Notification的基本使用

        // 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);

以一个为例

  Notification notify3 = new Notification.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher)  //icon的图片设置
                        .setTicker("TickerText:" + "您有新短消息，请注意查收！")//提醒的类容
                        .setContentTitle("Notification Title")//提醒的标题
                        .setContentText("This is the notification message")/提醒类容
                        .setContentIntent(pendingIntent3).setNumber(1).build();

PendingIntent//跳转界面  传递信息用的

示例

 intent1 = new Intent(getApplicationContext(),
                        ContentActivity.class);
                intent1.putExtra("content", "444");
                intent1.putExtra("number", "444");
                intent1.putExtra("date", "444");
         PendingIntent        contentIntent = PendingIntent.getActivity(this, 1,
                   intent1, PendingIntent.FLAG_CANCEL_CURRENT);

PendingIntent有一个getActivity方法，第一个参数是上下文，第二个参数 requestCode，第三个参数是 Intent，用来存储信息，第四个参数是对参数的操作标识，常用的就是FLAG_CANCEL_CURRENT和FLAG_UPDATE_CURRENT。

关于第二个参数当requestCode值一样时，后面的就会对之前的消息起作用，所以为了避免影响之前的消息，requestCode每次要设置不同的内容。

myNotify = new Notification();

myNotify.flags = Notification.FLAG_NO_CLEAR;// 不能够自动清除
                myNotify.defaults = Notification.DEFAULT_ALL; // 使用默认设置，比如铃声、震动、闪灯
                myNotify.flags = Notification.FLAG_AUTO_CANCEL; // 但用户点击消息后，消息自动在通知栏自动消失

  //DEFAULT_ALL     使用所有默认值，比如声音，震动，闪屏等等

  //DEFAULT_LIGHTS  使用默认闪光提示

  //DEFAULT_SOUNDS  使用默认提示声音

   //DEFAULT_VIBRATE 使用默认手机震动，需加上<uses-permission android:name="android.permission.VIBRATE" />权限

  myNotify.defaults = Notification.DEFAULT_LIGHTS;




//闪光和震动需要添加权限

<!-- 闪光灯权限 -->

<uses-permission android:name="android.permission.FLASHLIGHT">

<!-- 振动器权限 -->

<uses-permission android:name="android.permission.VIBRATE"></uses-permission></uses-permission>

notifyBuilder.setProgress(100, incr, false);

这个设置滚动条

可以写带滚动条的提示

/** * 带滚动条的提示 */public void Pro_Notification() {    manager_n = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);     notifyBuilder = new NotificationCompat.Builder(this);    notifyBuilder.setContentTitle("Picture Download")            .setContentText("Download in progress")            .setTicker("TickerText:您有新下载消息，请注意查收！")            .setOngoing(true)            .setSmallIcon(R.drawable.ic_launcher);    // Start a lengthy operation in a background thread    new Thread(            new Runnable() {                @Override                public void run() {                    int incr;                    // Do the "lengthy" operation 20 times                    for (incr = 0; incr <= 100; incr += 5) {                        // Sets the progress indicator to a max value, the                        // current completion percentage, and "determinate"                        // state                        notifyBuilder.setProgress(100, incr, false);                        // Displays the progress bar for the first time.                        manager_n.notify(0, notifyBuilder.build());                        // Sleeps the thread, simulating an operation                        // that takes time                        try {                            // Sleep for 5 seconds                            Thread.sleep( 1000);                        } catch (InterruptedException e) {                            Log.d("NOTIFICATION", "sleep failure");                        }                    }                    // When the loop is finished, updates the notification                    notifyBuilder.setContentText("Download complete")                            // Removes the progress bar                            .setProgress(0, 0, false);                    manager_n.notify(213, notifyBuilder.build());                }            }            // Starts the thread by calling the run() method in its Runnable    ).start();}

   manager.notify(NOTIFICATION_FLAG, notify2);中的NOTIFICATION_FLAG是int类型是提示信息的表示重复不会弹出显示
