NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
以一個(gè)為例
Notification notify3 = new Notification.Builder(this) .setSmallIcon(R.drawable.ic_launcher) //icon的圖片設(shè)置 .setTicker("TickerText:" + "您有新短消息，請(qǐng)注意查收！")//提醒的類(lèi)容 .setContentTitle("Notification Title")//提醒的標(biāo)題 .setContentText("This is the notification message")/提醒類(lèi)容 .setContentIntent(pendingIntent3).setNumber(1).build();
PendingIntent//跳轉(zhuǎn)界面 傳遞信息用的
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有一個(gè)getActivity方法，第一個(gè)參數(shù)是上下文，第二個(gè)參數(shù) requestCode，第三個(gè)參數(shù)是 Intent，用來(lái)存儲(chǔ)信息，第四個(gè)參數(shù)是對(duì)參數(shù)的操作標(biāo)識(shí)，常用的就是FLAG_CANCEL_CURRENT和FLAG_UPDATE_CURRENT。
關(guān)于第二個(gè)參數(shù)當(dāng)requestCode值一樣時(shí)，后面的就會(huì)對(duì)之前的消息起作用，所以為了避免影響之前的消息，requestCode每次要設(shè)置不同的內(nèi)容。
myNotify = new Notification();myNotify.flags = Notification.FLAG_NO_CLEAR;// 不能夠自動(dòng)清除 myNotify.defaults = Notification.DEFAULT_ALL; // 使用默認(rèn)設(shè)置，比如鈴聲、震動(dòng)、閃燈 myNotify.flags = Notification.FLAG_AUTO_CANCEL; // 但用戶點(diǎn)擊消息后，消息自動(dòng)在通知欄自動(dòng)消失
//DEFAULT_ALL 使用所有默認(rèn)值，比如聲音，震動(dòng)，閃屏等等//DEFAULT_LIGHTS 使用默認(rèn)閃光提示//DEFAULT_SOUNDS 使用默認(rèn)提示聲音//DEFAULT_VIBRATE 使用默認(rèn)手機(jī)震動(dòng)，需加上<uses-permission android:name="android.permission.VIBRATE" />權(quán)限myNotify.defaults = Notification.DEFAULT_LIGHTS;//閃光和震動(dòng)需要添加權(quán)限
<!-- 閃光燈權(quán)限 --><uses-permission android:name="android.permission.FlashLIGHT"><!-- 振動(dòng)器權(quán)限 --><uses-permission android:name="android.permission.VIBRATE"></uses-permission></uses-permission> |
notifyBuilder.setPRogress(100, incr, false);這個(gè)設(shè)置滾動(dòng)條可以寫(xiě)帶滾動(dòng)條的提示
/** * 帶滾動(dòng)條的提示 */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:您有新下載消息，請(qǐng)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類(lèi)型是提示信息的表示重復(fù)不會(huì)彈出顯示
