UI doesn't update until tap on the screen when setState is called inside a realm listener callback

阅读更多关于 UI doesn't update until tap on the screen when setState is called inside a realm listener callback

问题 UPDATED DESCRIPTION I have a listener on a Realm Object for getting updates. When there is an update on the server (or in the client) the function provided to the listener calls setState({}). The strange part is that even if the console says that everything is ok, and it shows that the render method was called with correct data, I can't see any updates to my app. If I tap on the screen randomly (after 1s,2s, 20s...) the UI magically updates and everything is correct. If I do the same setState

SVN服务器搭建详解--权限划分

阅读更多关于 SVN服务器搭建详解--权限划分

环境准备 SVN使用场景说明 svn说白了就是一种实现文件共享管理的软件，分成服务器端和客户端，所有的文件都存放在服务器端，每个人可以用客户端把文件取到本地查看，也可以在本地修改后上传到服务器端，这样大家就可以随时获得最新版的文件。 TortoiseSVN 就是最常用的一种SVN客户端软件。checkout的功能就是把服务器端的整个库取到本地来，checkout操作一般只需要用一次，完成checkout之后，再想获得最新版文件时，用的是update而不再需要checkout 这里使用CentOS7.3的阿里云服务器，需要关闭防火墙以及selinux。 [root@iZwz93cntl0pzsqbzlrghnZ ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) 查看当前YUM 源 [root@iZwz93cntl0pzsqbzlrghnZ ~]# ll /etc/yum.repos.d/ total 12 -rw-r--r-- 1 root root 675 Sep 17 22:45 CentOS-Base.repo -rw-r--r-- 1 root root 230 Sep 17 22:45 epel.repo -rw-r--r-- 1 root root 202 Sep 17 22:49

notifyDataSetChanged() not being called when underlying Realm is changed using RealmRecyclerViewAdapter

阅读更多关于 notifyDataSetChanged() not being called when underlying Realm is changed using RealmRecyclerViewAdapter

问题 I have a set of data in a Realm that is displayed in a RecyclerView using a RealmRecyclerViewAdapter . Basically, I'll have 25 elements displayed in the RecyclerView -- if items are being inserted into the Realm for the first time there are no issues. It seems to work properly if the Realm isn't being added to shortly after all its data has been deleted because the issue only arises when I need to delete all the items in the Realm and then add a new Collection of items shortly afterwards.
