博客园app for xamarin android一款简洁阅读的博客园android客户端

碎碎念回顾2017 一款简洁阅读的博客园android客户端，采用xamarin android框架 c#语言、原生的android应用。 到了年底，坐在转椅上，望着窗外的雾霾......从16年6月走出校门，已经做了1年半的码农，成长不少，但总觉得进步得不够明显，虽然工资比刚来的时候涨了不少，但是还是觉得自己不够努力。也不知道是老板给的压力太少，还是自己给自己的目标定的太短。 打开qq企业邮箱，找到去年给老大发的年度总结和计划，十分惭愧，去年的计划几乎只完成了50%。 1.多线程编程理解和运用不够熟练； 2.javascript还是停留在万金油jquery上； 3.signalr的聊天室也没搞完成； 4.计划了很久用xamarin android写个博客园也是拖了好久才完工。 5.前端自适应还是停留在bootstrap上的基础，拿着标签就干。 6.设计模式也还没有深入学习 7.android进阶的东西也还没有看 8.收藏夹的文章快大半年了，都没仔细学习，可能这就是“松鼠症”吧 9.说要学习英语，学习英语的app倒是下载4个，每天最多也就打开一次，没办法英语基础还是很差！ 2018年的计划 前端自适应的学习 javascript面向对象编程 每天学习英语30分钟（可能感觉要黄） 完善自己的个人项目 c#设计模式的深入学习 webpack的掌握 维护个人博客（网站未做，服务器先行

Xamarin Tabbed Page Content Other than Tab

由 我是研究僧i 提交于 2021-02-11 15:52:32
问题 Quick question, In Xamarin Forms, when using a Tabbed Page, is there any way for there to be content that remains static between the tabs (other than the tabbar itself)? For example, if I have a TabbedPage with 3 children (say Page1 , Page2 and Page3 ), can I add other children to TabbedPage that are not a part of the tab itself, but elsewhere, and stay there between tabs? My use for this is I have 3 tabs in my TabbedPage , which is are at the bottom of the page. I would like a settings

How to securely authenticate users with Twitter on xamarin mobile apps?

由 佐手、 提交于 2021-02-11 15:48:22
问题 I would like to get a user id and user access token from Twitter in a Xamarin app. I would prefer to use a library if possible like Xamarin.Auth. There is a nice description here how to do it: https://mobileprogrammerblog.wordpress.com/2016/01/23/xamarin-android-twitter-authentication/ In short: var auth = new XA.OAuth1Authenticator( consumerKey: "CONSUMER_KEY", consumerSecret: "CONSUMER_SECRET", // THIS IS THE PROBLEM requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
