Resizing the View Controller’s Views A view controller owns its own view and manages the view’s contents. In the process, the view controller also manages the view’s subviews. But in most cases, the view’s frame is not set directly by the view contro…

 Android点击View显示PopupWindow,再次重复点击View关闭PopupWindow 这本身是一个看似很简单的问题,但是如果设置不当,就可能导致莫名其妙失效问题.通常在Android中使用PopupWindow是从某一个View中触发,为某一个View setOnClickListener,然后在View.OnClickListener中show出创建好的PopupWindow,比如下图右侧的"筛选"部位View,此图为用户点击 筛选 后弹出的PopupWindo…

前言 自己定义View是Android开发人员必须了解的基础 网上有大量关于自己定义View原理的文章.但存在一些问题:内容不全.思路不清晰.无源代码分析.简单问题复杂化等等 今天,我将全面总结自己定义View原理中的layout过程,我能保证这是市面上的最全面.最清晰.最易懂的 文章较长.建议收藏等充足时间再进行阅读 文件夹 imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="文件夹" title="&…

将题意转换为一开始\(t = 0\),第\(i\)个操作是令\(t \leftarrow (a_i + 1) t + (a_i + b_i + 1)\).记\(A_i = a_i + 1, B_i = a_i + b_i + 1\).问经过最多经过多少次操作后才能使得进行完这些操作后\(t \leq T\)仍然满足. 我们先推一个贪心性质: 若先进行\(i\)操作,再进行\(j\)操作时满足条件,且\(\frac{A_i - 1}{B_i} < \frac{A_j - 1}{B_j}\),则可以…

首先,我们将题目理解成若\(i\)与\(j\)距离恰好为\(3\),则不可能\(p_i \equiv p_j \equiv 1 \space or \space 2 (\bmod 3)\).这就相当于我们要构造一个大小为\([\frac{n + 1}{3}]\)的点集\(A_2\),用来放所有模3余2的数,再构造一个大小为\([\frac{n + 2}{3}]\)的点集\(A_1\),用来放所有模3余1的数.需要满足这两个集合交集为空,且若\(i\)与\(j\)距离为\(3\),则它们不在同一个…

salesforce给我们提供了标准的页面,比如标准的页面包括标准的列表和标准的详细页视图.有的时候我们想要自定义视图,比如做一个项目的时候不希望使用者直接通过ID查看到标准的详细页,而是跳转到指定处理过的详细页,这个时候做法如下: 1.创建相关详细页的Controller,此Controller的构造函数应涵盖ApexPages.StandardController,ApexPages.StandardSetController两个参数 public without sharing class…

近段时间研究了下angular.js 觉得它内部实现的view和model层之间存在很微妙的关系,如下图 如上图说的,view的改变会update 数据层model, 数据层会update视图层view,这双方之所以能实现互相的监听,就是通过中间层(理解为监听层),代码初始化的时候就会将view和model的相关状态都保存在监听层里面(可以理解为保存一个handler的函数到监听层里面), view和model的改变都触发监听器里面的绑定的handler,实现状态的共享; 个人简单实现了下,可能…
