很酷的导航条下拉效果

WPF 进度条ProgressBar

今天研究了一下wpf的进度条ProgressBar 1.传统ProgressBar WPF进度条ProgressBar 这个控件,如果直接写到循环里,会死掉,界面会卡死,不会有进度.需要把进度条放到单独的线程中. 传统的需要建立 Thread 或者使用 Timer,分别写在不同的方法中.但现在,使用 Dispatcher.Invoke 调用可以实现这个目的. for (int i = 0; i <= 10000; i++)            {                double v

WPF进度条系列②旋转小圆圈

 写在之前: 关于WPF的样式,我也是学习了很多朋友的文章才有了下面的东西,因为时间有些久远 & 备份的链接也都不在了. 所以,究竟是看过哪些文章,也是记不清楚了…… 请见谅. --------------------------------我是害羞的分割线----------------------------------- 旋转小圆圈进度条见效果: xaml: <UserControl x:Class="AppHost.ProbarRotate" xmlns=&quo

JQ-滚动条下拉无限的加载数据

一.原理 利用滚动的高度,如果滚动的高度到达一定范围,就加载数据 二.实现 利用$(document.body).outerWidth()获取的是屏幕的高度,这个是固定的,不变的 利用$(window).scrollTop()获取您滚动的高度 利用$(document).height()获取总的高度 注:$(widnow).height()这个是可视区的高度,这个跟$(document).height()很容易混淆 三.上代码 <section> <div id="tishi&

React实现顶部固定滑动式导航栏（导航条下拉一定像素时显示原导航栏样式）

摘要 基于react的框架开发一个顶部固定滑动式的酷炫导航栏,当导航栏置顶时,导航栏沉浸在背景图片里:当鼠标滑动滚轮时,导航栏固定滑动并展示下拉样式. HTML部分 相关技术栈:react.antd.react-router.详细的技术栈应用请参考官方文档的使用说明. * 展示主页App.jsx组件代码 import React from 'react'; import './App.css'; import { Link, Route } from 'react-router-dom'; im

Photoshop和WPF双剑配合，打造炫酷个性的进度条控件

现在如果想打造一款专业的App,UI的设计和操作的简便性相当重要.UI设计可以借助Photoshop或者AI等设计工具,之前了解到WPF设计工具Expression Blend可以直接导入PSD文件或者AI设计文件(当然不是全部特征支持),最近研究了一下,也废了一番周折,好在最后实现了预期的效果.下面将step by step用示例说明如何先用PS构建一个矢量图形模板,然后用Expression Blend导入PSD文件,并获取PATH的Data值,为打造一款炫酷的个性进度条控件构建美观UI.

支持下拉刷新和上划加载更多的自定义RecyclerView（仿XListView效果）

首先看效果 下拉刷新:        上划加载        在项目更新的过程中,遇到了一个将XListView换成recyclerView的需求,而且更换完之后大体效果不能变,但是对于下拉刷新这样的效果,谷歌给出的解决方案是把RecyclerView放在一个SwipeRefreshLayout中,但是这样其实是拉下一个小圆形控件实现的,和XListView的header效果不同.在网上找了很多的别人代码,都没有实现我想要的效果,于是自己动手写了一个. 具体实现的效果有以下几条 下拉刷新功能:

2019如何刷百度电脑下拉框？

如何刷百度下拉框? 巧推网业务主要是快速排名和下拉框排名,今天小编给大家说说百度下拉框排名是怎么刷,以及效果如何?下面先看看我们给自己刷的几个案例: 以上是2个百度电脑端下拉框案例,我们可以看到其构成是“主关键词”+后缀副词:比如“企业排名优化”是主词,“巧推网”就是后缀词,我们在刷词的时候,后缀一般都是我们的品牌词.这样用户点击这个下拉词的时候,就会匹配到我们官网信息,从而起到引流的作用. 不仅如此,即时用户没有点击进来,也起到了增加我们品牌词曝光率. 刷下拉词的大概原理就是系统模仿用户的搜索
