在后台线程中运行处理程序的消息

我要运行一些可运行在后台线程。我想用处理程序，因为它的方便延迟。 我的意思是

I want to run some Runnable in a background thread. I want to use Handler because it's convenient for delays. What I mean is

handler.post(runnable, delay);

其中可运行应背景线程运行。 是否有可能创造这样的处理程序？ 是否有背景尺蠖的地方或者我如何创建呢？

Where runnable should be run in background Thread. Is it possible to create such Handler? Is there a "background" Looper somewhere or how can I create it?

P.S。我知道如何与自定义类做扩展线程，但它需要多一点的编码工作不是做它的处理方式。所以，请不要张贴其他的解决方案或类似的东西。

P.S. I know how to do it with a custom class extends Thread but it requires a little more coding effort than doing it the handler way. So please don't post other solutions or something like

handler.post(new Runnable() {
    @Override
    public void run() {
        new Thread() {
            @Override
            public void run() {
                //action
            }
        }.start();
    }
});

我只是游荡，如果处理程序能做到这一点干净的方式。

I just wander if Handler can do it the "clean" way.
