Android实战Service BroadcastReceiver与AlarmManager

public IBinder onBind(Intent intent) {

return null;

}

}

完成了Service，之后就是写一个Activity来启动这个Service，其中为了保证在应用退出后Servcie继续运行，所以要使用startService()来启动Service。一般关于Service的资料上都是有的。

package com.shinestudio.sleepMusic;

import java.util.Iterator;

import java.util.List;

//......

import com.shinestudio.sleepMusic.service.ISleepMusicService;

import com.shinestudio.sleepMusic.service.SleepMusicService;

import com.shinestudio.sleepMusic.unit.TimerPickerUIStruct;

public class StartActivity extends Activity {

private static String TAG = "sleepMusic - StartActivity";

private ListView timerlist;

private TimerPicker timerPicker;

private TimerPickerUIStruct tpui;

private Button startButton;

private Button cancelButton;

private Button restartButton;

//当点击开始按钮

private OnClickListener startButtonClickListener = new OnClickListener() {

@Override

public void onClick(View v) {

Intent isleepMusicService = new Intent(StartActivity.this,

SleepMusicService.class);

/*

在Service启动之前可以使用Intent来传递参数给Service ，方法如下

目前的代码只是演示，与功能无关

*/

Bundle setting = new Bundle();

setting.putString(“TIME_SETTING”, "5s");

// 在Service中使用“TIME_SETTING”这个标签就可以从Intent取出5s 这个字符串了

isleepMusicService.putExtras(setting);

startService(isleepMusicService);

}

};

//点击取消按钮

private OnClickListener cancelButtonClickListener = new OnClickListener() {

@Override

public void onClick(View v) {

Intent sleepMusicService = new Intent(StartActivity.this,
