我如何在 OnClick 方法中处理我的 Looper 以 运行 延迟函数?

How can i handle my Looper in an OnClick method to run a function with delay?

我希望能够 运行 通过单击事件中的循环程序在后台执行我的特定方法,这是正确的方法吗?

myThread = new LooperThread();
    myThread.start();
    upload.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
        }
    });
    stop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            myThread.handler.post(new Runnable() {
                @Override
                public void run() {
                    //my methods
                }
            });
        }
    });

还有我的 Looper Class:

class LooperThread extends Thread {
    Handler handler;
    public void run() {
        Looper.prepare();
        handler = new Handler();
        Looper.loop();
    }
}

如果是, 问题是这样,我不明白为什么系统在我输入时不识别 "handler":"myThread.handler.post.." 和 运行 方法。

不然你能帮我做这个吗?

如果我在提问时犯了错误,我很抱歉,但这是我第一次来:)``

欢迎来到 Stack Overflow。

I would like to be able to run my specific method in background through a looper in an on click event, is this the right way to do this?

您的代码有效,但我不能说这是正确的方法。就像@tynn 提到的那样,HandlerThread 可能是更好的选择。

If it is, the problem is that in this way, i don't understand why the system don't recognize "handler" while i typing: "myThread.handler.post.." and run the methods.

Otherwise, can you help me on making this?

如果我理解你的问题,那就是访问问题。您的处理程序似乎无法访问,因为它被声明为包私有的。您可以通过这种方式让您的处理程序可见:

// Should this class be public or package-private?
public class LooperThread extends Thread {

    private Handler handler;

    public Handler getHandler() {
        return handler;
    }

    // ...
}

您将能够像这样引用处理程序:

myThread.getHandler().post(...);

更新

您可以这样延迟 Runnable 执行:

// Delay execution of a Runnable task by 5000 milliseconds.
myThread.getHandler().postDelayed(myDelayedRunnable, 5000);
