Android开发架构思考及经验总结（下）

阅读更多关于 Android开发架构思考及经验总结（下）

前言架构设计，到底是什么呢？基于这段时间的学习和自己的一些思考，我认为架构是基于产品和技术所达成的一种共识。我不是专业的架构师，也不是经验老道的开发者。本文目的有三，一是整理这段时间的架构学习和思考以及总结这一年的开发经验教训，二是希望能够与各位朋友探讨移动端App的架构设计，三是希望我们每一个应用开发者能够拥有架构的意识。个人的水平有限，诸多不对的地方，恳请批评指正。提示：文中链接需要点击文章末尾处阅读原文才能点击。零、知识大纲提示请先阅读《Android开发架构思考及经验总结（上）》五、技术前面啰嗦了很多，终于写到这里了。对于一个开发人员来说，怎么做才是我们的关键问题所在。只会Android开发，所以以下只讨论Android。我主要从以下几个方面来谈一谈怎么做这个问题。 1、技术选型（1）、开发平台移动端的开发目前主要是两大阵营Android、IOS,其他的就不多说了。（2）、开发工具编译工具:Eclipse&Ant、AndroidStudio&Gradle，作为Android开发者，目前毫无疑问应该选择AndroidStudio&Gradle; 代码仓库：Git 、SVN ,工具有海龟、AndroidStudio也集成了VCS； Maven仓库：可以使用nexus创建自己的maven私服；持续集成：Jinkens、Buildbot

阅读更多关于 Kendo MVVM create new record with remote datasource

问题 I think I'm missing something simple, but I can't find any examples showing how to do this... also, please forgive me if some of the terminology I'm using is wrong. I simply want to use an HTML form that is bound to a Kendo Observable object to create a new record in my remote datasource. All the examples I've seen show how to edit existing records, but that's not what I'm looking for (at least not at the moment). I've created a Fiddle http://jsfiddle.net/matbeard/fYfYz/2/ with a simple cut

阅读更多关于 How to use a FolderBrowserDialog from a WPF application with MVVM

问题 I'm trying to use the FolderBrowserDialog from my WPF application - nothing fancy. I don't much care that it has the Windows Forms look to it. I found a question with a suitable answer (How to use a FolderBrowserDialog from a WPF application), except I'm using MVVM. This was the answer I "implemented", except I can't get the window object and I'm just calling ShowDialog() without any parameters. The problem is this: var dlg = new FolderBrowserDialog(); System.Windows.Forms.DialogResult result
