I have been able to pull the Facebook newsfeed for the logged in user using the "me/home" Graph API Call and am displaying the result in an activity.
Now I have been trying numerous methods which will query the post's like column and check if the current user has liked a post to display the status. Essentially, I am setting a drawable to indicate the user has liked a post.
I cannot really post any code that I have tried so far simply because none of them work. And believe me, I have tried literally numerous methods.
I would appreciate if someone could at least prod me in the right direction.
EDIT: This is my latest attempt at querying the likes column and comparing the result with the current user's ID:
This code is where I am checking for likes count and adding them to an ArrayList. This is also where I am running the query to get the likes on the post.
// GET THE POST'S LIKES COUNT
if (json_data.has("likes")) {
JSONObject feedLikes = json_data.optJSONObject("likes");
String countLikes = feedLikes.getString("count");
postLikesCountArrayList.add(countLikes);
// TEST STARTS
// QUERY THE LIKES COLUMN TO CHECK YOUR LIKE STATUS ON A POST
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, Utility.mFacebook.getAccessToken());
Utility.mAsyncRunner.request(finalThreadID + "/likes&limit=200", params, new LikesListener());
// TEST ENDS
} else {
String countLikes = "0";
postLikesCountArrayList.add(countLikes);
}
And this code block is the Listener (a privte class in the same activity) where the results are checked:
private class LikesListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
try {
JSONObject JOLikes = new JSONObject(response);
JSONArray JALikes = JOLikes.getJSONArray("data");
for (int i = 0; i < JALikes.length(); i++) {
JSONObject JOTemp = JALikes.getJSONObject(i);
if (JOTemp.has("id")) {
String getTempID = JOTemp.getString("id");
if (getTempID.equals(initialUserID)) {
Runnable run = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
ImageView postYourLike = (ImageView) findViewById(R.id.postYourLike);
postYourLike.setBackgroundResource(R.drawable.btn_icon_liked);
}
};
TestNewsFeeds.this.runOnUiThread(run);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
You can use this fql. Replace the post_id
SELECT likes.can_like, likes.user_likes FROM stream WHERE post_id = "1274834235_3976149403543"
response would look like this, if user_likes is true, he has liked it
{
"data": [
{
"likes": {
"can_like": true,
"user_likes": false
}
}
]
}

List exception error
try to replace lstListMobile.add(i, objMobileModal); with lstListMobile.add(objMobileModal);
when if (jsonObject.getString("email").equals(email)) condition fails 0 index is not added for that user.
you will get ArrayIndexOutOfBound error on lstListMobile.add(1, objMobileModal); if 0 index is not present
You're inserting lstListMobile.add(i, objMobileModal); maybe you can just add lstListMobile.add(objMobileModal);? Probably whats happening is that when i==0 is does not pass the test if (jsonObject.getString("email").equals(email)) {. So it does not add and the size remains 0. When i==1 it breaks when inserting.
Please check first array is not null
if (response.length > 0) {
// do something
}
else{
//empty array
}
I am trying to allow a user to login as a page with facebook - so if there's an easier way of doing it over what I'm trying, please feel free to tell me -
Currently, I log the user in with LoginManager and get the details of the user (i.e. their page and page access_token) using a GraphRequest. I then put the user's pages into a spinner so the user can select which page to post as (including their own).
Here's the problem. I have the access_token as a string from when the user logs in and I pull the information and I see the access_token when the user selects the page they want, but I'm totally unsure on how to set a new access token, especially from a string.
Here's the code I'm using:
GraphRequest requestPage = GraphRequest.newGraphPathRequest(
currentAccessToken,
"/me/accounts",
new GraphRequest.Callback() {
#Override
public void onCompleted(GraphResponse response) {
JSONArray jsonArray = null;
try {
jsonArray = response.getJSONObject().getJSONArray("data");
for(int i=0; i < jsonArray.length(); i++){
JSONObject page = jsonArray.getJSONObject(i);
String pageName = page.getString("name");
String pageToken = page.getString("access_token");
if(!pageName.equals("")) {
//I know there's a better way of getting the name and token together in an array, but I don't know how
pages_array.add(pageName);
pages_token_array.add(pageToken);
facebook_pages.setVisibility(View.VISIBLE);
} else {
pages_array.clear();
pages_token_array.clear();
}
}
} catch (JSONException e) {
e.printStackTrace();
}
final ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(StartPage.this, android.R.layout.simple_spinner_item, pages_array);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down view
spinnerArrayAdapter.notifyDataSetChanged();
page_spinner.setAdapter(spinnerArrayAdapter);
}
});
Bundle pageParameters = new Bundle();
pageParameters.putString("fields", "name,access_token,picture{url}");
requestPage.setParameters(pageParameters);
requestPage.executeAsync();
);
Then here's how I select the spinner
facebook_select_button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String spinner_value = page_spinner.getSelectedItem().toString();
int spinner_position = page_spinner.getSelectedItemPosition();
String newAccessToken = pages_token_array.get(spinner_position);
//AccessToken token = new AccessToken(newAccessToken);
//TODO: SET NEW ACCESS TOKEN
};
});
Like I said, I have the selection working and I can see the access token if I were to log it or Toast it on the button press. I just don't know how to CHANGE The access token.
