问题
I am using Volley Plus library. I am showing ListView with image and text view with no error, but when i scroll up and down lots of time in this listview it get OutOfMemoryError and crash the application.
Here is LogCat :

Here is my Adapter class :
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;
}
}
Please help me to get out from this problem.
回答1:
The problem is that you keep loading images but the memory they fill isn't released afterwards. You could simply if you are recycling a row test if the image is a bitmap and then call recycle() on it.
You might use something like this:
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();
}
回答2:
You should create SimpleImageLoader in onCreate() of Activity or some where else
DiskLruBasedCache.ImageCacheParams cacheParams = new DiskLruBasedCache.ImageCacheParams(mContext, "CacheDirectory");
cacheParams.setMemCacheSizePercent(0.5f);
SimpleImageLoader mImageFetcher = new SimpleImageLoader(mContext, null, cacheParams);
If you are still facing OOM exception then you can use NetworkImageView.
Detailed example is present in github sample

Here is the solution for this Problem with changes in Adapter class. In which i placed
DiskLruBasedCache.ImageCacheParams cacheParams = new DiskLruBasedCache.ImageCacheParams(mContext, "CacheDirectory");
cacheParams.setMemCacheSizePercent(0.5f);
SimpleImageLoader mImageFetcher = new SimpleImageLoader(mContext, null, cacheParams);
Inside if (rowView == null) which prevents to use above code repetitively in Adabpter Class.
