picasso android Bild nicht geladen

Question

Ich versuche, Bilder von einer API zu bekommen, und ich habe Code geschrieben, aber Bilder werden nicht geladen in Emulator

Haupttätigkeit

public class MainActivity extends ListActivity { 

    List<Flower> flowerList; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final RestAdapter restadapter = new RestAdapter.Builder().setEndpoint("http://services.hanselandpetal.com").build(); 

     api flowerapi = restadapter.create(api.class); 

     flowerapi.getData(new Callback<List<Flower>>() { 
      @Override 
      public void success(List<Flower> flowers, Response response) { 
       flowerList = flowers; 
       adapter adapt = new adapter(getApplicationContext(),R.layout.item_file,flowerList); 
       setListAdapter(adapt); 
      } 

      @Override 
      public void failure(RetrofitError error) { 
       Toast.makeText(getApplicationContext(),"Failed",Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 

Im Paket Modell Ich habe Blumen Klasse

public class Flower { 

    private int productId; 
    private String name; 
    private String category; 
    private String instructions; 
    private double price; 
    private String photo; 
    private Bitmap bitmap; 

    public Flower() { 
    } 

    public Bitmap getBitmap() { 
     return bitmap; 
    } 

    public void setBitmap(Bitmap bitmap) { 
     this.bitmap = bitmap; 
    } 

    public String getCategory() { 
     return category; 
    } 

    public void setCategory(String category) { 
     this.category = category; 
    } 

    public String getInstructions() { 
     return instructions; 
    } 

    public void setInstructions(String instructions) { 
     this.instructions = instructions; 
    } 

    public String getName() { 
     return name; 
    } 

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

    public String getPhoto() { 
     return photo; 
    } 

    public void setPhoto(String photo) { 
     this.photo = photo; 
    } 

    public double getPrice() { 
     return price; 
    } 

    public void setPrice(double price) { 
     this.price = price; 
    } 

    public int getProductId() { 
     return productId; 
    } 

    public void setProductId(int productId) { 
     this.productId = productId; 
    } 

}

Im Netzwerk-Paket Ich habe api Java-Klasse

public interface api { 
    @GET("/feeds/flowers.jason") 
    public void getData(Callback<List<Flower>>response); 
} 

Und dann habe ich adaptor java class

public class adapter extends ArrayAdapter<Flower> { 

    String url="http://services.hanselandpetal.com/photos/"; 
    private Context context; 
    private List<Flower> flowerList; 
    public adapter(Context context, int resource, List<Flower> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     this.flowerList = objects; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     View view = inflater.inflate(R.layout.item_file,parent,false); 
     Flower flower = flowerList.get(position); 
     TextView tv = (TextView) view.findViewById(R.id.name); 
     tv.setText(flower.getName()); 
     ImageView img = (ImageView) view.findViewById(R.id.img); 
     Picasso.with(getContext()).load(url+flower.getPhoto()).resize(100,100).into(img); 
     return view; 
    } 
}
