Android Facebook album photos request only returns

问题:

So i am trying to display facebook photos from an album in and Android app.

The problem i am having is if i call this:

facebookAsyncRunner.request(albumId + "/photos", new UserAlbumPhotosFetchListener(JSONResponse, photoView));

i get a JSONResponse of an array of 25 photos. However, i need more than just 25 photos... i need all of them in the album. So i tried calling this:

facebookAsyncRunner.request(albumId + "/photos?limit=50", new UserAlbumPhotosFetchListener(JSONResponse, photoView));

in an attempt to get 50 photos instead of 25. This did not work. Instead i got nothing. I also tried calling this same thing with limit=0, but this is giving me the same result. to be specific: JSONResponse.getJSONArray("data") = []

Does anyone have any idea of what is happening/ how to request more than just 25 photos from an album?

thanks!

EDIT: I found a solution!

Bundle params = new Bundle(); params.putString("limit", "10"); facebookAsyncRunner.request(albumId + "/photos", params, new UserAlbumPhotosFetchListener(JSONResponse, photoView));

I have posted an answer which integrates pagination for an Endless Scrolling List here:

It is too big to post all over again, so am linking to the original answer instead. The answer is literally a complete a solution on how to make a Facebook query to an Album, fetch all photos (limited initially with a limit=10) and then fetching additional photos from the album when the user has scrolled down to the end and adding them to the existing list of Photos already fetched.

It uses a GridView instead of a ListView but the logic remain the exact same.

Alternatively, if you are looking only for a way to fetch Photos, here is a far simpler solution to get you started.

try {
    String test = Utility.mFacebook.request("/10151498156121729/photos&access_token=YOUR_ACCESS_TOKEN?limit=1");
    Log.e("TEST", test);
} catch (Exception e) {
    // TODO: handle exception
}

The Album ID (10151498156121729) used in the code block above, is a Facebook Public Album.

I use the Utility class from the pre-3.0 Facebook SDK's HackBook example. If you are using the 3.0 SDK, I think you will need to substitute the Utility.mFacebook.request bit with an instance of the Facebook class

You should need to use Pagination for getting more than 25 photos. You can get only 25 items as result for a single query. To load the next 25 you should use the code like below:

facebookAsyncRunner.request(albumId + "/photos?offset=25&limit=25", new UserAlbumPhotosFetchListener(JSONResponse, photoView));

this will return the next 25 items, in this case the photos from 25th position to 50th position.

Try in this way.. Hope this may solve your problem.
