runnable

问题 I have defined the following Spring boot application: @SpringBootApplication public class Application implements CommandLineRunner { public static void main(String[] args) { new SpringApplicationBuilder(Application.class).web(WebApplicationType.NONE).run(args); } public void run(String... args) throws Exception { Thread.currentThread().join(); } } I also have a package of workers (i.e. could be classes which implements Runnable ). They are supposed to run indefinitely. What is the "Spring way

问题 To update the GUI from other threads, there are basically two main approaches: Use java.lang.Runnable with any of these methods: Activity.runOnUiThread(Runnable) View.post(Runnable) View.postDelayed(Runnable, long) Handler.post(Runnable) Use android.os.Message: Handler.sendMessage(Message) / Handler.handleMessage(Message) You can also use AsyncTask, but my question is more focused on the use case of updating a very simple component. Let's see how it would be done using both approaches: Using

问题 I have been trying to optimize my single thread app which loads a bunch of tiles that makeup a large bitmap. The app was becoming very sluggish when it would load the new tiles into system memory. Im now looking trying to use Async Tasks for this purpose. The app detects which tile is in the top left in a method called by onDraw, creates a string that contains the path of the bitmap in the Assets folder, and then checks to see if the bitmap is null before drawing. If it is null, it will load

问题 I want to create multiple handler and run-able when my app receive response from server. The handlers can be maximum 4 and minimum 1. Problem Actually i want to divide cell screen in different part and after dividing i need to display different type of data in all parts of the screen. And in these parts, Each part have multiple items to display. e.g! User want to divide screen in two parts part one contains a video, image and again a video. (3) item in part one part two contain image and a

问题 - I am working on a project which needs to play video in slow motion. - I am well aware that Android doesn't provide these functionality. - I found PVPlayer Engine and libVLC which possessed these capabilities, but i didn't found any tutorial or proper documentation of including them in the android project and using them. - So i tried doing this by using Runnable and Handler , it was successful in slowing down the video but they possessed jerks during playing. public class MainActivity

问题 I've come to the conclusion after reading from many sources that using printStackTrace for error handling is bad practice. Here's one. Now I'm struck curious: in what cases is printing the stacktrace a valid solution? For the sake of the argument, let's assume we aren't working on a system such as a microwave or a banana, but a basic out-of-the-shelf PC. The reason I'm asking this could be seen as a question in itself, but I'll tell you about it anyhoo: I'm developing a snake-like game that
