Android开发中Thread线程的简单使用

Android开发中线程的简单使用

工具类

public class ThreadUtil {
    private BlockingQueue<Runnable> taskQueue = new LinkedBlockingQueue<Runnable>();
    private ExecutorService executorService = null;
    private volatile static ThreadUtil instance;

    public static ThreadUtil getInstance() {
        if (instance == null) {
            synchronized(ThreadUtil.class) {
                if(instance == null) {
                    instance = new ThreadUtil();
                }
            }
        }
        return instance;
    }

    public static void destroy() {
        if(instance != null) {
            instance.executorService.shutdownNow();
            instance.executorService = null;
            instance = null;
        }
    }

    private  ThreadUtil() {
        int NUMBER_OF_CORES = Runtime.getRuntime().availableProcessors();
        int KEEP_ALIVE_TIME = 1;
        TimeUnit KEEP_ALIVE_TIME_UNIT = TimeUnit.SECONDS;

        executorService = new ThreadPoolExecutor(NUMBER_OF_CORES,
                NUMBER_OF_CORES*2,
                KEEP_ALIVE_TIME,
                KEEP_ALIVE_TIME_UNIT,
                taskQueue ,
                new ThreadPoolExecutor.AbortPolicy());
    }

    public void execute(Runnable command) {
        if(executorService != null) {
            executorService.execute(command);
        }
    }

}

用法

ThreadUtil.getInstance().execute(new Runnable() {
				@Override
				public void run() {
					
				}
			});
