android运行多个runnable

Question

我想一个接一个地运行两个可运行线程。

这意味着当第一个可运行线程完成时，第二个线程开始。

DownSpeedTester speedTester = new DownSpeedTester();
speedTester.setDownUrl(String.valueOf(urlDownload));
new Thread(speedTester).start();

UploadSpeedTester uploadSpeedTester = new UploadSpeedTester();
uploadSpeedTester.setUploadUrl(String.valueOf(urlUpload));
new Thread(uploadSpeedTester).start();

尝试使用 newSingleThreadExecutor 但没有成功。

ExecutorService es = Executors.newSingleThreadExecutor();
    Future< Boolean> result = es.submit(new Callable<Boolean>() {
        public Boolean call() throws Exception {
            //Download
            DownSpeedTester speedTester = new DownSpeedTester();
            speedTester.setDownUrl(String.valueOf(urlDownload));
            new Thread(speedTester).start();
            return true;
        }
    });
    try {
        boolean res = result.get();
        if (res == true){
            //Upload
            Log.d("mceeli","UploadSpeedTester");
            UploadSpeedTester uploadSpeedTester = new UploadSpeedTester();
            uploadSpeedTester.setUploadUrl(String.valueOf(urlUpload));
            new Thread(uploadSpeedTester).start();
        }
    } catch (Exception e) {

    }
    es.shutdown();

它仍然一起运行。

请帮助我。

使用单线程执行器，不再生成任何Thread:

ExecutorService es = Executors.newSingleThreadExecutor();
DownSpeedTester speedTester = new DownSpeedTester();
speedTester.setDownUrl(String.valueOf(urlDownload));
es.submit(speedTester);

UploadSpeedTester uploadSpeedTester = new UploadSpeedTester();
uploadSpeedTester.setUploadUrl(String.valueOf(urlUpload));
es.submit(uploadSpeedTester);

es.shutdown();
