预期BEGIN_ARRAY但是在改造

Question

我想从改造中接收数据，并在ListView中设置，但我有一个例外

  

retrofit.RetrofitError：com.google.gson.JsonSyntaxException：   java.lang.IllegalStateException：预期BEGIN_ARRAY但是   BEGIN_OBJECT在第1行第2列路径$

我该怎么办？

改造：

public class Retrofit {

    private static final String ENDPOINT = "https://maps.googleapis.com/maps/api/place";
    private static ApiInterface apiInterface;

    interface ApiInterface {
        @GET("/nearbysearch/json?location=49.9944422,36.2368201&radius=500&types=food&key=AIzaSyDQZoJKznf0uRkvJFqLYbZ7-1GeGudjmv0")
        void getBars(Callback<List<Bars>> callback);    
    }

    static {
        init();
    }

    private static void init() {
        RestAdapter restAdapter = new RestAdapter.Builder()
                .setEndpoint(ENDPOINT)
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .build();
        apiInterface = restAdapter.create(ApiInterface.class);
    }

    public static void getBars(Callback<List<Bars>> callback) {
        apiInterface.getBars(callback);
    }
}

类：

public class Bars implements Serializable {

    String name;
    String vicinity;

    public Bars(String name, String vicinity) {
        this.name = name;
        this.vicinity = vicinity;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getVicinity() {
        return vicinity;
    }

    public void setVicinity(String vicinity) {
        this.vicinity = vicinity;
    }
}

活动中的改造：

Retrofit.getBars(new Callback<List<Bars>>() {
    @Override
    public void success(List<Bars> bars, Response response) {

        listView.setAdapter(new MyAdapter(MainActivity.this, bars));
    }

    @Override
    public void failure(RetrofitError error) {

        Toast.makeText(getApplicationContext(), "Something Wrong", Toast.LENGTH_SHORT).show();
        Log.d("Retrofit error", error.toString());

    }
});

适配器：

class MyAdapter extends ArrayAdapter<Bars> {

    public MyAdapter(Context context, List<Bars> objects) {
        super(context, R.layout.list_item, objects);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        View rowView = convertView;
        if (rowView == null) {
            LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.textNameOfBar = (TextView) rowView.findViewById(R.id.name_id);
            holder.textVicinity = (TextView) rowView.findViewById(R.id.vicinity_id);

            rowView.setTag(holder);
        } else {
            holder = (ViewHolder) rowView.getTag();
        }

        Bars bars = getItem(position);
        holder.textNameOfBar.setText(bars.getName());
        holder.textVicinity.setText(bars.getVicinity());


        return rowView;
    }

    class ViewHolder {

        public TextView textNameOfBar;
        public TextView textVicinity;
    }
}

Answer 1

  

当响应在JSONObject中并且你创建了JSONArray POJO时出现了这个错误。我这样解决了我的问题。   使JSONObject POJO如下所示：

public class GetEventResult {

@SerializedName("event")
@Expose
private Event event;

public Event getEvent() {
    return event;
}

public void setEvent(Event event) {
    this.event = event;
}
}

  

而不是：

public class OneRegistryBeanResult {

@SerializedName("event")
@Expose
private List<Event> event = new ArrayList<Event>();

public List<Event> getEvent() {
    return event;
}

public void setEvent(List<Event> event) {
    this.event = event;
}
}
