Android 通知栏Notification的整合

功能作用

1.显示接收到短消息、即使消息等信息 （如QQ、微信、新浪、短信）  2.显示客户端的推送消息（如有新版本发布，广告，推荐新闻等） 3.显示正在进行的事物（例如：后台运行的程序）（如音乐播放器、版本更新时候的下载进度等）元素：1. 标题   Title/Name2. 大图标 Icon/Photo3. 内容文字   4. 内容信息   MESSAGE5. 小图标 SecondaryIcon6. 通知的时间 Timestamp,默认为系统发出通知的时间，也可通过setWhen()来设置状态通知栏主要涉及到2个类：  Notification 和 NotificationManager Notification为通知信息类，它里面对应了通知栏的各个属性NotificationManager ：  是状态栏通知的管理类，负责发通知、清除通知等操作。注意：NotificationManager 是一个系统Service，所以必须通过 

getSystemService(NOTIFICATION_SERVICE)方法来获取，方法如下。

NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  

第一步：获取状态通知栏管理：[java]view plaincopy NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  第二步：实例化通知栏构造器NotificationCompat.Builder：[java]view plaincopy NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);  第三步：对Builder进行配置：mBuilder.setContentTitle("测试标题")//设置通知栏标题      .setContentText("测试内容") /<span style="font-family: Arial;">/设置通知栏显示内容</span>      .setContentIntent(getDefalutIntent(Notification.FLAG_AUTO_CANCEL)) //设置通知栏点击意图  //  .setNumber(number) //设置通知集合的数量      .setTicker("测试通知来啦") //通知首次出现在通知栏，带上升动画效果的      .setWhen(System.currentTimeMillis())//通知产生的时间，会在通知信息里显示，一般是系统获取到的时间      .setPriority(Notification.PRIORITY_DEFAULT) //设置该通知优先级  //  .setAutoCancel(true)//设置这个标志当用户单击面板就可以让通知将自动取消        .setOngoing(false)//ture，设置他为一个正在进行的通知。他们通常是用来表示一个后台任务,用户积极参与(如播放音乐)或以某种方式正在等待,因此占用设备(如一个文件下载,同步操作,主动网络连接)      .setDefaults(Notification.DEFAULT_VIBRATE)//向通知添加声音、闪灯和振动效果的最简单、最一致的方式是使用当前的用户默认设置，使用defaults属性，可以组合      //Notification.DEFAULT_ALL  Notification.DEFAULT_SOUND 添加声音 // requires VIBRATE permission      .setSmallIcon(R.drawable.ic_launcher);//设置通知小ICON     第一步：获取状态通知栏管理：[java]view plaincopy NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  第二步：实例化通知栏构造器NotificationCompat.Builder：[java]view plaincopy NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);  第三步：对Builder进行配置：  mBuilder.setContentTitle("测试标题")//设置通知栏标题      .setContentText("测试内容") /<span style="font-family: Arial;">/设置通知栏显示内容</span>      .setContentIntent(getDefalutIntent(Notification.FLAG_AUTO_CANCEL)) //设置通知栏点击意图  //  .setNumber(number) //设置通知集合的数量      .setTicker("测试通知来啦") //通知首次出现在通知栏，带上升动画效果的      .setWhen(System.currentTimeMillis())//通知产生的时间，会在通知信息里显示，一般是系统获取到的时间      .setPriority(Notification.PRIORITY_DEFAULT) //设置该通知优先级  //  .setAutoCancel(true)//设置这个标志当用户单击面板就可以让通知将自动取消        .setOngoing(false)//ture，设置他为一个正在进行的通知。他们通常是用来表示一个后台任务,用户积极参与(如播放音乐)或以某种方式正在等待,因此占用设备(如一个文件下载,同步操作,主动网络连接)      .setDefaults(Notification.DEFAULT_VIBRATE)//向通知添加声音、闪灯和振动效果的最简单、最一致的方式是使用当前的用户默认设置，使用defaults属性，可以组合      //Notification.DEFAULT_ALL  Notification.DEFAULT_SOUND 添加声音 // requires VIBRATE permission      .setSmallIcon(R.drawable.ic_launcher);//设置通知小ICON     详细代码：/**      * 带按钮的通知栏      */      public void showButtonNotify(){          NotificationCompat.Builder mBuilder = new Builder(this);          RemoteViews mRemoteViews = new RemoteViews(getPackageName(), R.layout.view_custom_button);          mRemoteViews.setImageViewResource(R.id.custom_song_icon, R.drawable.sing_icon);          //API3.0 以上的时候显示按钮，否则消失          mRemoteViews.setTextViewText(R.id.tv_custom_song_singer, "周杰伦");          mRemoteViews.setTextViewText(R.id.tv_custom_song_name, "七里香");          //如果版本号低于（3。0），那么不显示按钮          if(BaseTools.getSystemVersion() <= 9){              mRemoteViews.setViewVisibility(R.id.ll_custom_button, View.GONE);          }else{              mRemoteViews.setViewVisibility(R.id.ll_custom_button, View.VISIBLE);          }          //          if(isPlay){              mRemoteViews.setImageViewResource(R.id.btn_custom_play, R.drawable.btn_pause);          }else{              mRemoteViews.setImageViewResource(R.id.btn_custom_play, R.drawable.btn_play);          }          //点击的事件处理          Intent buttonIntent = new Intent(ACTION_BUTTON);          /* 上一首按钮 */          buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_PREV_ID);          //这里加了广播，所及INTENT的必须用getBroadcast方法          PendingIntent intent_prev = PendingIntent.getBroadcast(this, 1, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);          mRemoteViews.setOnClickPendingIntent(R.id.btn_custom_prev, intent_prev);          /* 播放/暂停  按钮 */          buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_PALY_ID);          PendingIntent intent_paly = PendingIntent.getBroadcast(this, 2, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);          mRemoteViews.setOnClickPendingIntent(R.id.btn_custom_play, intent_paly);          /* 下一首 按钮  */          buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_NEXT_ID);          PendingIntent intent_next = PendingIntent.getBroadcast(this, 3, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);          mRemoteViews.setOnClickPendingIntent(R.id.btn_custom_next, intent_next);                    mBuilder.setContent(mRemoteViews)                  .setContentIntent(getDefalutIntent(Notification.FLAG_ONGOING_EVENT))                  .setWhen(System.currentTimeMillis())// 通知产生的时间，会在通知信息里显示                  .setTicker("正在播放")                  .setPriority(Notification.PRIORITY_DEFAULT)// 设置该通知优先级                  .setOngoing(true)                  .setSmallIcon(R.drawable.sing_icon);          Notification notify = mBuilder.build();          notify.flags = Notification.FLAG_ONGOING_EVENT;          mNotificationManager.notify(notifyId, notify);      }
