I have a problem that I am showing images in grid view which is parsed from Url, I have designed a refine search dialog to refine the search in grid view but the problem is that parsing works fine but Grid view does not refreshed next time when I processed Refine Search. Means Grid View items does not refreshed it shows previous result. Please help me out for this Problem.

I haven’t check all your code, but I can see a few issues :
1.
Not sure what this is supposed to do, you create a new ImageAdapter, and then a second and call notifyDataSetChanged on it, which seems pretty useless as it isn’t binded to any view.
2. Your ImageAdapter class is broken, especially the getView method. The main idea behind getView is that you recieve a convertView to recycle. If it’s null, create a view and set the info in it. If it isn’t null, reuse the convertView and set the info in it. In your code, you only set the info if the view is null, so once you scroll or change the data it will try to recycle the views, and you won’t change their contents.
The method should be something like
You could also keep a reference to your adapter and call
notifyDataSetChangedwhen you want the GridView to refresh its contents.Last thing, you probably don’t want the getItemId method in your ImageAdapter to return 0 all the time, as the GridView uses that id to manage recycled views and all. An easier implementation would be
It might also be worth filling the getItem method.
