이 내 어댑터 클래스입니다

public class ImageAdapter extends BaseAdapter { 
    Context mcontext; 
    Integer Imageid[] = new Integer[] { R.drawable.image1, R.drawable.image3, 
      R.drawable.image4, R.drawable.image5, R.drawable.image6, 
      R.drawable.image2 }; 



    public ImageAdapter(Context context) { 
     // TODO Auto-generated constructor stub 
     super(); 
     this.mcontext = context; 
    } 

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

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

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

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 

     LayoutInflater inflater = (LayoutInflater) mcontext 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View gridView; 
     if(convertView == null){ 
      gridView = new View(mcontext); 

      gridView = inflater.inflate(R.layout.imageview,null); 

      ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView); 
      imageView.setImageResource(Imageid[position]); 
     } 
      else { 
       gridView = (View) convertView; 
      } 


     return gridView; 
    } 

} 

왜이 오류가? ..

감사합니다 사전에 :)

Answer 1

여기서 발생하는 것은 앱이 힙 크기를 벗어나므로 힙 크기에 해당하는 방식으로 이미지를 디코딩해야합니다. 어댑터에서이 코드를 사용하십시오.

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 

     LayoutInflater inflater = (LayoutInflater) mcontext 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View gridView; 
     if(convertView == null){ 
      gridView = new View(mcontext); 

      gridView = inflater.inflate(R.layout.imageview,null); 
      ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView); 

      BitmapFactory.Options options = new BitmapFactory.Options(); 
      options.inDither = false; 
      options.inJustDecodeBounds = false; 
      options.inPreferredConfig = Bitmap.Config.ARGB_8888; 
      options.inSampleSize = 3; 
      options.inPurgeable = true; 

      Bitmap icon = BitmapFactory.decodeResource(context.getResources(), 
        Imageid[position],options); 


      holder.imageView.setImageBitmap(icon); 
     } 
      else { 
       gridView = (View) convertView; 
      } 


     return gridView; 
    } 

Answer 2

사용중인 이미지가 큽니다.
