引入ExecutorService 类
private static final ExecutorService executes=Executors.newCachedThreadPool();
把需要处理的逻辑代码在放 run里面
需要传入参数 定义变量为final 类型
//定义变量为 final
final long size = imageFile.getSize(); Runnable runnable = new Runnable() {
public void run() {
//处理代码 }
};
executes.execute(runnable);
使用线程池 基类
/**
* 线程池类
* @ClassName ThreadPools.java
* @Description
* @author caijy
* @date 2015年6月9日 上午10:50:38
* @version 1.0.0
*/
public class ThreadPools {
private ThreadPoolExecutor threadPool;//线程池
private ThreadPools(){
//初始200 最大400
threadPool = new ThreadPoolExecutor(200, 400, 1,
TimeUnit.MICROSECONDS, new LinkedBlockingQueue<Runnable>()); }
private static ThreadPools instance = new ThreadPools();
/**
* 获取线程池的单例对象
* @return
*/
public static ThreadPools getInstance()
{
return instance;
}
/**
* 得到线程池
* @return
*/
public ThreadPoolExecutor getPools(){
return threadPool;
}
/**
* 提交线程
* @param <V>
* @param callable
* @return
* @throws InterruptedException
* @throws ExecutionException
*/
public <V> Future<V> submit(Callable<V> callable) throws InterruptedException, ExecutionException{
return threadPool.submit(callable);
}
/**
* 执行线程
* @param command
*/
public void execute(Runnable command){
threadPool.execute(command);
}
/**
* 关闭线程池
* @throws Exception
*/
public void shutDown() throws Exception{
threadPool.shutdown();
}
使用方式
//获取线程池
ThreadPools instance=ThreadPools.getInstance();
//拼接文件路劲
final String thumbnailFilePathName = realPath + File.separator + thumbnailPathName;
//拼接文件路劲
final String filePathNameTon = realPath + File.separator + pathName;
final long size = imageFile.getSize();
//保存图片成功后在 来压缩图片
Runnable runnable = new Runnable() {
public void run() {
//处理逻辑 }
};
instance.execute(runnable);
