Merge multiple Sass maps

由 五迷三道 提交于 2020-01-11 04:04:17
问题 I have three Sass maps that I want to merge into one map. With the map-merge function I can only merge two maps together. How can I merge more than two maps? A shortened example of my situation: $color-name: ( blue: ( default: blue, dark: navy, light: sky ) ); $color-event: ( danger: ( default: set($color-name, red), dark: set($color-name, red, dark), light: set($color-name, red, light), ) ); $color-category: ( heading: ( default: set($color-name, grey), dark: set($color-name, grey, dark),

MapOverlay binding not working

由 不想你离开。 提交于 2020-01-11 03:33:08
问题 I'm trying to get a map overlay working on Windows Phone 8 using an MVVM code structure. I can't seem to get the GeoCoordinate property of the MapOverlay to bind to my ViewModel properly and I can't work out why. The XAML as stands is: Header: xmlns:maps="clr-namespace:Microsoft.Phone.Maps.Controls;assembly=Microsoft.Phone.Maps" Code: <maps:Map x:Name="Map" ZoomLevel="6" Height="500" Width="500" CartographicMode="Terrain" Center="{Binding MapCenter, Converter={StaticResource

Plotting a raster with the color ramp diverging around zero

由 我只是一个虾纸丫 提交于 2020-01-10 08:30:09
问题 I am trying to plot a map with positive and negative values. All positive values should have red color while negative should have blue color and zero should have white just like in this sample plot with discrete colors Below is the code I'm using: library (rasterVis) ras1 <- raster(nrow=10,ncol=10) set.seed(1) ras1[] <- rchisq(df=10,n=10*10) ras2=ras1*(-1)/2 s <- stack(ras1,ras2) levelplot(s,par.settings=RdBuTheme()) Thanks very much for providing a general solution which can be applied in

[leetcode 周赛 157] 1217 玩筹码

由 馋奶兔 提交于 2020-01-10 01:51:58
1217 Play With Chips 玩筹码 题目描述 数轴上放置了一些筹码，每个筹码的位置存在数组 chips 当中。 你可以对 任何筹码 执行下面两种操作之一（不限操作次数， 0 次也可以）： 将第 i 个筹码向左或者右移动 2 个单位，代价为 0 。 将第 i 个筹码向左或者右移动 1 个单位，代价为 1 。 最开始的时候，同一位置上也可能放着两个或者更多的筹码。 返回将所有筹码移动到同一位置（任意位置）上所需要的最小代价。 示例 1： 输入 ：chips = [1,2,3] 输出 ：1 解释 ：第二个筹码移动到位置三的代价是 1，第一个筹码移动到位置三的代价是 0，总代价为 1。 示例 2： 输入 ：chips = [2,2,2,3,3] 输出 ：2 解释 ：第四和第五个筹码移动到位置二的代价都是 1，所以最小总代价为 2。 提示： 1 <= chips.length <= 100 1 <= chips[i] <= 10^9 思路 读题 移动奇数次位置代价为1, 移动偶数次位置代价为0, 寻找一个位置, 距离其他位置的距离尽量都是偶数 思路一 遍历所有位置, 选取最小代价 使用HashMap<Integer, Integer>存储 位置 和 该位置上的元素个数 循环变量, 每个位置与其他位置的距离, 加上其他位置的元素个数, 从而计算出代价 选出最小代价输出

Android Maps V2 MapView inside custom fragment (NPE)

由 让人想犯罪 __ 提交于 2020-01-09 13:02:49
问题 I do not want to use or extend SupportMapFragment or MapFragment . I have my own base class with a bunch of code in it. The documentation clearly states that when someone uses MapView by itself, all corresponding lifecycle methods ( onCreate() onResume() etc.) should be called. Most of the lifecycle methods in a Fragment are similar to an Activity but when I switch back and forth between my Fragment I eventually get an obfuscated NPE in onDestroy() or in onResume() methods. All the samples

问题 I am making an android application that needs to search in my local area within 10km and display the results onto a map using pins, For example: "Starbucks", "Wallmart", Shopping mall, etc. The search word that i specify in my activity class. And to be clear: I do NOT want to open the search in Google maps, i want it to display the results inside MY own application. But i get an error at the code that executes the search. The error comes up on the following things: Url: url cannot be resolved
