Java Android Facebook SDK使用OnSelectionChangeListener获取选定用户时出现问题

Im使用的格式与Facebook SDK示例在其代码中显示的格式相同

    friendPickerFragment.setOnSelectionChangedListener(new PickerFragment.OnSelectionChangedListener() {
        @Override
        public void onSelectionChanged(PickerFragment<?> fragment){
            FriendPickerApplication application = (FriendPickerApplication) getApplication();
            application.setSelectedUser(friendPickerFragment.getSelection());

        }

并将selectedUser定义为

private GraphUser selectedUser;

问题出在application.setSelectedUser中 它返回错误“FriendPickerApplication类型中的方法setSelectedUser（GraphUser）不适用于参数（List GraphUser）”

---

setSelectedUser显然不需要列表。如何修复此问题？

friendPickerFragment.getSelection（）返回列表。 检查

试试这个

public void setSelectedUser(ListGraphUser selectedUser) {
    this.selectedUser = selectedUser;
}

private ListGraphUser selectedUser;

public void setSelectedUser(ListGraphUser selectedUser) {
    this.selectedUser = selectedUser;
}

private ListGraphUser selectedUser;
