我如何获得一个Android服务广播每隔几秒钟的意图是什么？ [英] How do I get an Android service to broadcast an intent every few seconds?

问题描述

如果我创建了一个服务，我怎么得到它播出的意图每X秒？我记得沿线看到code的片段

If I've created a service, how do I get it to broadcast an intent every X seconds? I remember seeing a snippet of code along the lines

startThreadDelayed( new Thread() {
    public void run() {
        doStuff();
        sendBroadcast(messageIntent);
        startThreadDelayed(this, 1000);
    }
}, 1000);

可惜的是我不知道任何类名，或者确切的方法名，无论是循环的。只是一个名字就点我的寻找正确的方向。

Unfortunatelly I'm not sure of either the class name, or the exact method name, for whatever is looping. Just a name would point me in the right direction of searching.

推荐答案

您可以使用 Handler.postDelayed 。 <一href=\"http://developer.android.com/reference/android/os/Handler.html#postDelayed%28java.lang.Runnable,%20long%29\"相对=nofollow>这里的文档。

例如

Handler h = new Handler();
YourClass yourRunnable = new YourClass();
h.postDelayed(youRunnable,1000);


public class YourClass implements Runnable{
    public void run(){
    doStuff();
    sendBroadcast(messageIntent);
    if(running)
        h.postDelayed(youRunnable,1000);
}

跑这里是一个标志，较好地保持它作为挥发性布尔值。因此，通过改变它的价值，你可以停止repeatition。

here running is a flag better keep it as volatile boolean. So that by changing it's value you can stop the repeatition.
