无法解析JSONException Android Studio
我不知道我的JSONData出了什么问题，但是我的代码捕获了JSONException ，可能它的值是无效的......？ 我与JSON数据的网址是：本网站。 我已经在这个网站上使用过Json ，它可以工作，但是Json没有这个页面...为什么？
这是我的代码：
public class Tab4Fragment extends Fragment {
private ConnectivityManager manager;
public static final String TAG = Tab4Fragment.class.getSimpleName();
private CurrentEventsString mCurrentEventsString;
@InjectView(R.id.eventsText)
TextView mJsonText;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (container == null) {
return null;
}
View view = inflater.inflate(R.layout.tab_frag4_layout, container, false);
ButterKnife.inject(this, view);
String urlWebSite = "http://www.bundoransurfco.com/events/?json=1";
if (isNetworkAvailable()) {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(urlWebSite)
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
Log.d(TAG, "onFailure Network");
}
@Override
public void onResponse(Response response) throws IOException {
try {
String jsonData = response.body().string();
Log.d(TAG, "onResponse jsonData : "+jsonData);
if (response.isSuccessful()) {
mCurrentEventsString = getCurrentDetails(jsonData);
Log.d(TAG, "onResponse Successful");
// Write in the main Thread.
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
updateTextEvents();
Log.d(TAG, "UITHREAD");
}
});
} else {
alertUserAboutError();
Log.d(TAG, "ERROR");
}
} catch (IOException e) {
Log.e(TAG, "Exception caught: ", e);
} catch (JSONException e) {
Log.e(TAG, "Exception caught: ", e);
}
}
});
} else {
Toast.makeText(getActivity(), getString(R.string.network_unavailable_message), Toast.LENGTH_LONG).show();
}
Log.d(TAG, "Main UI code is running!");
return view;
}
private void updateTextEvents() {
mJsonText.setText(mCurrentEventsString.getJsonContent());
}
private boolean isNetworkAvailable() {
manager = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = manager.getActiveNetworkInfo();
boolean isAvailable = false;
if (networkInfo != null && networkInfo.isConnected()) {
isAvailable = true;
}
return isAvailable;
}
private void alertUserAboutError() {
AlertDialogFragment dialog = new AlertDialogFragment();
dialog.show(getActivity().getFragmentManager(), "error_dialog");
}
private CurrentEventsString getCurrentDetails(String jsonData) throws JSONException {
JSONObject events = new JSONObject(jsonData);
JSONObject postJson = events.getJSONObject("posts");
CurrentEventsString currentEventsString = new CurrentEventsString();
String contentString = postJson.getString("content");
//Events String
String jsonText = stripHtml(contentString);
Log.i(TAG, "CHECK THAT :" +jsonText);
currentEventsString.setJsonContent(jsonText);
return currentEventsString;
}
//Delete HTML Markup
public String stripHtml(String html) {
return Html.fromHtml(html).toString();
}
}
我的代码停止后String jsonData = response.body().string(); 并进入Log.e(TAG, "Exception caught: ", e);
我想要从帖子 > 内容的字符串
我该如何解决这个问题？ 干杯!

“posts”属性不是JSONObject，它是一个JSONArray。
尝试在getCurrentDetails方法中更改此行
JSONObject postJson = events.getJSONObject("posts");
至
JSONArray postJson = events. getJSONArray("posts");
您应该对JSONObject或JSONArray进行一些主动检查。
您可以使用以下方法来完成此操作：
Object obj = new JSONTokener(stringData).nextValue();
if (obj instanceof JSONObject)
//you got JSONobject here
else if (obj instanceof JSONArray)
//you got JSONArray here
你可以使用jsonArray和jsonObject获取数据，听说你可以看到如何使用api到你的应用程序的例子。 例子，例子2