Any ideas?
I succeed login and post my wall.

it look like works well.
first, pop up friends selector dialog,
and I clicked some friends, and click 'done' button.
it will call 'Callback' Funtion, and
debug.log(FBResult.text); show follow like this.

but now, I don't know how to use these values. T_T
I think FB.feed(); is well done. So,
I try to
for( int i=0; i<usernum; i++ )
{
FB.feed( "id[user_index]" , bula~bula );
}
but failed.
becuase, fbresult.text is not string!!?
I try to split this string(fbresult.text), to get "to":["userid1 number"], ["userid2 number"]
but I failed and disappointed.
please someone help me.
Anybody who has a good idea???
I really want to send my message(pic or message) to friend's facebook wall.
You can´t post to the wall of a friend anymore, since a very long time. In most (all?) cases this would be considered as spam, so they remove that possibility.
You can use the Send Dialog to send something to a friend, for example.
After making a call to the "me/home" Graph API, while parsing the JSON result, I am trying to make another query using FQL. The FQL query problem was solved in my earlier question.
The background of my implementation is: I am using a BaseAdapter and from the main activity, I am sending the data parsed from JSON using multiple ArrayLists. If I am not making the FQL query, everything is peachy. But when I introduce the FQL query, the query is always run after the adapter has been set to the ListView. This keeps causing the arrayindexoutofbound exception.
This is the code that I am using including the additional FQL query while parsing the JSON result. To keep the code short, I will include the relevant part as the rest works just fine. If more is needed, however, I will put that up too.
// GET THE POST'S LIKES COUNT
if (json_data.has("likes")) {
JSONObject feedLikes = json_data.optJSONObject("likes");
String countLikes = feedLikes.getString("count");
postLikesCountArrayList.add(countLikes);
// TEST STARTS
Runnable run = new Runnable() {
#Override
public void run() {
graph_or_fql = "fql";
String query = "SELECT likes.user_likes FROM stream WHERE post_id = \'"
+ finalThreadID + "\'";
Bundle params = new Bundle();
params.putString("method", "fql.query");
params.putString("query", query);
Utility.mAsyncRunner.request(null, params, new LikesListener());
}
};
TestNewsFeeds.this.runOnUiThread(run);
// TEST ENDS
} else {
String countLikes = "0";
postLikesCountArrayList.add(countLikes);
}
And this is the code for the LikesListener class. It is a private class declared in the same activity:
private class LikesListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
// Log.e("response", response);
try {
JSONArray JALikes = new JSONArray(response);
// Log.v("JALikes", JALikes.toString());
for (int j = 0; j < JALikes.length(); j++) {
JSONObject JOTemp = JALikes.getJSONObject(j);
// Log.e("JOTemp", JOTemp.toString());
if (JOTemp.has("likes")) {
JSONObject optJson = JOTemp.optJSONObject("likes");
// Log.v("optJson", optJson.toString());
if (optJson.has("user_likes")) {
String getUserLikeStatus = optJson.getString("user_likes");
Log.e("getUserLikeStatus", getUserLikeStatus);
arrayLikeStatus.add(getUserLikeStatus);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
I have figured out using debugging that the cause of the crash is the setAdapter being called before the second query completes. I see the log's being added to logcat after the crash has occured.
Any help on a solution for this is appreciated
UPDATE: Figured out the solution almost when I was about to give up.
