biggest advantage of Android view is to get rid of some files and folders that we don't care about. (Configuration, properties files, etc.) and some resource files, the source files are very clearly merged together. Hiding some of the files and folders that are actively generated by themselves (such as r files, etc.) can allow us to manage the whole project/module more methods.Recommended articles Gradle Introduction http://stormzhang.com/devtools/2014/12/18/android-studio-tutorial4/

Attribute route and the traditional route map for a simple reason. The order of the route registration must be from the most precise matching rule to the normal matching rule, and finally the fuzzy matching rule, which avoids the early matching of the fuzzy rule in the route matching, and the relative exact match does not have any effect. This is shown in the following example:public static void RegisterRoutes (RouteCollection routes) { routes. Ignoreroute ("{resource}.axd/{*pathinfo}");

If you implement multiple methods, the logic of these methods is basically the same, the only difference is the number of parameters passed, you can use the variable parameterVariable parameter definition method data type ... The name of the array, which stores the arguments passed over, similar to JavaScriptNote the point:(1) Variable parameters need to be written in the parameter list of the method and cannot be defined separately(2) There can be only one variable parameter in the parameter li

数是数组索引结束位置，(不包含) index>=1index6. Splice () Method: The Array.splice () method is a generic method for inserting or deleting in an array. It modifies the called Array, splice () can pass in three parameters, the first parameter indicates where the index of the deleted element begins, the second parameter represents the total number of deleted elements, the third parameter represents the inserted element, and the position where the element was inserted is where the element was deleted.

why do absolute units and relative units appear?I think PT is a very useful unit, especially when it comes to printing. Now some of the page has been implemented display is a page, printing in another way, I want to print on the PT bar, because for different resolutions, the printed page is the same size. This is the first characteristic of an absolute unit. But keep in mind that, on display, this unit represents not the actual physical length, it is also adjusted according to the real size of
