标记选择的用户为选中的FriendPicker（Facebook的SDK为Android） [英] Mark selected user as checked in FriendPicker (Facebook SDK for Android)

问题描述

我的的Facebook SDK为Android （尤其是显示好友的-tutorial ）。

我如何庆祝，我之前已经选择在PickerActivity当我点击显示友 - 按钮了吗？

How can I mark the selected users which i've selected before at the PickerActivity when i click on the "Show Friends"-button again?

推荐答案

您必须通过逗号分隔字符串选定的Facebook用户ID的捆绑到FriendPickerFragment。

You have to pass comma separated string with selected facebook user ids in the bundle to the FriendPickerFragment.

Bundle args = new Bundle();
args.putString("com.facebook.android.PickerFragment.Selection", "11111, 2222, 333, already selected facebook ids....");
friendPickerFragment = new FriendPickerFragment(args);

在列表中选择

在PickerFragment的onActivityCreated（），它会分析所选择的IDS节目。你可以看到在FacebookSDK以下code在PickerFragment。

In PickerFragment's onActivityCreated() it will parse the selected ids shows as selected in list. You can see the following code in PickerFragment in FacebookSDK.

selectionStrategy.readSelectionFromBundle(savedInstanceState, SELECTION_BUNDLE_KEY);
