列表視圖適配器中的java.lang.outofmemoryerror異常

Question

我的列表視圖適配器出現問題。在這裏我的源代碼如下的適配器：

public class ListItemAdapter extends BaseAdapter { 
     private static ArrayList<ItemDetail_class> DataProcessorResult; 
     private LayoutInflater myInflater; 
     Context mycontext; 

     public ListItemAdapter(Context context, ArrayList<ItemDetail_class> results) { 
      DataProcessorResult = results; 
      myInflater = LayoutInflater.from(context); 
     } 

     @Override 
     public int getCount() { 
      // TODO Auto-generated method stub 
      return DataProcessorResult.size();  
     } 

     @Override 
     public Object getItem(int position) { 
      // TODO Auto-generated method stub 
      return DataProcessorResult.get(position); 
     } 

     @Override 
     public long getItemId(int position) { 
      // TODO Auto-generated method stub 
      return position; 
     } 

     @Override 
     public View getView(final int position, View convertView, ViewGroup parent) { 
      ViewHolder holder; 
      final Context mycontext=parent.getContext(); 

      if(convertView == null) { 
       convertView = myInflater.inflate(R.layout.custom_view_item, null); 
       holder = new ViewHolder(); 
       holder.tvitemcode = (TextView) convertView.findViewById(R.id.tvitemcode); 
       holder.tvitemname = (TextView) convertView.findViewById(R.id.tvitemname); 
       holder.tvsize = (TextView) convertView.findViewById(R.id.tvsize); 
       holder.tvprice = (TextView) convertView.findViewById(R.id.tvprice);      
       holder.imgitem= (ImageView) convertView.findViewById(R.id.imgitem); 
       holder.imgview= (ImageView) convertView.findViewById(R.id.imgview); 

       convertView.setTag(holder);    
      }else{ 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      holder.tvitemcode.setText(DataProcessorResult.get(position).getItemCode()); 
      holder.tvitemname.setText(DataProcessorResult.get(position).getItemName()); 
      holder.tvsize.setText(DataProcessorResult.get(position).getSize()); 
      holder.tvprice.setText(DataProcessorResult.get(position).getPrice()); 

      holder.tvitemcode.setTextSize(TypedValue.COMPLEX_UNIT_PX, mycontext.getResources().getDimensionPixelSize(R.dimen.lbllistviewitem)); 
      holder.tvitemname.setTextSize(TypedValue.COMPLEX_UNIT_PX, mycontext.getResources().getDimensionPixelSize(R.dimen.lbllistviewitem)); 
      holder.tvsize.setTextSize(TypedValue.COMPLEX_UNIT_PX, mycontext.getResources().getDimensionPixelSize(R.dimen.lbllistviewitem)); 
      holder.tvprice.setTextSize(TypedValue.COMPLEX_UNIT_PX, mycontext.getResources().getDimensionPixelSize(R.dimen.lbllistviewitem)); 

      String imgName = DataProcessorResult.get(position).getItemCode(); 
      imgName=(imgName.replace("-","")); 
      imgName=imgName.toLowerCase(); 
      int imgID=0; 
      holder.imgitem.getLayoutParams().width= mycontext.getResources().getDimensionPixelSize(R.dimen.photolistviewitem); 
      holder.imgitem.getLayoutParams().height= mycontext.getResources().getDimensionPixelSize(R.dimen.photolistviewitem); 

      if (mycontext.getResources().getIdentifier(imgName+"_1", "drawable", mycontext.getPackageName())==0) 
      { 
       String imagepath = Environment.getExternalStorageDirectory() + "/Asiades/"+imgName+".jpg"; 
       File FileMain = new File(imagepath); 
       if (FileMain.exists()){ 
        BitmapFactory.Options options = new BitmapFactory.Options(); 
        options.inPreferredConfig = Bitmap.Config.ARGB_8888; 
        options.inSampleSize = 8; 
        Bitmap bitmap = BitmapFactory.decodeFile(imagepath, options);   
        holder.imgitem.setImageBitmap(bitmap);   
       }else{ 
        imgID = mycontext.getResources().getIdentifier("blankitem", "drawable", mycontext.getPackageName()); 
        holder.imgitem.setImageResource(imgID); 
       }      
      }else { 
       imgID = mycontext.getResources().getIdentifier(imgName+"_1", "drawable", mycontext.getPackageName()); 
       holder.imgitem.setImageResource(imgID);   
      }  

      holder.imgview.getLayoutParams().width= mycontext.getResources().getDimensionPixelSize(R.dimen.arrowicon); 
      holder.imgview.getLayoutParams().height= mycontext.getResources().getDimensionPixelSize(R.dimen.arrowicon); 

      holder.imgview.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        OtherClass.setItemCode(DataProcessorResult.get(position).getItemCode()); 
        Intent MyIntent=new Intent(mycontext, ViewDetailItem.class);          
        mycontext.startActivity(MyIntent); 
       } 
      }); 

      if (position % 2 == 1) {convertView.setBackgroundColor(Color.WHITE);} else {convertView.setBackgroundColor(Color.rgb(208,212,208)); }   
      return convertView; 
     } 

     static class ViewHolder { 
      TextView tvitemcode; 
      TextView tvitemname; 
      TextView tvsize; 
      TextView tvprice; 
      ImageView imgitem; 
      ImageView imgview; 
     } 

    } 

這裏我logcat的錯誤： 10-30 00：12：38.370：E/AndroidRuntime（22719）：在android.content.res.Resources.loadDrawable（資源。 java：3022） 10-30 00：12：38.370：E/AndroidRuntime（22719）：at android.content.res.Resources.getDrawable（Resources.java:1586） 10-30 00：12：38.370：E/AndroidRuntime（22719）：在android.widget.ImageView.resolveUri（ImageView.java:648） 10-30 00：12：38.370：E/AndroidRuntime（22719）：at android.widget.ImageView.setImageResource（ImageView.java： 377）

有人可以幫我解決這個問題會徽？非常感謝您的支持

您無法在UI線程上加載這些圖像。您需要使用AsyncTask或image loading library。
