uploadActivity.java：-

public class ImageAdapter extends BaseAdapter
        {
        private Context context;

        public ImageAdapter(Context c)
        {
        // TODO Auto-generated method stub
        context = c;
        }

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

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

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

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

        LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);      

        if (convertView == null) {
        convertView = inflater.inflate(R.layout.list_upload, null);
        }


        // ColImgName
        TextView txtName = (TextView) convertView.findViewById(R.id.ColImgName);
        strPath = ImageList.get(position).toString();

        // Get File Name
        fileName = strPath.substring( strPath.lastIndexOf('/')+1, strPath.length() );
        File file = new File(strPath);
        @SuppressWarnings("unused")

        }
    } 

Answer 1

您需要回收位图对象。

    Bitmap bm = BitmapFactory.decodeFile(strPath);
    imageView.setImageBitmap(bm);

在get视图中完成以上代码行后，只需添加下面编写的代码///现在回收您的位图，这将在每次迭代时释放您的内存

    if(bm!=null)
   {
     bm.recycle();
     bm=null;
    }

在此之后，如果您得到相同的错误

替换下面的代码

    Bitmap bm = BitmapFactory.decodeFile(strPath);
    imageView.setImageBitmap(bm);

 final BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;

Bitmap bm = BitmapFactory.decodeFile(strPath,options);
imageView.setImageBitmap(bm);
