Android Service两种启动方式详解(总结版)

1. 概念 开始,先稍稍讲一点android中Service的概念和用途吧~ Service分为本地服务(LocalService)和远程服务(RemoteService): 1、本地服务依附在主进程上而不是独立的进程,这样在一定程度上节约了资源,另外Local服务因为是在同一进程因此不需要IPC, 也不需要AIDL。相应bindService会方便很多。 主进程被Kill后,服务便会终止。 2、远程服务为独立的进程,对应进程名格式为所在包名加上你指定的android:process字符串。由于是独立的进程,因此在Activity所在进程被Kill的时候,该服务依然在运行, 不受其他进程影响,有利于为多个进程提供服务具有较高的灵活性。该服务是独立的进程,会占用一定资源,并且使用AIDL进行IPC稍微麻烦一点。 按使用方式可以分为以下三种: 1、 sta r tSe r vice 启动的服务: 主要用于启动一个服务执行后台任务, 不进行通信 。停止服务使用stopSe r vice; 2、 bindSe r vice 启动的服务: 该方法启动的服务可以 进行通信 。停止服务使用unbindSe r vice; 3、startService 同时也 bindService 启动的服务:停止服务应同时使用stepService与unbindService 2.

问题 If you go to an article on The Economist website. For example: http://www.economist.com/node/17629757 When you scroll down the page past a certain point (either with the PAGEDOWN button or by incrementally scrolling with the DOWNARROW key), a red sticky header appears. Is that jQuery? How is that implemented? 回答1: The content, while added via JavaScript is just position: fixed. 回答2: The Economist uses Apture, a service which includes the sticky header and a few other features on the page.

How to make the jQuery Sticky Float plug-in react live to page changes?

半腔热情 提交于 2019-12-06 13:30:31
I've been looking at the really rather wonderful 'stickyfloat' plug-in ( http://plugins.jquery.com/files/stickyfloat_0.htm ) for jQuery for a project I'm working on. I need to keep a panel on the right of the page 'in view' as the content on the left scrolls. The stickyfloat plug-in works a treat but it doesn't update it calculations if you use jQuery to effect the length of the content block in which it sits. Is there any way I might be able to adjust this plug-in to make it respect live changes to the content div height? I wrote this plugin, and I have re-posted it and fixed this issue of

Android ListView: Change from Scrolling Header to Sticky

梦想的初衷 提交于 2019-12-06 11:40:37
问题 How can I make a header inside a listview that scrolls normally but when you scroll down too much so that it would vanish at the top it becomes fixed/sticky at the top. I have added the header with addHeaderView but I suppose this isn't possible if you want to implement what I described. How can it be done? 回答1: There is a 3rd party library that can do exactly what you want right here https://github.com/emilsjolander/StickyListHeaders the ability to do this is not in the SDK 来源: https:/

Make position: fixed behavior like sticky (for Vue2)

大憨熊 提交于 2019-12-06 02:14:11
Position: sticky doesn't support by the most mobile browsers. But position: fixed is not that thing I need (because of fixed block overlaps content in the bottom of document). I guess for jquery it will be easy to set static position for fixed block if we get bottom of document onscroll. But for Vue2 I haven't any idea how to do the same. Give some advice please. Or maybe better solution exists. As I mentioned in the comments, I'd recommend using a polyfill if at all possible. They will have put a lot of effort into getting it right. However, here is a simple take on how you might do it in Vue

底部粘连(stiky footer)布局

天涯浪子 提交于 2019-12-05 16:39:12
本文转载于: 猿2048 网站 底部粘连(stiky footer)布局 前面的话   在网页设计中,Sticky footers设计是最古老和最常见的效果之一,大多数人都曾经经历过。它可以概括如下:如果页面内容不够长的时候,页脚块粘贴在视窗底部;如果内容足够长时,页脚块会被内容向下推送。本文将详细介绍sticky footer的4种实现方式 绝对定位   常见的实现方法是对(.sticky)footer进行绝对定位,假设高度为50px。对父级(.box)进行相对定位,将html、body的高度设置为100%,父级(.box)的最小高度设置为100%,将(.content)内容部分设置padding-bottom为footer的高度,即50px,这里不用margin-bottom是因为会出现margin-bottom传递的情况   [注意]关于margin传递的详细情况 移步至此 <style> html,body{height: 100 % } body{margin: 0 } .box{position:relative;background -color:lightblue;min-height: 100 % ;} .content{padding - bottom:50px;} .sticky{position:absolute;background -color
