问题 I have an adapter and a spinner view which is set to use the adapter for it's entries. I'm adding items to adapter from a list of all files in /assets/ folder, I found that this task takes very long time (even about 2 seconds for a list of 2 files on a 1.5Ghz phone!). Then I came up to use a worker thread to gather my list and not block UI thread. here is my code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.settings);

问题 In my Java application I have a Runnable such as: this.runner = new Runnable({ @Override public void run() { // do something that takes roughly 5 seconds. } }); I need to run this roughly every 30 seconds (although this can vary) in a separate thread. The nature of the code is such that I can run it and forget about it (whether it succeeds or fails). I do this as follows as a single line of code in my application: (new Thread(this.runner)).start() Now, this works fine. However, I'm wondering

问题 I know that shutdown() and awaitTermination() exist. The problem is that the runnables in the pool need to be able to add an unknown number (can't use a countdownlatch) of other runnables to it and if I call shutdown() those tasks will be rejected. How can I know when they're done? 回答1: Instead of submitting Runnable tasks to an Executor , you should rather use ForkJoinTask/ForkJoinPool instead. A ForkJoinTask runs inside a ForkJoinPool and can spawn an arbitrary number of (sub)tasks and wait

问题 I have multiple runnable classes and I want to run them with executor service through a centralized class (call it Launcher class which contains list of all runnables). I wrote a Launcher class which takes all the beans to instantiate using applicationContext.getBean() . Each runnable class also defines a pool size for it (number of threads to spawn for this runnable). public class DaemonsLauncher { @Autowired private ApplicationContext appContext; private List<Daemon> daemons = new ArrayList