SOLUTION
So instead of calling the BaseRequestListener as used in the question, this modification had to be made.
try {
graph_or_fql = "fql";
String query = "SELECT likes.user_likes FROM stream WHERE post_id = \'"
+ finalThreadID + "\'";
// Log.d("finalThreadID", finalThreadID);
Bundle params = new Bundle();
params.putString("method", "fql.query");
params.putString("query", query);
// Utility.mAsyncRunner.request(null, params, new LikesListener());
String fqlResponse = Utility.mFacebook.request(params);
// Log.e("fqlResponse", fqlResponse);
JSONArray JALikes = new JSONArray(fqlResponse);
// Log.v("JALikes", JALikes.toString());
for (int j = 0; j < JALikes.length(); j++) {
JSONObject JOTemp = JALikes.getJSONObject(j);
// Log.e("JOTemp", JOTemp.toString());
if (JOTemp.has("likes")) {
JSONObject optJson = JOTemp.optJSONObject("likes");
// Log.v("optJson", optJson.toString());
if (optJson.has("user_likes")) {
String getUserLikeStatus = optJson.getString("user_likes");
// Log.e("getUserLikeStatus", getUserLikeStatus);
arrayLikeStatus.add(getUserLikeStatus);
// Log.d("arrayLikeStatus", arrayLikeStatus.toString());
}
}
}
} catch (Exception e) {
// TODO: handle exception
}
Hope this helps someone save time if they are stuck like I was.
I want to show Facebook Page's Notes items with those comments and likes using Graph API.
To do that, I'm using the asyncFacebookRunner in Facebook SDK.
Steps are like this:
call asyncFacebookRunner.request to get Note Item with PageId
mAsyncRunner.request(sAPIString, new NotesRequestListener(), null);
Response has come. ( I can't highlight function call. Sorry for inconvenient to find it.)
public class NotesRequestListener implements com.facebook.android.AsyncFacebookRunner.RequestListener
{
/**
* Called when the request to get notes items has been completed.
* Retrieve and parse and display the JSON stream.
*/
#Override
public void onComplete(String response, Object state) {
// TODO Auto-generated method stub
Log.i("My_TAG", "onComplete with response, state");
try
{
// process the response here: executed in background thread
final JSONObject json = new JSONObject(response);
JSONArray arrNotesItems = json.getJSONArray("data");
int l = (arrNotesItems != null ? arrNotesItems.length() : 0);
// !!!!
// This has another request call
// !!!!
final ArrayList<WordsItem> newItems = WordsItem.getWordsItems(arrNotesItems,getActivity());
WordsActivity.this.runOnUiThread(new Runnable() {
public void run() {
wordsItems.clear();
wordsItems.addAll(newItems);
aa.notifyDataSetChanged();
}
}); // runOnUiThread
} // try
catch (JSONException e)
{
Log.i("My_TAG", "JSON Error in response");
} // catch
} // onComplete
... other override methods ...
} // Request Listener
< Another Class >
public static ArrayList<WordsItem> getWordsItems(JSONArray arrJSON, Activity activity) {
ArrayList<WordsItem> wordsItems = new ArrayList<WordsItem>();
int l = (arrJSON != null ? arrJSON.length() : 0);
try {
WordsItem newItem;
for (int i=0; i<l; i++) {
JSONObject jsonObj = arrJSON.getJSONObject(i);
String sTitle = jsonObj.getString("subject");
String sNoteID = jsonObj.getString("id");
... get another fields here ...
newItem = new WordItem(...);
// !!!!
// This has request call for comments
// !!!!
ArrayList<CommentItem> arrComment = getUserComments(sNoteID);
wordsItems.add(newItem);
}
} catch (Exception e) {
e.printStackTrace();
}
return wordsItems;
} // getWordsItems
call another asyncFacebookRunner.request to get comments of item(with NoteID)
in getUserComments
mAsyncRunner.request(sAPIString, new CommentRequestListener(), null);
Before getting comments(OnComplete in CommentRequestListener has not called), getWordsItems returns item array.
So I can't see the comments.
How can I wait to update UI till getting comments?
(It's so ironic to synchronize asynchronized calls.)
Thanks in advance.
Use facebook object which has non-asynchronous request method.
You need not implement listener method.
So, I suggest below means.
use mAsyncRunner.request for first request call.
use mFacebookRunner.request for second request call.
I hope it may help you:-)
Using FQL - Facebook Query Language you can easily get all this information about any particular note info
, Also to get likes on that and comments over it as like examples given in the links.
