Android Notification使用方法总结

Android Notification使用方法总结

一. 基本使用

1.构造notification

代码语言：javascript复制

 NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(appContext)
          .setSmallIcon(appContext.getApplicationInfo().icon)
          .setWhen(System.currentTimeMillis())
          .setAutoCancel(true)//当点击通知的时候会自动取消
          .setContentTitle(contentTitle)
          .setTicker(notifyText)//状态栏提示
          .setContentText(summaryBody)
          .setContentIntent(pendingIntent)
          .setNumber(notificationNum);
      Notification notification = mBuilder.build();

2.显示通知

代码语言：javascript复制

notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notifyID, notification);

3.手机震动提醒

代码语言：javascript复制

/**
   * 手机震动和声音提示
   */
  public void viberateAndPlayTone(EMMessage message) {
    if(message != null){
      if(EMChatManager.getInstance().isSlientMessage(message)){
        return;
      } 
    }


    if (System.currentTimeMillis() - lastNotifiyTime < 1000) {
      // received new messages within 2 seconds, skip play ringtone
      return;
    }

    try {
      lastNotifiyTime = System.currentTimeMillis();

      // 判断是否处于静音模式
      if (audioManager.getRingerMode() == AudioManager.RINGER_MODE_SILENT) {
        EMLog.e(TAG, "in slient mode now");
        return;
      }
      EaseSettingsProvider settingsProvider = EaseUI.getInstance().getSettingsProvider();
      if(settingsProvider.isMsgVibrateAllowed(message)){//检测是否允许震动
        long[] pattern = new long[] { 0, 180, 80, 120 };
        vibrator.vibrate(pattern, -1);
      }

      if(settingsProvider.isMsgSoundAllowed(message)){//检测是否允许声音
        if (ringtone == null) {
          Uri notificationUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);//获取系统默认通知铃声

          ringtone = RingtoneManager.getRingtone(appContext, notificationUri);
          if (ringtone == null) {
            EMLog.d(TAG, "cant find ringtone at:"   notificationUri.getPath());
            return;
          }
        }

        if (!ringtone.isPlaying()) {//防止响铃叠加
          String vendor = Build.MANUFACTURER;

          ringtone.play();
          // for samsung S3, we meet a bug that the phone will
          // continue ringtone without stop
          // so add below special handler to stop it after 3s if
          // needed
          if (vendor != null && vendor.toLowerCase().contains("samsung")) {
            Thread ctlThread = new Thread() {
              public void run() {
                try {
                  Thread.sleep(3000);
                  if (ringtone.isPlaying()) {
                    ringtone.stop();
                  }
                } catch (Exception e) {
                }
              }
            };
            ctlThread.run();
          }
        }
      }
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

4.取消Notification

代码语言：javascript复制

void cancelNotificaton() {
    if (notificationManager != null)
    notificationManager.cancel(notifyID);//根据ID取消，每个Notification都有唯一的ID。一般在Activity的基类的onResume调用。这样可以达到进入程序后，通知自动取消的效果
}
