在加載15圖像時出現18662412字節的分配錯誤內存不足

我要通過recyclerview在CardView中顯示圖像。有15張圖片共15毫克大小。當我在genymotion模擬器（定製手機4.1.1 Api16規範）上運行應用程序時，出現內存不足錯誤。錯誤是在這條線：在加載15圖像時出現18662412字節的分配錯誤內存不足

foodViewHolder.txtImage.setImageResource(food.getConverted_image());

這是我的適配器

package com.example.android.dezcook; 

import android.content.Context; 
import android.media.Image; 
import android.support.v7.widget.RecyclerView; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.TextView; 

import com.squareup.picasso.Picasso; 

import org.w3c.dom.Text; 

import java.io.IOException; 
import java.util.List; 

/**

public class Food_Adapter extends RecyclerView.Adapter<Food_Adapter.foodViewHolder>{ 
    private List<Food> foodList; 
    private Context context; 
    public Food_Adapter(List<Food> foodList,Context context) 
    { 
     this.foodList=foodList; 
     this.context=context; 
    } 
    @Override 
    public foodViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { 
     View itemView= LayoutInflater.from(viewGroup.getContext()). 
       inflate(R.layout.card_layout,viewGroup,false); 
     return new foodViewHolder(itemView); 
    } 

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

    @Override 
    public void onBindViewHolder(foodViewHolder foodViewHolder, int i) { 
     Food food=foodList.get(i); 
     foodViewHolder.txtName.setText(food.getTxtName()); 
     foodViewHolder.txtItems.setText(food.getItems()); 
     foodViewHolder.txtId.setText(Integer.toString(food.getTxtid())); 


     foodViewHolder.txtImage.setImageResource(food.getConverted_image()); 




    } 
//food.getTxtImage() 


    public static class foodViewHolder extends RecyclerView.ViewHolder { 

     protected TextView txtName; 
     protected TextView txtItems; 
     protected ImageView txtImage; 
     protected TextView txtId; 

     public foodViewHolder(View v) { 
      super(v); 
      txtName=(TextView)v.findViewById(R.id.txtName); 
      txtItems=(TextView)v.findViewById(R.id.txtItems); 
      txtImage=(ImageView)v.findViewById(R.id.card_thumbnail); 
      txtId=(TextView)v.findViewById(R.id.txtid); 

     } 
    } 


}

我出示該卡的方式：

public void show_card() 
    { 
     RecyclerView reclist=(RecyclerView)findViewById(R.id.cardList); 
     reclist.setHasFixedSize(true); 
     LinearLayoutManager llm=new LinearLayoutManager(this); 
     llm.setOrientation(LinearLayoutManager.VERTICAL); 
     reclist.setLayoutManager(llm); 
     Food_Adapter fa=new Food_Adapter(Configure_bank(),this); 
     reclist.setAdapter(fa); 
    }

和我的名片佈局XML

15MB？它們在內存中可能會更大，尤其是在自動縮放發生的情況下。 –

18662412〜2160x2160圖片....爲什麼你需要這麼大的圖像？ ... @SamiKuhmonen寫道...磁盤上的大小並不重要，位圖總是採用'W * H * pixelSize'（其中像素大小通常爲（ARGB_8888）爲4個字節） – Selvin

我需要以最高質量 – Jumong

使用畢加索庫，通過在磁盤上的gradle這個依賴加入這個
compile 'com.squareup.picasso:picasso:2.5.2'

Picasso 
.with(getActivity()) 
.load(mostPopular) 
.get("your_image") 
.fit() 
.into("your_imageview");

你真的沒有需要這樣大小的圖像。只需使用Picasso加載和調整圖像大小，例如：

public void onBindViewHolder(final ImageViewHolder holder, int position) { 
    Picasso.with(context) 
      .load(itemList.get(position).getLink()) 
      .error(R.drawable.error_image) 
      .placeholder(R.drawable.progress_animation) 
      .into(holder.image); 
      .into(new Target() { 
       @Override 
       public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { 
        int targetWidth = parentWidth/2; 
        float ratio = (float) bitmap.getHeight()/(float) bitmap.getWidth(); 
        float heightFloat = ((float) targetWidth) * ratio; 

        final android.view.ViewGroup.MarginLayoutParams layoutParams 
          = (ViewGroup.MarginLayoutParams) holder.image.getLayoutParams(); 

        layoutParams.height = (int) heightFloat; 
        layoutParams.width = (int) targetWidth; 
        holder.image.setLayoutParams(layoutParams); 
        holder.image.setImageBitmap(bitmap); 
       } 

       @Override 
       public void onBitmapFailed(Drawable errorDrawable) { 
       } 

       @Override 
       public void onPrepareLoad(Drawable placeHolderDrawable) { 
       } 
      }); 
}

因此，您可以擺脫OutOfMemory問題。

圖像位於資源文件夾（txtImage.setImageResource）中，而不是來自URL，最好仔細查看問題。 – Neo

@Neo和？畢加索也可以從資源加載圖像調整大小... – Selvin

@亞歷山大我認爲不需要「'.into（新目標（）{...}）'」，因爲畢加索會自動調整大小以適應ImageView – Selvin
