Volley 加上列表适配器中的 OutOfMemoryError

我在用凌空加 https://github.com/DWorkS/VolleyPlus图书馆。我正在展示ListView图像和文本视图没有错误，但是当我在这个列表视图中上下滚动很多时间时，它得到OutOfMemoryError并使应用程序崩溃。

Here is LogCat :

这是我的适配器类：

public class ProductListAdapter extends BaseAdapter {

private Context mContext;
private List<Products> dataArray;

public ProductListAdapter(Context context, List<Products> d) {
    mContext = context;
    dataArray = d;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    View rowView = convertView;
    if (rowView == null) {
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView = inflater.inflate(R.layout.list_row_item_products, null);

        ViewHolder viewHolder = new ViewHolder();
        viewHolder.title = (TextView) rowView.findViewById(R.id.tvName);
        viewHolder.image = (ImageView) rowView.findViewById(R.id.list_image);

        rowView.setTag(viewHolder);
    }

    Products list;
    list = dataArray.get(position);

    ViewHolder holder = (ViewHolder) rowView.getTag();
    holder.title.setText(list.getName());

    DiskLruBasedCache.ImageCacheParams cacheParams = new DiskLruBasedCache.ImageCacheParams(mContext, "CacheDirectory");
    cacheParams.setMemCacheSizePercent(0.5f);
    SimpleImageLoader mImageFetcher = new SimpleImageLoader(mContext, null, cacheParams);
    mImageFetcher.get(list.getThumb(), holder.image);

    return rowView;
}

static class ViewHolder {
    TextView title;
    ImageView image;
}
}

请帮助我摆脱这个问题。

问题是您不断加载图像，但它们填充的内存随后并未释放。如果图像是位图，您可以简单地回收行测试，然后调用recycle()在上面。 你可能会使用这样的东西：

if (rowView == null) {
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView = inflater.inflate(R.layout.list_row_item_products, null);

        ViewHolder viewHolder = new ViewHolder();
        viewHolder.title = (TextView) rowView.findViewById(R.id.tvName);
        viewHolder.image = (ImageView) rowView.findViewById(R.id.list_image);

        rowView.setTag(viewHolder);
}
else {
    ViewHolder holder = (ViewHolder) rowView.getTag();
    if(holder.image.getDrawable() instanceof BitmapDrawable)
        ((BitmapDrawable) holder.image.getDrawable).getBitmap().recycle();
}
