Recyclerview不加载图像

我想从url使用抽象图像，但它不工作在加载数据应用程序崩溃时......但是当我删除图像加载器 evertything加载正确的文本数据... 我在Android的新的编码，从而无法找出问题..Recyclerview不加载图像

这里是我的适配器类

public class RecyclerViewDataAdapter extends RecyclerView.Adapter<RecyclerViewDataAdapter.ViewHolder> { 
private Pants context; 
public ImageLoader mImageLoader; 

//List of superHeroes 
List<ListOfData> superHeroes; 

public RecyclerViewDataAdapter(List<ListOfData> superHeroes, Pants context){ 
    super(); 
    //Getting all the superheroes 
    this.superHeroes = superHeroes; 
    this.context = context; 
} 

@Override 
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View v = LayoutInflater.from(parent.getContext()) 
      .inflate(R.layout.recyclerview_row, parent, false); 
    ViewHolder viewHolder = new ViewHolder(v); 
    return viewHolder; 
} 

@Override 
public void onBindViewHolder(ViewHolder holder, int position) { 
    ListOfData superHero = superHeroes.get(position); 

    mImageLoader = MyApplication.getInstance(context).getImageLoader(); 
    mImageLoader.get(superHero.getImageUrl(), ImageLoader.getImageListener(holder.imageView1, R.mipmap.ic_launcher, android.R.drawable.ic_dialog_alert)); 

    holder.imageView1.setImageUrl(superHero.getImageUrl(), mImageLoader); 
    holder.textViewName1.setText(superHero.getName()); 
    //holder.textViewRank.setText(String.valueOf(superHero.getRank())); 
    //holder.textViewRealName.setText(superHero.getRealName()); 
    //holder.textViewCreatedBy.setText(superHero.getCreatedBy()); 
    //holder.textViewFirstAppearance.setText(superHero.getFirstAppearance()); 

    String powers = ""; 

    /* for(int i = 0; i<superHero.getPowers().size(); i++){ 
     powers+= superHero.getPowers().get(i); 
    }*/ 

    //holder.textViewPowers.setText(powers); 

} 

@Override 
public int getItemCount() { 
    return superHeroes.size(); 
} 

class ViewHolder extends RecyclerView.ViewHolder{ 
    public NetworkImageView imageView1; 
    public NetworkImageView imageView2; 
    public TextView textViewName1; 
    public TextView textViewName2; 
    public TextView textViewRank; 
    public TextView textViewRealName; 
    public TextView textViewCreatedBy; 
    public TextView textViewFirstAppearance; 
    public TextView textViewPowers; 

    public ViewHolder(View itemView) { 
     super(itemView); 
     imageView1 = (NetworkImageView) itemView.findViewById(R.id.thumbnail); 
     imageView2 = (NetworkImageView) itemView.findViewById(R.id.thumbnail2); 
     textViewName1 = (TextView) itemView.findViewById(R.id.category_title_one); 
     textViewName2 = (TextView) itemView.findViewById(R.id.category_title_two); 
     /* textViewRank= (TextView) itemView.findViewById(R.id.textViewRank); 
     textViewRealName= (TextView) itemView.findViewById(R.id.textViewRealName); 
     textViewCreatedBy= (TextView) itemView.findViewById(R.id.textViewCreatedBy); 
     textViewFirstAppearance= (TextView) itemView.findViewById(R.id.textViewFirstAppearance); 
     textViewPowers= (TextView) itemView.findViewById(R.id.textViewPowers); 
     */ 
    } 
}

}

和JSON部分

public class Pants extends Fragment { 
private Pants context; 

//Creating a List of superheroes 
public List<ListOfData> listSuperHeroes; 

//Creating Views 
private RecyclerView recyclerView; 
private RecyclerView.LayoutManager layoutManager; 
private RecyclerView.Adapter adapter; 


public Pants() { 
    // Required empty public constructor 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    View view = inflater.inflate(R.layout.tshirts_pants_shirts, container, false); 

    recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view); 
    layoutManager = new LinearLayoutManager(getActivity().getApplicationContext()); 
    recyclerView.setLayoutManager(layoutManager); 


    //Calling method to get data 
    getData(); 
    return view; 
} 


private void getData() { 
    //Showing a progress dialog 
    final ProgressDialog loading = ProgressDialog.show(getActivity(), "Loading Data", "Please wait...", false, false); 

    //Creating a json array request 
    JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(ProductConfig.DATA_URL, 
      new Response.Listener<JSONArray>() { 
       @Override 
       public void onResponse(JSONArray response) { 
        //Dismissing progress dialog 
        loading.dismiss(); 

        //calling method to parse json array 
        parseData(response); 
       } 
      }, 
      new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 

       } 
      }); 

    //Creating request queue 
    RequestQueue requestQueue = Volley.newRequestQueue(getActivity()); 

    //Adding request to the queue 
    requestQueue.add(jsonArrayRequest); 
} 

//This method will parse json data 
private void parseData(JSONArray array) { 
    listSuperHeroes = new ArrayList<>(); 

    for (int i = 0; i < array.length(); i++) { 
     ListOfData superHero = new ListOfData(); 
     JSONObject json = null; 
     try { 
      json = array.getJSONObject(i); 
      superHero.setImageUrl(json.getString(ProductConfig.TAG_IMAGE_URL)); 
      superHero.setName(json.getString(ProductConfig.TAG_NAME)); 
      //superHero.setRank(json.getInt(ProductConfig.TAG_RANK)); 
      //superHero.setRealName(json.getString(ProductConfig.TAG_REAL_NAME)); 
      //superHero.setCreatedBy(json.getString(ProductConfig.TAG_CREATED_BY)); 
      //superHero.setFirstAppearance(json.getString(ProductConfig.TAG_FIRST_APPEARANCE)); 

      ArrayList<String> powers = new ArrayList<String>(); 

      JSONArray jsonArray = json.getJSONArray(ProductConfig.TAG_POWERS); 

      for (int j = 0; j < jsonArray.length(); j++) { 
       powers.add(((String) jsonArray.get(j)) + "\n"); 
      } 
      superHero.setPowers(powers); 


     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     listSuperHeroes.add(superHero); 
    } 
    //Finally initializing our adapter 
    adapter = new RecyclerViewDataAdapter(listSuperHeroes, this); 

    //Adding adapter to recyclerview 
    recyclerView.setAdapter(adapter); 



}

}

什么是崩溃报告？也发布堆栈跟踪。 – ajantha

发布logcat报告 –

尝试错误。使用这个过程非常简单，我认为即使你是初学者，也可以在网站上找到它。
