新的：
最后我得到了一些解决方案.它的工作对我很好.如有任何建议,请通知我.
我的新代码在这里. (它使用堆栈与生产者消费者patern和bacground线程进行)

@覆盖
public void bindView(View view,Context context,Cursor cursor){

ViewHolder holder = (ViewHolder) view.getTag();
    String name = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.TITLE));
    int id = cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID));
    holder.getIdView().setText(name);
    holder.getThumbView().setTag((Integer)id);
    if(LazyLoader.getInstance().containsKey(id)) {
        Object bitmap = LazyLoader.getInstance().getBitMap(id);
        if(null != bitmap && (bitmap instanceof  Bitmap)) {
            holder.getThumbView().setImageBitmap((Bitmap)bitmap);
