Retrieve the X & Y coordinates of a button in android?

由 ∥☆過路亽．° 提交于 2019-12-18 04:48:12
问题 I've been working on Android for a while and would like to know if it is possible to retrieve the position of a button in android. My target is to get the X & Y coordinates and print them on the LOGCAT. Some example to show me how would be appreciated. Thanks 回答1: Sure, you can get these, make sure the views are drawn atleast once before you try to get the positions. You could try to get the positions in onResume() and try these functions view.getLocationInWindow() or view.getLocationOnScreen

约瑟夫问题(单向循环对列)

题目描述： 题目解析： 该题是是基于单向循环队列实现的，其实简单点来说就是隔两个结点删一个结点，直至剩下两个结点，然后把两个结点中存储的数据输出。 解题步骤： 1.定义结点内部类，用于描述结点 2.创建关于创建链表的构造函数，通过for循环把结点位置一确定，每个结点的数据域中存储该结点的位置 3.编写函数删除指定位置的元素，将最终剩余的两个节点的位置一同放入一个线性表中，返回该线性表。如下图所示删除： 完整代码： package Ds02 . 动态链表 ; import DS01 . 动态数组 . ArrayList ; import DS01 . 动态数组 . List ; //约瑟夫环 真实头结点 循环一类的都是基于循环链表 public class JosephusLoop { private Node head ; private Node rear ; private int size ; public JosephusLoop ( int count ) { head = new Node ( 1 , null ) ; rear = head ; rear . next = head ; for ( int i = 0 ; i <= count ; i ++ ) { rear . next = new Node ( i , rear . next ) ; //尾插法

Adding an automatic offset to the scroll position for all hash-links/calls

由 元气小坏坏 提交于 2019-12-18 03:56:10
问题 I have the following problem: Like on Facebook, I have a menu bar at the top of the page that is always visible ( position: fixed; ). When I now click hash-links on my page (or load a new page with a hash in the url) to jump to a certain element on the page, the browser always scrolls this element to the very top of the page, meaning that the element is behind the top menu bar, afterwards. I'd like to add some Javascript (jQuery or normal Javascript) that automatically adds a (negative)

问题 Hello i would like to know the on-screen position of some element. I know how to get the position of element in python selenium webriver but how to get offset from left-top corner of screen? 回答1: I guess it's not possible to define distance from top-left corner of browser window to top-level corner of screen with just selenium . But you can try to implement following: driver = webdriver.Chrome() driver.maximize_window() # now screen top-left corner == browser top-left corner driver.get("http:

Css Sibling Absolute Positioning

由 本小妞迷上赌 提交于 2019-12-18 03:01:34
问题 Is there any way to absolutely position a div relatively to its sibling? For example: Inside a div there are two other divs - div1 and div2. I want to absolutely position div2 relatively to div1. 回答1: Absolute positioning is dependent on the "current positioning context", which may include a parent element (if absolutely or relatively positioned) but will never include a sibling element. Can you reorganize your dom so that you have a parent-child instead of siblings? If so, you could set the

问题 does anyone know the best way to insert a column in a datatable at position 0? 回答1: You can use the following code to add column to Datatable at postion 0: DataColumn Col = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean")); Col.SetOrdinal(0);// to put the column in position 0; 回答2: Just to improve Wael's answer and put it on a single line: dt.Columns.Add("Better", typeof(Boolean)).SetOrdinal(0); UPDATE: Note that this works when you don't need to do anything else

Get element position after transform

由 醉酒当歌 提交于 2019-12-18 02:54:12
问题 I have a UIElement that has various transformations performed on it (scale and translate). Is there a way to get the UIElement's position after transformation? I tried GetValue(Canvas.TopProperty) but it doesn't change from what it was loaded as. I must be missing something obvious but not sure what. (I'm using silverlight) 回答1: It is a little bit unintuitive to do this, but it can be done. It is a two step process. First, what you want to use the TransformToVisual function (from MSDN):

position之fixed固定定位、absolute绝对定位和relative相对定位

什么是层模型？ 什么是层布局模型？层布局模型就像是图像软件PhotoShop中非常流行的图层编辑功能一样，每个图层能够精确定位操作，但在网页设计领域，由于网页大小的活动性，层布局没能受到热捧。但是在网页上局部使用层布局还是有其方便之处的。下面我们来学习一下html中的层布局。 如何让html元素在网页中精确定位，就像图像软件PhotoShop中的图层一样可以对每个图层能够精确定位操作。CSS定义了一组定位（positioning）属性来支持层布局模型。 层模型有三种形式： 1、 绝对定位 (position: absolute) 2、 相对定位 (position: relative) 3、 固定定位 (position: fixed) 层模型--绝对定位 如果想为元素设置层模型中的绝对定位，需要设置 position:absolute (表示绝对定位)，这条语句的作用将元素从文档流中拖出来，然后使用left、right、top、bottom属性相对于其最接近的一个具有定位属性的父包含块进行绝对定位。如果不存在这样的包含块，则相对于body元素，即相对于 浏览器窗口 。 如下面代码可以实现div元素相对于浏览器窗口向右移动100px，向下移动50px。 div{ width:200px; height:200px; border:2px red solid; position
