Android Data-Binding实现原理 本文基于: androidx.databinding:databinding-runtime:3.4.1 一.Data-Binding简介 数据绑定库是一种支持库，借助该库，可以使用声明性格式（而非程序化地）将布局中的界面组件绑定到应用中的数据源。详细的文档介绍参考： https://developer.android.com/topic/libraries/data-binding 二.DataBinding原理 1. 示例 这个例子...
jetpack系列文章：Databinding源码分析（一）：单双向数据绑定
massonJ的博客

前言： 由于公司新项目使用MVVM模式，基于databinding的，因此专门分析了一下源码，有助于开发。之前项目用到的是MVP框架，其实MVP也能实现V和M的解耦，只是MVVM在解耦的基础上实现了V和M的双向绑定，达到自动更新同步数据，使开发更加便。 话不多说，开始分析，使用网上很多了，这里不说了： APT技术: databinding我们用起来很简单，越简单表示框架帮我们完成了越多的东西，毫无疑问自动生成的代码是通过apt技术完成的，这个我已经在Arouter源码分析中讲过了，这里附上链接，不再赘述：A

WPF学习之绑定—Validation Rule和Binding Group
码农

现在我们可以很容易的将业务数据作为源绑定到WPF控件并可以通过创建不同的Data Template后来以特定的样式展现。而作为这个最常用的功能我们可以通过Two Way的绑定模式与界面交互，而在这个时候我们就需要类似于ASP.NET中Validator一样的东西来限制或者说校验数据有效性。ValidationRule就是为这样的应用而生的。本文将详细讨论如何应用验证规则和自定义错误模板。 我们首

网络爬虫基于Python的豆瓣电影Top250数据采集：使用Requests与BeautifulSoup实现网页内容解析
12-03
内容概要：本文通过一个简单的Python爬虫实例，演示了如何使用requests库发送HTTP请求，获取豆瓣电影Top250页面的数据，并利用BeautifulSoup解析HTML内容，提取出中文电影名称。代码实现了基本的网页抓取与数据清洗流程，包括设置请求头模拟浏览器行为以应对简单反爬机制、解析响应文本以及过滤非中文片名，最终输出纯净的电影标题列表。; 适合人群：具备Python基础语法知识，对网络爬虫感兴趣的初学者或刚入门的数据采集学习者；适合学习Web数据获取的基本流程和技术栈。; 使用场景及目标：①学习如何使用requests发起网络请求并携带请求头信息；②掌握BeautifulSoup进行HTML结构化解析的方法；③理解网页内容提取与数据过滤的基本逻辑，为后续深入学习爬虫框架（如Scrapy）打下基础。; 阅读建议：建议读者在本地环境中配置好相关库（requests、BeautifulSoup），动手运行并调试代码，尝试修改选择器或目标网站以加深理解，同时注意遵守网站的robots协议，合理控制请求频率。
基于粒子群优化算法的p-Hub选址优化（Matlab代码实现）
12-03
内容概要：本文介绍了基于粒子群优化算法（PSO）的p-Hub选址优化问题的研究与实现，重点解决在考虑不确定性因素下的集群式物流或交通网络中枢纽节点（Hub）的选址优化问题。通过构建数学模型，结合Matlab编程实现粒子群算法对p-Hub选址问题进行求解，旨在最小化网络总体运输成本并提升系统效率。文章涵盖了问题建模、算法设计、参数设置及仿真结果分析全过程，展示了PSO在复杂组合优化问题中的应用能力。; 适合人群：具备一定运筹学、优化算法基础，熟悉Matlab编程，从事物流网络设计、智能算法研究或交通系统优化等相关领域的研究生、科研人员及工程技术人员。; 使用场景及目标：①掌握p-Hub选址问题的基本理论与建模范式；②学习如何基于粒子群优化算法的p-Hub选址优化（Matlab代码实现）将粒子群优化算法应用于实际网络优化问题；③通过Matlab代码实现理解智能优化算法的编码流程与调参技巧；④为物流、通信、航空等枢纽网络设计提供解决方案参考。; 阅读建议：建议读者结合文中提供的Matlab代码逐行理解算法实现细节，尝试调整参数或引入其他改进策略（如自适应权重、混合算法）以提升优化性能，同时可扩展至带容量约束、多分配或多目标的Hub选址问题进行深入研究。
