问题 I set the test name in my test class using annotation: @Test(testName = "sth") and I need to get it from Listener class which implements ITestResult. Method getTestName() returns null but according to http://testng.org/javadocs/org/testng/ITestResult.html#getTestName-- should returns the string. Am I doing sth wrong? Is it possible to get the string set in @Test(testName = "") from Listener class? 回答1: getTestName() may return null in some case. Check no regression test from TestNG if you

问题 I need to implement a voice activity detection algorithm in Java so that I can know when to start and/or stop recording audio. I am looking for an algorithm that can take either a byte[], a target-data-line, or an audio file as input. Also, a solution would preferably not use external dependencies. 回答1: Give a look at TarsosDSP as source of inspiration: It is so far the best open source Java library to deal with Audio Detection. It is purely written in Java and briefly provides:

问题 When receiving requests on my servlet, i would like execute one listener class which is related with, and which contains some instructions. So i implement on myListener the interface ServletContextListener, like this: public class MyContextListener implements ServletContextListener { @Override public void contextDestroyed(ServletContextEvent arg0) { // TODO Auto-generated method stub } @Override public void contextInitialized(ServletContextEvent arg0) { System.out.println("Context Created");

问题 I am building an application that needs to refresh the UI every time view bounds changes. I tried the view.addOnLayoutChangeListener() but it called a lot of times. As wrote in the answer it happens because I didn't remove the LayoutChangeListener , But I want to keep it for the next events. So my question is: How can I listen for several LayoutChange events (not only for the first one)? code: int counter=0; view.addOnLayoutChangeListener(new View.OnLayoutChangeListener() { @Override public

问题 I want to write a function that constantly listens for changes in a redis list (usually when elements are pushed to the list) and pops its elements whenever the list is not empty. Then it will execute a function on the popped elements. How should I implement this? 回答1: You can use notify-keyspace-events for that example with Node.js but the idea is similar for other languages. const Redis = require('ioredis') const redis = new Redis() ;(async function () { redis.on('ready', () => { console

问题 Consider the following code: StreamBuilder<QuerySnapshot> _createDataStream(){ return StreamBuilder<QuerySnapshot>( stream: Firestore.instance.collection("data").limit.(_myLimit).snapshots(), builder: (context, snapshot){ return Text(_myLimit.toString); } ); } I want that the StreamBuilder refreshes when the _myLimit Variable changes. It's possible doing it like this: void _incrementLimit(){ setState(() =>_myLimit++); } My Question is if there is another, faster way, except the setState((){})
