前端函数:
@Override
public void onTrendRefresh(final GeneralTrendFragment fragment, int trend_type) {
Map<String, Integer> params = new HashMap<>();
params.put("lastTime", 0);
AVCloud.callFunctionInBackground("fetchNewPostFour", params, new FunctionCallback<ArrayList<AVObject>>() {
@Override
public void done(ArrayList<AVObject> object, AVException e) {
fragment.finishRefresh();
if (e == null && object != null) {
// ArrayList<AVObject> list = (ArrayList<AVObject>) object;
Log.d(TAG, "done: size: " + object.size());
Log.d(TAG, "done: " + object.toString());
} else {
GeneralUtil.showToast("获取失败");
if (e != null) {
Log.d(TAG, "done: call error: " + e.toString());
}
}
}

}
根据调试结果，返回的数组为null
