,
null,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
try {
for (int i = 0; i < response.length(); i++) {
JSONObject jsonObject = response.getJSONObject(i);
Series series = new Series();
series.setId(jsonObject.getInt("id"));
series.setVoteAverage(jsonObject.getInt("vote_average"));
series.setVoteCount(jsonObject.getInt("vote_count"));
series.setOriginalTitle(jsonObject.getString("original_title"));
series.setTitle(jsonObject.getString("title"));
series.setPopularity(jsonObject.getDouble("popularity"));
series.setOverview(jsonObject.getString("overview"));
series.setReleaseDate(jsonObject.getString("release_date"));
series.setPosterPath(jsonObject.getString("poster_path"));
popularList.add(series);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@SuppressLint("ShowToast")
@Override
public void onErrorResponse(VolleyError error) {
Log.e("gggg", error.toString());
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
//This indicates that the reuest has either time out or there is no connection
Toast.makeText(getActivity(),"Check your internet and try again!", Toast.LENGTH_LONG);
} else if (error instanceof AuthFailureError) {
//Error indicating that there was an Authentication Failure while performing the request
Toast.makeText(getActivity(), "Authentication failure!", Toast.LENGTH_LONG);
} else if (error instanceof ServerError) {
//Indicates that the server responded with a error response

根据您的JSONObject，您的回复来自JSONArray，而不是Exception：
com.android.volley.ParseError: org.json.JSONException: Value {"page":1,"total_results":20000,"total_pages":1000,"results":[{"original_name":"Doom Patrol"...
执行此操作：
@Override
protected Void doInBackground(Void... voids) {
popularTvShows = "https://api.themoviedb.org/3/tv/popular?api_key=****my api key goes here****";
popularList = new ArrayList<>();
RequestQueue requestQueue = Volley.newRequestQueue(Objects.requireNonNull(getActivity()));
JSONObjectRequest jsonObjectRequest = new JSONObjectRequest(
Request.Method.GET,
popularTvShows,
null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
JSONObject json = new JSONObject(response);
JSONArray results = json.optJSONArray("results");
try {
for (int i = 0; i < results.length(); i++) {
JSONObject jsonObject = results.getJSONObject(i);
Series series = new Series();
.
.
.
popularList.add(series);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@SuppressLint("ShowToast")
@Override
public void onErrorResponse(VolleyError error) {
Log.e("gggg", error.toString());
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
//This indicates that the reuest has either time out or there is no connection
Toast.makeText(getActivity(),"Check your internet and try again!", Toast.LENGTH_LONG);
} else if (error instanceof AuthFailureError) {
//Error indicating that there was an Authentication Failure while performing the request
Toast.makeText(getActivity(), "Authentication failure!", Toast.LENGTH_LONG);
} else if (error instanceof ServerError) {
//Indicates that the server responded with a error response
Toast.makeText(getActivity(), "Server error! Try again later", Toast.LENGTH_LONG);
} else if (error instanceof NetworkError) {
//Indicates that there was network error while performing the request
Toast.makeText(getActivity(), "Network error", Toast.LENGTH_LONG);
} else if (error instanceof ParseError) {
// Indicates that the server response could not be parsed
Toast.makeText(getActivity(), "Parse Error", Toast.LENGTH_LONG);
}
}
}
);
requestQueue.add(jsonObjectRequest);
return null;
