because the DPI (PPI) is raised. (DPI or PPI is dots per inch or pixels, which represent density.) )
So, 320 this width (3XX) as the reference width, also known as one-size lineage down. Because using 1 as the base, the conversion is really convenient.
The following figure is the design output size and resolution comparison table.

For iOS, the same concept, unlike Android, the 320-wide reference resolution of the exported material is @1x, also known as one-times graph. Th

The example above shows that after calling, extend can inherit the methods and attributes of the base.
By the way, use apply in the prototype of the javascript framework to create a schema that defines classes,
The implementation code is as follows:
The Code is as follows:
Var Class = {Create: function (){Return function (){This. initialize. apply (this, arguments );}}}

We know that Motorola is working hard to enable its smartphones to quickly upgrade to Android 5.0 Lollipop. Now it looks like the upgrade time is earlier than expected. A few days ago Motorola leaked a beta version of Android 5.0 Lollipop that was only tested by Motorola smartphone Saker users. As a result, Motorola will be expected to upgrade its Android 5.0 lollipop for several smartphones within weeks via OTA. More about the latest information on Android System application development focus o

The Moto Droid assembles the components that are logically part of BP, as well as the devices belonging to the AP, on the same board. And the iphone 3GS, although the AP and BP devices are assembled on the same circuit board, but isolated in

A year ago, I am eager to record my job-seeking experience for reference.Actual record: ZeroCause 1: The network is too bad. The speed is definitely too bad outside the BUPT.Cause 2: when there is no offer, you are depressed and have no mood to write. When there is an offer, you are lucky and have no time to write.
Today, I received a letter from the younger brother (or younger sister) who has followed this blog. It's time to come back and check it out.

Introduction
Moto E2 is a cost-effective Linux smartphone, but it has not opened its local graphics library SDK for some commercial reasons, which greatly reduces its competitiveness and scalability. This article describes how to export the corresponding header file and write the corresponding program code without relevant information based on my experience in writing my applications.
Note: This article is not intended for general mobile phone users.
change the object context of a function from the initial context to the new object specified by thisarg.If the thisarg parameter is not provided, the global object is used as the thisarg

There is another technique in applying CALL and apply, that is, after applying CALL and apply to another function (class), the currentA function (class) has another function (class) method or attribute, which can also be called "inheritance ". See the following example:

Resolution: From the code, this object only contains one method: Create, which returns a function, that is, a class. But this is also a classThe constructor calls initialize, which is the initialization function defined during class creation. In this way,The class Creation Mode in prototype can be implemented.Example:Copy codeThe Code is as follows: var vehicle = Class. Create ();Vehicle.

Is the iPhone the first mobile phone of apple?
In fact, this question is a little "white". I would like to say a few more words to the small K who pays attention to the history of some enterprises. IPhone is Apple's mobile phone designed and manufactured by itself, but it is not Apple's first mobile phone.
So what is the first mobile phone related to Apple?
When you buy a mobile phone, are you entangled in several mobile phones? Do you still remember the times when I heard "hellomoto" in mantai

In this way, you can implement the class creation pattern in prototypeExample: var vehicle=class.create (); vehicle.prototype={initialize:function (type) {this.type=type; }, Showself:function () {alert ("This vehicle is" + this.type); }}var moto=new vehicle ("moto"); Moto.showself ();Operation Result: Thisvehicle is Moto Example 3:f

One of the methods that run through the time domain and frequency domain is the Fourier analysis in the text of the biography. Fourier analysis can be divided into Fourier series (Fourier Serie) and Fourier Transformation (Fourier transformation). Let's start with a simple introduction.2. Spectrum of Fourier Series

If I say that I can use the sine wave mentioned above to create a rectangular wave with a 90 degree angle, will you believe it? You won't, just like me.
IOS development-iPhone 6/6 Plus adaptation
It took some time to reorganize the iPhone adaptation, which is summarized as follows:
Before iOS6, autosize is generally used for screen adaptation, and the size relationship defect between the view and the parent view is set: (Autosizing layout is insufficient) 1. the relationship between views cannot be set. 2. you cannot set the maximum size for resizing. After the minimum value is iOS6, use the automatic layout. AutoLayoutiOS8 size classes (more a
