（4.3.1.2）【项目一】主体框架Fragment中启动Service与notification的使用

创建Service

public class MyService extends Service {

public static final String TAG = "MyService";

@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "onCreate() executed");
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d(TAG, "onStartCommand() executed");
return super.onStartCommand(intent, flags, startId);
}

@Override
public void onDestroy() {
super.onDestroy();
Log.d(TAG, "onDestroy() executed");
}

@Override
public IBinder onBind(Intent intent) {
return null;
}

}

生成notification

// 在Android进行通知处理，首先需要重系统哪里获得通知管理器NotificationManager，它是一个系统Service。
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification myNotify = new Notification();
notify1.setLatestEventInfo(this, "Notification Title",
"This is the notification message", pendingIntent);
manager.notify(NOTIFICATION_FLAG, notify1);

示例

package com.android.yunshi.service;

//每日运程的信息推送
import android.app.Service;
import java.util.Calendar;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

import com.android.yunshi.LogoActivity;
import com.android.yunshi.R;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.IBinder;
import android.util.Log;
import android.widget.RemoteViews;

public class DailyYunChengTuiSong extends Service {

public Timer timer;
final String TAG = "com.yhf.dailyyunchengtuisong";
int CUSTOM_VIEW_ID = 1;// 通知的id号
Calendar calendar;// 时间类，设定timer.schedule的执行时间
Boolean isyunchengtuisong_Done;

@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
Log.i(TAG, "onBind");
return null;
}

@Override
public boolean onUnbind(Intent intent) {
// TODO Auto-generated method stub
Log.i(TAG, "onUnbind");
return super.onUnbind(intent);
}

@Override
public void onRebind(Intent intent) {
// TODO Auto-generated method stub
super.onRebind(intent);
Log.i(TAG, "onRebind");
}

@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
Log.i(TAG, "onCreate");
timer = new Timer(true);// 当程序只有daemon线程的时候，它就会自动终止运行。
}

@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Log.i(TAG, "onDestroy");
}

@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Log.i(TAG, "onStart");

// 设定执行时间为10:21分
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Date time = calendar.getTime();
// chedule方法，
// 第一个参数是TimerTask对象
// 第二个参数表示开始执行前的延时时间,或者定时
timer.schedule(new TimerTask() {
public void run() {
int icon = R.drawable.yunshi360;
CharSequence tickerText = "运势360";

Intent notificationIntent = new Intent(
DailyYunChengTuiSong.this, LogoActivity.class);
PendingIntent contentIntent = PendingIntent
.getActivity(DailyYunChengTuiSong.this, 0,
notificationIntent, 0);
notification.contentIntent = contentIntent;

notification.flags = Notification.FLAG_AUTO_CANCEL;// 点击后自动消失
// 也可设置为不消失
notification.defaults =Notification.DEFAULT_SOUND;
/*

* 添加声音

* notification.defaults |=Notification.DEFAULT_SOUND;

* 或者使用以下几种方式

* notification.sound = Uri.parse("file:///sdcard/notification/ringer.mp3");

* notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");

* 如果想要让声音持续重复直到用户对通知做出反应，则可以在notification的flags字段增加"FLAG_INSISTENT"

* 如果notification的defaults字段包括了"DEFAULT_SOUND"属性，则这个属性将覆盖sound字段中定义的声音

*/

/*

* 添加振动

* notification.defaults |= Notification.DEFAULT_VIBRATE;

* 或者可以定义自己的振动模式：

* long[] vibrate = {0,100,200,300}; //0毫秒后开始振动，振动100毫秒后停止，再过200毫秒后再次振动300毫秒

* notification.vibrate = vibrate;

* long数组可以定义成想要的任何长度

* 如果notification的defaults字段包括了"DEFAULT_VIBRATE",则这个属性将覆盖vibrate字段中定义的振动

*/

/*

* 添加LED灯提醒

* notification.defaults |= Notification.DEFAULT_LIGHTS;

* 或者可以自己的LED提醒模式:

* notification.ledARGB = 0xff00ff00;

* notification.ledOnMS = 300; //亮的时间

* notification.ledOffMS = 1000; //灭的时间

* notification.flags |= Notification.FLAG_SHOW_LIGHTS;

*/

// 停止服务
// 服务停止的时间不确定，后面的代码还是会执行，并且onDestroy()方法也会执行，
// 下次重新启动服务的时候，先调用onCreate(),然后再调用onStart()方法。

注册Service

<service android:name="com.android.yunshi.service.DailyYunChengTuiSong" >
<intent-filter>
<action android:name="com.yhf.dailyyunchengtuisong" >
</action>

<category android:name="android.intent.category.default" />
</intent-filter>
</service>

启动Service

intent.setAction("com.yhf.dailyyunchengtuisong");
startService(intent);
