Android: custom separator (or even item) in ListView depening on content of item

由 谁说胖子不能爱 提交于 2019-11-27 03:24:29
I've a ListView with items containing information about places with a rating and the distance to the current location. The items are sorted into groups: Group 1: within 500m Group 2: 500m - 1km Group 3: 1km - 1.5km ... Withing these groups the items are sorted by their rating. Now I put out these items via my custom adapter (extension of BaseAdapter ) into the ListView , which works perfectly. However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any

C# decimal separator?

由 怎甘沉沦 提交于 2019-11-27 03:15:11
问题 I have a method which returns numbers like this: public decimal GetNumber() { return 250.00m; } Now when this value is printed to the console for example, it has a comma (250,00) instead of a point (250.00). I always want a point here, what am I doing wrong? 回答1: decimal itself doesn't have formatting - it has neither a comma nor a dot. It's when you convert it to a string that you'll get that. You can make sure you get a dot by specifying the invariant culture: using System; using System

What does print(… sep='', '\t' ) mean?

由 五迷三道 提交于 2019-11-27 01:23:03
问题 I am having a bit of trouble trying to find an answer to this. I would like to know what the syntax sep="" and \t means. I have found some informaion about it but I didn't quite understand what the purpose of using the syntax was. I'm looking for an explanation of what it does and when / why you would use it. An example of sep='' being used: print('Property tax: $', format(tax, ',.2f'), sep='') 回答1: sep='' in the context of a function call sets the named argument sep to an empty string. See

GROUP_CONCAT comma separator - MySQL

由 不羁岁月 提交于 2019-11-26 23:53:54
问题 I have a query where I am using GROUP_CONCAT and a custom separator as my results may contain commas: '----' This all works well, however it is still comma separated, so my output is: Result A----,Result B----,Result C---- How can I make it so the output is: Result A----Result B----Result C---- I thought this was the idea of a custom separator! Failing that, can you escape commas in your results, so I can explode in PHP by the GROUP_CONCAT commas? 回答1: Looks like you're missing the SEPARATOR

Adding Thousand Separator to Int in Swift

由 [亡魂溺海] 提交于 2019-11-26 22:20:26
I am fairly new to Swift and having a great deal of trouble finding a way to add a space as a thousand separator. What I am hoping to achieve is taking the result of a calculation and displaying it in a textfield so that the format is: 2 358 000 instead of 2358000 for example. I am not sure if I should be formatting the Int value and then converting it to a String, or adding the space after the Int value is converted to a String. Any help would be greatly appreciated. You can use NSNumberFormatter to specify a different grouping separator as follow: update: Xcode 9 • Swift 4 extension

HTML + CSS: Ordered List without the Period?

由 你离开我真会死。 提交于 2019-11-26 18:38:56
I think the answer to this question is no... but does anyone know of a an HTML/CSS way to create an ordered list without a period after the numbers? Or, alternatively, to specify the separator character? Ideally I don't want to do list-style-image with a different class for each number, but that's all I've been able to think of so far... That seems terribly unsemantic. IE: Default Style: 1. ______ 2. ______ 3. ______ Desired Style: 1 ______ 2 ______ 3 ______ Alternate Style: 1) ______ 2) ______ 3) ______ This is perfectly possible to do with just CSS (2.1): ol.custom { list-style-type: none;

Separators For Navigation

由 六眼飞鱼酱① 提交于 2019-11-26 17:26:10
问题 I need to add separators between elements of navigation. Separators are images. My HTML structure is like: ol>li>a>img . Here I come to two possible solutions: To add more li tags for separation (boo!), Include separator in image of each element (this is better, but it makes possibility that user may click on, example, "Home", but get to "Services", because they are one behind the other and user may accidentally click on separator that belongs to "Services"); What to do? 回答1: Simply use the

How to read records terminated by custom separator from file in python?

由 人盡茶涼 提交于 2019-11-26 16:55:39
问题 I would like a way to do for line in file in python, where the end of line is redefined to be any string that I want. Another way of saying that is I want to read records from file rather than lines; I want it to be equally fast and convenient to do as reading lines. This is the python equivalent to setting perl's $/ input record separator, or using Scanner in java. This doesn't necessarily have to use for line in file (in particular, the iterator may not be a file object). Just something
