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

 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

notificationmanager = (notificationmanager) context.getsystemservice(context.notification_service);
notificationmanager.notify(notifyid, notification);

3.手机震动提醒

/**
   * 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

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
}
