问题描述
这个错误是什么？我怎样才能解决这个问题？我的应用程序正在运行，但无法加载数据。这是我的错误：使用JsonReader.setLenient（true）在第1行第1列路径接受格式错误的JSON $
这是我的片段：
public class news extends Fragment {：
private RecyclerView recyclerView;
private ArrayList< Deatails>数据;
私人DataAdapter适配器;
private查看myFragmentView;
@Override
public查看onCreateView（LayoutInflater inflater，ViewGroup容器，Bundle savedInstanceState）{
myFragmentView = inflater.inflate（ R.layout.news，container，false）;
initViews（）;
返回myFragmentView;
$ b private void initViews（）{
recyclerView =（RecyclerView）myFragmentView.findViewById（R.id.card_recycler_view）;
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager（getActivity（）。getApplicationContext（））;
recyclerView.setHasFixedSize（true）;
recyclerView.setLayoutManager（layoutManager）;
data = new ArrayList< Deatails>（）;
adapter = new DataAdapter（getActivity（），data）;
recyclerView.setAdapter（adapter）;
new Thread（）
{
public void run（）
{
getActivity（）。runOnUiThread（new Runnable（）{
@Override
public void run（）{
loadJSON（）;
}
}）;
}
}
.start（）;
$ b $ private void loadJSON（）{
if（isNetworkConnected（））{
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor（）;
interceptor.setLevel（HttpLoggingInterceptor.Level.BODY）;
OkHttpClient client = new OkHttpClient.Builder（）
.addInterceptor（拦截器）
.retryOnConnectionFailure（true）
.connectTimeout（15，TimeUnit.SECONDS）
.build （）;
Gson gson = new GsonBuilder（）
.setLenient（）
.create（）;
Retrofit retrofit = new Retrofit.Builder（）
.baseUrl（http://www.memaraneha.ir/）
.client（客户端）
.addConverterFactory（GsonConverterFactory.create（gson））
.build（）;
RequestInterface request = retrofit.create（RequestInterface.class）;
呼叫< JSONResponse> call = request.getJSON（）;
final ProgressDialog progressDialog = new ProgressDialog（getActivity（））;
progressDialog.show（）;
call.enqueue（new Callback< JSONResponse>（）{
@Override
public void onResponse（Call< JSONResponse> call，Response< JSONResponse> response）{
progressDialog.dismiss （）;
JSONResponse jsonResponse = response.body（）;
data.addAll（Arrays.asList（jsonResponse.getAndroid（）））;
adapter.notifyDataSetChanged（）;
}
@Override
public void onFailure（Call< JSONResponse> call，Throwable t）{
progressDialog.dismiss（）;
Log.d（Error，t.getMessage （））;
}
}）;
}
else {
Toast.makeText（getActivity（）。getApplicationContext（），دستگاهشمابهاینترنتمتصلنیست！，Toast.LENGTH_LONG）.show（）;}
）
private boolean isNetworkConnected（）{
ConnectivityManager cm =（ConnectivityManager）getActivity（）。getSystemService（Context.CONNECTIVITY_SERVICE）;
NetworkInfo ni = cm.getActiveNetworkInfo（）;
if（ni == null）{
//没有活动的网络。
返回false;
} else
返回true;
$ / code $ / pre
$ bRequestInterface
public interface RequestInterface {
@GET（Erfan / news.php）
Call< JSONResponse>的getJSON（）;
}
解决方案这是已知问题，并基于 setLenient
<$ p $ Gson gson = new GsonBuilder（）
.setLenient（）
.create（）;
Retrofit retrofit = new Retrofit.Builder（）
.baseUrl（BASE_URL）
.client（客户端）
.addConverterFactory（GsonConverterFactory.create（gson））
.build（）;
如果您将此添加到改造中，现在会出现另一个错误：
com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期的BEGIN_OBJECT，但在第1行第1列为STRING $
这也是一个众所周知的错误，你可以找到答案这里（这意味着您的服务器响应格式不正确） ;因此，改变服务器响应返回以下内容：
{
android：[
{ver：1.5 ，名称：Cupcace，api：Api Level 3}
...
]
}
为了更好地理解，请将您的回答与 Github api 进行比较。
建议：找出 HttpLoggingInterceptor 在您的改造中。
基于这回答您的 ServiceHelper 为：
private ServiceHelper（）{
httpClient = new OkHttpClient.Builder（）;
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor（）;
interceptor.setLevel（HttpLoggingInterceptor.Level.BODY）;
httpClient.interceptors（）。add（interceptor）;
Retrofit retrofit = createAdapter（）。build（）;
service = retrofit.create（IService.class）;
}
另外，请不要忘记添加：
compile'com.squareup.okhttp3：logging-interceptor：3.3.1'
What is this error ? How can I fix this? My app is running but can't load data. And this is my Error: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $
This is my fragment :
public class news extends Fragment {
private RecyclerView recyclerView;
private ArrayList<Deatails> data;
private DataAdapter adapter;
private View myFragmentView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
myFragmentView = inflater.inflate(R.layout.news, container, false);
initViews();
return myFragmentView;
}
private void initViews() {
recyclerView = (RecyclerView) myFragmentView.findViewById(R.id.card_recycler_view);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(layoutManager);
data = new ArrayList<Deatails>();
adapter = new DataAdapter(getActivity(), data);
recyclerView.setAdapter(adapter);
new Thread()
{
public void run()
{
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
loadJSON();
}
});
}
}
.start();
}
private void loadJSON() {
if (isNetworkConnected()){
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.retryOnConnectionFailure(true)
.connectTimeout(15, TimeUnit.SECONDS)
.build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://www.memaraneha.ir/")
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
RequestInterface request = retrofit.create(RequestInterface.class);
Call<JSONResponse> call = request.getJSON();
final ProgressDialog progressDialog = new ProgressDialog(getActivity());
progressDialog.show();
call.enqueue(new Callback<JSONResponse>() {
@Override
public void onResponse(Call<JSONResponse> call, Response<JSONResponse> response) {
progressDialog.dismiss();
JSONResponse jsonResponse = response.body();
data.addAll(Arrays.asList(jsonResponse.getAndroid()));
adapter.notifyDataSetChanged();
}
@Override
public void onFailure(Call<JSONResponse> call, Throwable t) {
progressDialog.dismiss();
Log.d("Error", t.getMessage());
}
});
}
else {
Toast.makeText(getActivity().getApplicationContext(), "دستگاه شما به اینترنت متصل نیست!", Toast.LENGTH_LONG).show();}
}
private boolean isNetworkConnected() {
ConnectivityManager cm = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if (ni == null) {
// There are no active networks.
return false;
} else
return true;
}
}
RequestInterface :
public interface RequestInterface {
@GET("Erfan/news.php")
Call<JSONResponse> getJSON();
}
解决方案
This is known issue and based on this answer you should add setLenient:
Gson gson = new GsonBuilder()
.setLenient()
.create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
If you add this to your retrofit Now it's gives you another error:
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
This is also a well-known error you can find answer here (this is means that your server response is not well-formatted); So change server response to return following:
{
android:[
{ ver:"1.5", name:"Cupcace", api:"Api Level 3" }
...
]
}
For better comprehension compare your response with Github api.
Suggestion: to find out what's going on to your request/response add HttpLoggingInterceptor in your retrofit.
Based on this answer your ServiceHelper would be:
private ServiceHelper() {
httpClient = new OkHttpClient.Builder();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
httpClient.interceptors().add(interceptor);
Retrofit retrofit = createAdapter().build();
service = retrofit.create(IService.class);
}
Also don't forget to add:
compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
