  “白龙马蹄朝西，驮着唐三藏跟着仨徒弟…”，这首歌肯定可多人都听过，毕竟之前这首歌被一个小男孩唱火过一段时间。前一段时间学了css3的动画，那么我就跟风做一个唐僧四徒取经那回事吧！！！（ 其实是学了css之后，学姐给我发的实例，然后我就模仿着做了一个 ） 西游记   这个页面主要用到了css3的动画制作，background-position的使用与steps属性，好了废话不多说，先来看一下效果吧   有兴趣的话可以试一下，具体代码如下： <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>西游记</title> <style> body { width : 100% ; height : 100% ; margin : 0 ; padding : 270px 0 ; background-image : url(img/01.webp) ; background-repeat : repeat-x ; //水平铺展开 position : relative ; animation : bg 10000s linear infinite ; //动画bg隔10000s执行一次， //并且是无限循环下去 } @keyframes bg { from { background-position : -999999px

Android：ViewPager适配器PagerAdapter的使用

由 时间秒杀一切 提交于 2019-12-22 14:20:36
本文转载自： https://www.cnblogs.com/tinyphp/p/3891850.html 作者：tinyphp 转载请注明该声明。 PageAdapter是一个抽象类，直接继承于Object，导入包android.support.v4.view. PagerAdapter 即可使用。 要使用PagerAdapter， 首先要继承PagerAdapter类，至少覆盖以下方法： 在每次创建ViewPager或滑动过程中，以下四个方法都会被调用，而instantiateItem和destroyItem中的方法要自己去实现。 public abstract int getCount(); 这个方法，是获取当前窗体界面数 public abstract boolean isViewFromObject(android.view.View arg0, java.lang.Object arg1); 这个方法用于判断是否由对象生成界面 public java.lang.Object instantiateItem(android.view.View container, int position); 这个方法，return一个对象，这个对象表明了PagerAdapter适配器选择哪个对象放在当前的ViewPager中 public void destroyItem

SSRS: Report label position dynamic

由 陌路散爱 提交于 2019-12-22 12:21:44
问题 I have a report which displays customer address in multiple labels. My customers use windowed envelopes for mailing. I need the address labels position to be configurable. Something like, I'll have a database table which stores the Top/Left position of each label per customer. Based on this table, I need to position the address labels on my report. I thought, it is doable by expressions, but Location property doesn't provides ability to set an expression and make the label's top and left

主从复制配置 1、修改文件主库和从库文件 vi /etc/my.cnf [mysqld]下加入下面两行，log-bin自己取名，server-id局域网唯一，从库与主库区分(如果只是单向主从，则从库只设置server-id即可，双向主从则需要全部配置) log-bin=mysql-bin server-id=1 2、主库操作 创建从库访问的账户，%为接受所有请求，也可以限定IP地址访问，后面密码自己定义 CREATE USER 'slave'@'%' IDENTIFIED WITH mysql_native_password BY 'password'; 赋予账号复制的权限 GRANT REPLICATION SLAVE ON *.* TO 'slave'@'%'; 刷新权限 flush privileges; 查看主节点的二进制log和位置(Position) SHOW MASTER STATUS; 3、从库操作 CHANGE MASTER TO MASTER_HOST='主库地址', MASTER_USER='slave', MASTER_PASSWORD='password', MASTER_LOG_FILE='binlog.000006', MASTER_LOG_POS=Position; 后面两项为SHOW MASTER STATUS查询出的log名称和position

Android: programmatically get position of the widget on desktop relative to other widgets

由 会有一股神秘感。 提交于 2019-12-22 09:57:56
问题 On Android the user can place a widget on the desktop and then to move it by long touch and moving the finger while still holding. Is it possible to programmatically get the position on the screen where the widget was moved by long touch? I need my desktop widget to know if it's near the edge of the screen of the device. Depending on whether it's on the top of the desktop or at the bottom different layouts for the widget will be chosen. I would expect that this position is not given in pixels

C++ Class Memory Model And Alignment

由 半世苍凉 提交于 2019-12-22 08:52:42
问题 I have several questions to ask that pertains to data position and alignment in C++. Do classes have the same memory placement and memory alignment format as structs? More specifically, is data loaded into memory based on the order in which it's declared? Do functions affect memory alignment and data position or are they allocated to another location? Generally speaking, I keep all of my memory alignment and position dependent stuff like file headers and algorithmic data within a struct. I'm

Elasticsearch: match every position only once

由 佐手、 提交于 2019-12-22 06:34:15
问题 In my Elasticsearch index I have documents that have multiple tokens at the same position. I want to get a document back when I match at least one token at every position. The order of the tokens is not important. How can I accomplish that? I use Elasticsearch 0.90.5. Example: I index a document like this. { "field":"red car" } I use a synonym token filter that adds synonyms at the same positions as the original token. So now in the field, there are 2 positions: Position 1: "red" Position 2:

finding the last occurrence of an item in a list python

由 笑着哭i 提交于 2019-12-22 05:28:05
问题 I wish to find the last occurrence of an item 'x' in sequence 's', or to return None if there is none and the position of the first item is equal to 0 This is what I currently have: def PositionLast (x,s): count = len(s)+1 for i in s: count -= 1 if i == x: return count for i in s: if i != x: return None When I try: >>>PositionLast (5, [2,5,2,3,5]) >>> 4 This is the correct answer. However when I change 'x' to 2 instead of 5 I get this: >>>PositionLast(2, [2,5,2,3,5]) >>> 5 The answer here
