android - 使用 Facebook sdk 3.0.1 Android 为 facebook 好友列表实现分页

Question

我想逐页获取Facebook好友。可以吗？

Answer 1

实现分页的最佳方式：当您获得第一个响应时，从 Response 对象中检索下一页 Request 对象。然后在您想要获取下一页数据时执行该请求

Response response = yourFirstRequest.executeAndWait(); //getRequestForPagedResults() returns null if there is no more paging, you can get previous page request with parameter PagingDirection.PREVIOUS Request nextPageRequest = response.getRequestForPagedResults(PagingDirection.NEXT);

//当你想要下一页信息之后

nextPageRequest.executeAndWait();

Answer 2

在 facebook graph api 中试试这个

https://graph.facebook.com/me/friends?limit=1

    Bundle params = new Bundle();
    params.putString("limit",  "1");
    Request tagRequest = new Request(Session.getActiveSession(), me/friends, params, HttpMethod.GET, new Request.Callback() {

    @Override
    public void onCompleted(Response response) {
        //here you can get your friends in json data. and also "paging" with "next" tag.
    GraphObject graphObject = response.getGraphObject();
    JSONObject jsonObject = graphObject.getInnerJSONObject();
        String next = jsonObject.getJSONObject("paging").getString("next");
}
//for next friend
// before using next remove the graph api path from it. i.e  "https://graph.facebook.com/"
    Request.executeGraphPathRequestAsync(Session.getActiveSession(), next, new Request.Callback() {

    @Override
    public void onCompleted(Response response) {}
