インテントを使ってcardviewからピカソで別のアクティビティに画像を渡す方法

Question

cardviewから「DetailActivity」という別のアクティビティにtextviewデータを渡すことができますが、DetailAtivityに画像を渡す方法もわかりませんインテントを使用してアイテムの説明を送信する場合のように、ビューホルダクラスにない他のデータを送信できますか？ここで

は以来、私のDetailActivity

public class DetailActivity extends AppCompatActivity { 
TextView nameTxt,catTxt,availTxt,priceTxt; 
ImageView imageLogo; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_detail); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setDisplayShowHomeEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    nameTxt = (TextView) findViewById(R.id.titleTxt); 
    imageLogo = (ImageView) findViewById(R.id.imagelogo); 
    catTxt= (TextView) findViewById(R.id.catTxt); 
    availTxt = (TextView) findViewById(R.id.availTxt); 
    priceTxt = (TextView) findViewById(R.id.pricesTxt); 
    //GET INTENT 
    Intent i=this.getIntent(); 
    //RECEIVE DATA 
    String title=i.getExtras().getString("TITLE_KEY"); 
    String cat=i.getExtras().getString("CAT_KEY"); 
    String avail=i.getExtras().getString("AVAIL_KEY"); 
    String price=i.getExtras().getString("PRI_KEY"); 
    //here // String image=i.getExtras().getString("LOGO_KEY"); 
    //BIND DATA 
    nameTxt.setText(title); 
    catTxt.setText(cat); 
    availTxt.setText(avail); 
    priceTxt.setText(price); 
    // here// Picasso.with(DetailActivity.this).load(image).into(imageLogo); 

} 

}

大丈夫、私のviewholderクラスここ

public static class FoodViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

    TextView tvFoodName; 
    RatingBar ratingBar; 
    ImageView ivFoodPoster; 
    TextView tvFoodCategory; 
    TextView tvFoodAvailableUpto; 
    TextView tvFoodPrice; 
    ImageView ivNextArrow; 
    ItemClickListener itemClickListener; 

    public FoodViewHolder(View v) { 
     super(v); 
     tvFoodName = (TextView) v.findViewById(R.id.tvName); 
     ratingBar = (RatingBar) v.findViewById(R.id.rating_bar); 
     ivFoodPoster = (ImageView) v.findViewById(R.id.imgThumb); 
     tvFoodCategory = (TextView) v.findViewById(R.id.tvCategory); 
     tvFoodAvailableUpto= (TextView) v.findViewById(R.id.tvavailable); 
     tvFoodPrice = (TextView) v.findViewById(R.id.tvprice); 
     ivNextArrow = (ImageView) v.findViewById(R.id.NextArrow); 




     v.setOnClickListener(this); 
    } 
    public void setItemClickListener(ItemClickListener itemClickListener) 
    { 
     this.itemClickListener=itemClickListener; 
    } 
    @Override 
    public void onClick(View view) { 
     this.itemClickListener.onItemClick(this.getLayoutPosition()); 
    } 
} 

私FirebaseAdapterここ

FirebaseRecyclerAdapter<Food,FoodViewHolder> adapter = new FirebaseRecyclerAdapter<Food, FoodViewHolder>(
      Food.class, 
      R.layout.food_item, 
      FoodViewHolder.class, 

      //referencing the node where we want the database to store the data from our Object 
      mDatabaseReference.child("users").child(userId).child("food").getRef() 
    ) { 


     @Override 
     protected void populateViewHolder(final FoodViewHolder viewHolder, final Food model, int position) { 
      if(tvNoMovies.getVisibility()== View.VISIBLE){ 
       tvNoMovies.setVisibility(View.GONE); 
      } 
      viewHolder.tvFoodName.setText(model.getFoodName()); 
      viewHolder.ratingBar.setRating(model.getFoodRating()); 
      viewHolder.tvFoodCategory.setText(model.getFoodCategory()); 
      viewHolder.tvFoodAvailableUpto.setText(model.getFoodAvailableUpto()); 
      viewHolder.tvFoodPrice.setText(model.getFoodPrice()); 
      Picasso.with(getActivity().getApplicationContext()).load(model.getFoodPoster()).into(viewHolder.ivFoodPoster); 

      viewHolder.setItemClickListener(new ItemClickListener() { 
       @Override 
       public void onItemClick(int pos) { 
        //OPEN DETAI ACTIVITY 
        Intent i = new Intent(getContext(), DetailActivity.class); 
        i.putExtra("TITLE_KEY",viewHolder.tvFoodName.getText().toString()); 
        i.putExtra("CAT_KEY",viewHolder.tvFoodCategory.getText().toString()); 
        i.putExtra("AVAIL_KEY",viewHolder.tvFoodAvailableUpto.getText().toString()); 
        i.putExtra("PRI_KEY",viewHolder.tvFoodPrice.getText().toString()); 
        here // i.putExtra("LOGO_KEY",viewHolder.ivFoodPoster); 

        getContext().startActivity(i); 
       } 
      }); 

     } 

    }; 
    mRecyclerView.setAdapter(adapter); 

されていますのリターンは、あなたがそれを行うことができますString：

i.putExtra("IMAGE_KEY",model.getFoodPoster()); 

Iを約読むことをお勧めだろうしかし：serializableかparcelable（推奨）、それらのいずれかを使用して、あなたが別のアクティビティにオブジェクト全体modelを送らせます！コメント（ `// //ここ`）コードと間違っている何
