从服务中使用处理器更新活动 [英] Update Activity from service using handler

问题描述

我想改变状态的切换按钮在我的活动当事件在服务发生。任何人都可以请帮我实现这个使用的处理程序？ 我的意思是我应该在哪里写的code创建的处理程序以及如何从一个服务触发了吗？我读了类似的帖子，但是，他们并没有真正有助于实现这一目标。

I want change the state of a ToggleButton in my Activity when an event occurs in a service. Can anybody please help me to implement this using Handler? I mean where should I write the code to create the handler and how to trigger it from a service? I read similar posts but, they were not really helpful in achieving this.

推荐答案

在你的Activity

In your Activity

public class MyActivity extends Activity {
    public static Runnable runnable;
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

           runnable=new Runnable(){

            @Override
            public void run() {
            //Change status here

            }

           };

从服务

Handler handler=new Handler();
handler.post(MyActivity.runnable);
