Relativelayout did not rewrite the following code as LinearLayout when implementing the Onmeasure method: @Override protectedvoid onmeasure (intint Heightmeasurespec) { if (morientation = = VERTICAL) { measurevertical (widthmeasurespec , heightmeasurespec); Else { measurehorizontal (Widthmeasurespec, Heightmeasurespec); } }Therefore, the system measurement layout cannot be notified after view.inflate if the root layout is relativelayout.Relativ

BarTender2016 Ruler unit of measure set method one: By default, the unit of measure for bartender 2016 is matched according to the system. If you use the Chinese version of the operating system, its default unit of measure is millimeters. You can modify the bartender label unit of measure in two

The loop complexity of the code (cyclomatic complexity, where it translates into cyclomatic complexity) is a measure of code complexity, presented by Thomas J. McCabe, Sr., in 1976.In the concept of software testing, cyclomatic complexity is used to measure the complexity of a module to determine the structure, the number of which is represented by the number of independent linear path, that is, reasonable

 The following is a brief list of common recommended system metrics: 1. Accuracy rate and Recall rate (Precision Recall) Accuracy and recall rates are two measures widely used in the field of information retrieval and statistical classification to evaluate the quality of the results. The accuracy is to retrieve the number of related documents and the total number of documents retrieved, to measure the precision of the retrieval system; Recall is t

Copy from https://blog.codecentric.de/en/2011/10/measure-java-performance-sampling-or-instrumentation/In recent discussions, I noticed a confusion on the differences between measuring with sampling andinstrum Entation.I hear about which one should was better than others, but I think it was important to understand what they work. Some Tools even ask to choose between those both directly at startup, like Jprofiler 7 in the picture on the right.But how c

Engineers who want to see these stories don't take a shot at their heads and think they've done the same thing. I have been in the field of testing and surveying for more than 10 years and have experienced many interesting stories. Of course, the characters in these stories are my placement, if there is a similar, purely coincidental. One man, at a cheap price, bought an adjustable linear power supply to power the part under test. The nominal noise value on this power supply specification is ver

Without human intervention, until one hours la

Preface In WPF/Silverlight, if an existing Element cannot meet your special needs and you may want to customize the Element, you may be faced with rewriting the MeasureOverride and ArrangeOverride methods, the two methods are provided by the Layout System of WPF/SL for user-defined interfaces. Therefore, it is necessary to understand the working mechanism of the Layout system and customize the Element. So how does the WPF/SL Layout system work? Next, let me briefly describe it and then analyze i

　　 to change the ruler unit of measure, follow these steps: Step one: Click on the "File" button. Step two: Click "Options" in the menu list on the left. Step three: On the left side of the Word Options dialog box that pops up, click the "Advanced" tab. Step four: Scroll down to the show section. Select an option from the unit of Measure Drop-down list. S

Java Database Connectivity (JDBC) is widely used in Java applications. In this article, we will discuss how to measure the performance of JDBC, and how to determine which part of the JDBC subsystem needs to be optimized. The core java.sql interface Our goal is to improve the performance of the application. In general, we need to analyze the application to find the bottleneck. Of course, it is difficult to analyze a distributed application effectivel

After updating the graphics driver, we are often prompted to update the "Windows Experience Index", but there is a possibility that when you detect Windows Media decoding performance, "Can not measure video playback performance," One of the reasons for this problem is that the paging file settings are too small, Or is the page file into the virtual disk RAMDisk virtual, small pieces to tell you how to solve. Case 1: Since the change of a graphics ca

How does Word change the default unit of measure? 1, as shown above, sometimes word's default units do not understand themselves, not accustomed to use. You can change it using the following method. Click the "Menu" button in the upper left corner. 2. Click on "Word Options" in the lower right corner of the menu. 3, in the Word Options window can see a lot of settings category, click "Advanced." 4, pull down th

WIN10 's new alarm clock application includes alarm clock, stopwatch, timer, world time four time settings related to the small software, we introduced the alarm clock and the use of stopwatch. So how do you use timers? Turn on the countdown. 　　How to Set We can use the mouse to move the end of the circle button to set our time. Set up, we can directly click on the middle of the "Start" button, so we can use the countdown function. Of course, if we need to, we can set up a "St

Σ algebraSo that X is a subset of the set of all subsets (subsets) of a sample space, the set X is called the Σ Algebra (Σ-algebra) and is called the σ domain (Σ-field).It has the following properties: (1) φ∈x; (Φ is an empty set)(2) If a∈x, then A's complement set a^c∈x;(3) If ai∈x (i=1,2,... ) is ∪ai∈x; Measurable spaceΩ is an arbitrary set, and X is a set of a subset of Ω that is stripped of the extremes in Ω, so that the rest is a set that can be processed, so (ω,x) is called t

View's measure mechanism and Viewmeasure Mechanism In Android, the View framework has three main processes: 1. measurement mechanism of the View tree Android View framework2. layout of the View tree Android View framework3. draw Mechanism of the Android View framework for drawing the View tree The workflow of the View framework is to measure the size of each View (measu
