Nowadays, the electronic distribution frame is no longer a new concept, and the use of intelligent management of the wiring system is the trend of the times. Almost all wiring manufacturers have launched their own electronic wiring rack solutions, which are dazzling. This article aims to make the simplest division and comparison of many electronic distribution frame systems, so that the decision makers can

Android event distribution mechanism To understand the Android event distribution mechanism, you must first understand several concepts and summarize them. If you cannot understand them for the moment, this article will explain these issues. 1. Click the screen. First, the event is transmitted from the dispatchTouchEvent () method of the Activity. 2. There are three methods for Android event

Touch event Distribution There are only two protagonists in Touch event distribution: ViewGroup and View. The Touch event of an Activity is actually a Touch event that calls its internal ViewGroup and can be processed as a ViewGroup directly. In ViewGroup, ViewGroup can also be in other viewgroups. In this case, the internal ViewGroup is used as View for analysis. There are three events related to ViewGroup

4G indoor distribution construction solution How to Implement indoor coverage has become the biggest challenge facing operators in the 4G era. Compared with 3G networks, the 4G indoor distribution system pays more attention to refined indoor coverage. system indicators should not only focus on field coverage, but also on capacity, signal quality, switching, frequency, and interference, and network construc

Android Touch gesture distribution and androidtouch gesture In the Touch distribution in android, we often see ACTION_DOWN-> ACTION_MOVE-> ACTION_UP. When we don't know how it is distributed, we always feel confused, therefore, it is necessary to understand its overall distribution process, so it is necessary to keep a good record. Event

Android event Distribution Methods related to Touch events in Android include dispatchTouchEvent (MotionEvent ev), onInterceptTouchEvent (MotionEvent ev), and onTouchEvent (MotionEvent ev) From this table, we can see that ViewGroup and its subclass can respond to the three methods related to Touch events, while Activity does not respond to onInterceptTouchEvent (MotionEvent ev), that is, event interception. In addition, you must note that the View res

IntroducedPrevious blog responsibility chain/Responsibility chain model (Chain of Responsibility) analytical understanding and application in AndroidThis paper introduces the responsibility chain model as the basis of understanding the view event distribution mechanism.To apply the structural analysis of the responsibility chain pattern, when our fingers are clicked or slid on the screen, it is an event, each view or viewgroup that is displayed on the

A random number generation algorithm for normal distributionAll of the above is a distributed random number generation algorithm, in scientific and engineering applications, the random number of normal distribution is often used. For a given normal distribution, the parameters describing the normal distribution include mean μ and variance, mathematically, an appr

The subject requirements are as follows: Given an array of input[], If the array length n is odd, the largest element in the array is placed in the middle of the output[] array, If the array length n is an even number, the largest element in the array is placed at the right position in the middle of the output[] array two positions, Then, in order from large to small, sequentially in the first position on both sides, according to the order of the left and right, in turn, the remaining number

In MongoDB (version 3.2.9), the distribution of data refers to splitting the collection data into chunks (chunk) and distributing them on different shards (shard). There are 2 main ways to distribute data: Balanced distribution based on the number of blocks (chunk) and directed distribution based on the Slice key range (range). The MongoDB built-in equalizer (bal

We have introduced the installation and simple configuration of hadoop in Linux, mainly in standalone mode. The so-called standalone Mode means that no daemon process is required ), all programs are executed on a single JVM. Because it is easier to test and debug mapreduce programs in standalone mode, this mode is suitable for use in the development phase. Here we mainly record the process of configuring the hadoop pseudo distribution mode. The so-cal
