android-RequestBatch.Callback onBatchCompleted()未调用

概述发送一批请求时,无法使用Android的facebookgraphAPI库.运行此代码时未得到回调：RequestBatchrequestBatch=newRequestBatch(requests);requestBatch.addCallback(newcom.facebook.RequestBatch.Callback(){@Overridepublicv

发送一批请求时,无法使用Android的facebook graph API库.

运行此代码时未得到回调：

        RequestBatch requestBatch = new RequestBatch(requests);        requestBatch.addCallback(new com.facebook.RequestBatch.Callback() {            @OverrIDe            public voID onBatchCompleted(RequestBatch batch) {                Log.e(LOG_TAG, "onBatchCompleted()");            }        });        requestBatch.executeAsync();

解决方法:

找到了答案.

您需要为每个单独的请求设置回调以获取与批处理相关的回调,因为onBatchCompleted回调将在调用所有按请求的回调之后被调用.

        for (String frIEnd : frIEnds) {            MyLog.d(LOG_TAG, "Adding request for " + frIEnd.getInterestFbID());            String graPHPath = frIEnd + "/Feed";            Request request = new Request(session, graPHPath, null, httpMethod.GET);            Bundle params = new Bundle();            params.putString("fIElds",                             "ID,"+                             "name,"+                             "username,"+                             "Feed,");            request.setParameters(params);            // THIS IS VITAL OR THE BATCH CALLBACK WILL NEVER ARRIVE                        request.setCallback(new com.facebook.Request.Callback() {                @OverrIDe                public voID onCompleted(Response response) {}            });            requests.add(request);        }
