ボレーアンドロイドはjsonのデータではなく、エラーを表示しません

Question

私はアンドロイドアプリケーションを構築しています。私のコードは、LogCatもエラーも表示されませんが、私は私のアプリを実行するときには、 "Loading ...."というダイアログだけが表示されます。誰も私がこの問題を解決するのを助けることができますか？ はここにこれが私のItemAdapterある

public class AppController extends Application { 

public static final String TAG = AppController.class.getSimpleName(); 
private RequestQueue mRequestQueue; 
private ImageLoader mImageLoader; 
private static AppController mInstance; 


@Override 
public void onCreate() { 
    super.onCreate(); 
    mInstance=this; 
} 

public static synchronized AppController getmInstance(){ 
    return mInstance; 
} 

public RequestQueue getmRequestQueue(){ 
    if(mRequestQueue == null){ 
     mRequestQueue=Volley.newRequestQueue(getApplicationContext()); 
    } 
    return mRequestQueue; 
} 

public ImageLoader getmImageLoader(){ 
    getmRequestQueue(); 
    if (mImageLoader==null){ 
     mImageLoader = new ImageLoader(this.mRequestQueue, new BitmapCache()); 
    } 
    return this.mImageLoader; 
} 

public <T> void addToRequestQueue (Request<T> request, String tag){ 
    request.setTag((TextUtils.isEmpty(tag) ? TAG : tag)); 
    getmRequestQueue().add(request); 
} 


private <T> void addToRequestQueue(Request<T> request) { 
    request.setTag(TAG); 
    getmRequestQueue().add(request); 
} 


public void cancelPendingRequest (Object tag){ 
    if (mRequestQueue!=null){ 
     mRequestQueue.cancelAll(tag); 
    } 
} 
} 

私たManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="movies.esprit.tn.edu.moviesparsingjson" > 
<uses-permission android:name="android.permission.INTERNET"/> 
<application 
    android:name=".AppController" 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name=".MainActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

のAppController（私のカスタマイズされたアダプタ）

public class ItemAdapter extends BaseAdapter { 
private Activity activity; 
private LayoutInflater inflater; 
private List<Item> items; 
private ImageLoader imageLoader = AppController.getmInstance().getmImageLoader(); 
public ItemAdapter(Activity activity, List<Item> items){ 
    this .activity = activity; 
    this.items=items; 
} 
@Override 
public int getCount() { 
    return items.size(); 
} 

@Override 
public Object getItem(int position) { 
    return items.get(position); 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    if (inflater == null){ 
     inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 
    if(convertView==null){ 
     convertView = inflater.inflate(R.layout.custom_layout,null); 
    } 
    if (imageLoader==null){ 
     imageLoader=AppController.getmInstance().getmImageLoader(); 
     NetworkImageView imageView = (NetworkImageView) convertView.findViewById(R.id.thumbnail); 
     TextView title = (TextView) convertView.findViewById(R.id.titile); 
     TextView rating = (TextView) convertView.findViewById(R.id.rating); 
     Item.ResultsEntity item = (Item.ResultsEntity) getItem(position); 
     imageView.setImageUrl(item.getPoster_120x171(),imageLoader); 
     title.setText(String.valueOf(item.getTitle())); 
     rating.setText(String.valueOf(item.getRating())); 

    } 
    return convertView; 
} 
} 

これは私のmainActivityある

public class MainActivity extends AppCompatActivity { 

private static final String url = "http://api-public.guidebox.com/v1.43/Tunisia/rKgEWJbFg0kgEHrcGXPKhPDo0XtTafyC/movies/all/250/250"; 
private ProgressDialog dialog; 
private List<Item> array=new ArrayList<Item>(); 
private ListView listView; 
private ItemAdapter adapter; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    listView = (ListView) findViewById(R.id.list_item); 
    adapter = new ItemAdapter(this, array); 
    listView.setAdapter(adapter); 
    dialog = new ProgressDialog(this); 
    dialog.setMessage("Loading.... "); 
    dialog.show(); 

    JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(url, new Response.Listener<JSONArray>() { 
     @Override 
     public void onResponse(JSONArray jsonArray) { 
      hideDialog(); 
      for (int i = 0; i<jsonArray.length(); i++){ 
       try { 
        JSONObject obj = jsonArray.getJSONObject(i); 
        Item.ResultsEntity item = new Item.ResultsEntity(); 
        item.setTitle(obj.getString("title")); 
        item.setPoster_120x171(obj.getString("poster_120x171")); 
        item.setRating(obj.getString("rating")); 

       }catch (JSONException ex){ 
        ex.printStackTrace(); 
       } 
      } 

      adapter.notifyDataSetChanged(); 
     } 
    }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError volleyError) { 

     } 
    }); 

    AppController.getmInstance().addToRequestQueue(jsonArrayRequest,url); 
} 

public void hideDialog(){ 
    if (dialog!=null){ 
     dialog.dismiss(); 
     dialog=null; 
    } 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 
} 

は最後にこれは私がこの問題に対する答えを得ていないので、私はレトロフィットと協力し、それが魅力のように働いたLogCat
