Measurement and rendering of Android view

This article is from the Android Elite biography (Xu Yisheng)I wrote here, I think Xu Yisheng is really good, but also added some of their own understanding, to facilitate their own foundation to improve.If you want to draw a view, you need to take a measurement first, that is, you need to know its size and location. So we can slide it out of the screen. This process is done in the Onmeasure () method.I. Measureme

Summary of image similarity measurement and template matching

SummaryThis paper mainly summarizes the image similarity measurement and template matching method used in target tracking and detection, and gives the specific code implementation based on OPENCV.IntroductionTemplate matching is a technique that looks for the most similar image patches in the source image, and is often used to identify, track and detect targets. The most similar must be based on some similarity criterion, that is, the need for similar

Performance optimization of 5.28 large-pressure measurement-related problems of thread pool

, check the single service, the settlement page is successfully measured through. But when the payment callback service was pressed, a strange problem arose.1. Introduction to the EnvironmentWe basically two times a year, 5.28, double 12. Two times during the big promotion period is only half a year or so, so every time the big pressure test will be a little low in the heart, the basic is the mapping under inspection. Because the previous test performance during this six months generally does no

(17) Principle and realization of measurement of distance and area in Webgis

1. BackgroundIn this chapter we will discuss two other common tools in the Basic toolbar: Distance measurement tool box Area measurement tool.The distance measurement tool requires the following functions:A. By clicking on a mouse, each point of click is connected to a line segment on the map.B. The actual distance represented by this segment at each segmentC. Do

Function-oriented software measurement

Function-oriented Measurement From: http://www.zxbc.cn/html/rjgc/2019251939768.html Function-oriented software measurements are indirect measurements of software and software development processes. Function-oriented measurements focus on the program's "functionality" and "Practicality", rather than counting loc. This metric was first proposed by Albrecht. He proposed a productivity measurement

"Function Point Analysis-measurement practices for successful software projects"

I read this book because I read 《Software Engineering Project Management: function analysis methods and practicesLeft a bunch of questions. I have borrowed it from the library for almost two weeks, but I just flipped it over. The degree of seriousness is far less than that of the previous book. It's not that this book is not good, but the structure is not easy for me to clarify the clues. I don't know how other people are doing. In my opinion, there is a lot of nonsense. A book with more than 40

Activity Measurement (Measure), layout, and drawing (draw) Process analysis

An Android application window contains a lot of UI elements, which are organized in a tree structure, where there is a parent-child relationship where the child UI element is inside the parent UI element, so before drawing the UI of an Android application window, We first determine the size and position of each child UI element within the parent UI element. The process of determining the size and position of individual child UI elements within a parent UI element is also known as the

Talking about the compression perception (15): The spark constant of the measurement matrix

In the sense of compression, there are some indicators used to evaluate the measurement matrix, such as common rip, and spark constants can be used to measure the suitability of a measurement matrix in addition to rip.1, 0 space conditions null spaces ConditionBefore introducing Spark, consider the 0 space of the measurement matrix.Here we consider the conditions
