今天总结了一下Notification的使用,与大家分享一下。

MainActivity.java:

本文参考:,

public class MainActivity extends Activity {
private Button btn; private NotificationManager manager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);// showNotification();// showNotification2();// showNotification3();// showNotification4();// showNotification5(); showNotification6(); this.btn = (Button) this.findViewById(R.id.button1); this.btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { clearNotification(); } }); } /** * 自定义Notification布局 */ private void showNotification6() { RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.custom_notification); Intent intent = new Intent(this, SecondActivity.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0); //点击时给SecondActivity发送一条广播 remoteViews.setOnClickPendingIntent(R.id.paly_pause_music, pendingIntent); Intent intent1 = new Intent(this,SecondActivity.class); remoteViews.setOnClickPendingIntent(R.id.paly_pause_music, PendingIntent.getActivity(this, 0, intent1, 0)); NotificationCompat.Builder builder = new Builder(this); builder.setContent(remoteViews).setSmallIcon(R.drawable.ic_launcher) .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)).setOngoing(true) .setTicker("music is playing"); manager.notify(0, builder.build()); } /** * 大布局Picture类型notification * 这个方法貌似还有一点问题 */ private void showNotification5() { NotificationCompat.BigPictureStyle pictureStyle = new BigPictureStyle(); pictureStyle.setBigContentTitle("BigContentTitle") .setSummaryText("Summary Text").bigPicture(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)); Notification notification = new NotificationCompat.Builder(this) .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)) .setTicker("showBigView_pic").setContentInfo("ContentInfo") .setContentTitle("ContentTitle").setContentText("ContentText") .setStyle(pictureStyle) .setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL) .build(); manager.notify(3, notification); } /** * 带进度条的通知栏 */ private void showNotification4() { final NotificationCompat.Builder builder = new NotificationCompat.Builder(this); builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)) .setSmallIcon(R.drawable.ic_launcher) .setTicker("showProgressBar") .setContentInfo("ContentInfo") .setOngoing(true) .setContentTitle("ContentTitle") .setContentText("ContentText"); new Thread(new Runnable() { @Override public void run() { int progress = 0; for(progress=0;progress<100;progress+=5){ //将第三个参数改为true,进度条会变为无明显进度的样式 builder.setProgress(100, progress, true); manager.notify(0, builder.build()); try { Thread.sleep(1000); } catch (Exception e) { } } //线程执行完毕之后,修改通知栏的显示 builder.setContentTitle("Download complete").setProgress(0, 0, false).setOngoing(false); manager.notify(0, builder.build()); } }).start(); } /** * 大通知栏 */ private void showNotification3() { NotificationCompat.BigTextStyle textStyle = new BigTextStyle(); textStyle.setBigContentTitle("BigContentTitle") .setSummaryText("Summary Text") .bigText("I'm Big Text......................................................................"); Notification notification = new NotificationCompat.Builder(this) .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)) .setSmallIcon(R.drawable.ic_launcher) .setTicker("Ticker") .setContentInfo("ContentInfo") .setContentTitle("ContentTitle") .setContentText("ContentText") .setStyle(textStyle) .setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL).build(); manager.notify(0, notification); } /** * 小通知栏 */ private void showNotification2() { Notification notification = new NotificationCompat.Builder(this) .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)) .setSmallIcon(R.drawable.ic_launcher) .setTicker("showNormal") .setContentInfo("ContextInfo") .setContentTitle("ContentTitle") .setContentText("ContentText") .setNumber(45) .setAutoCancel(true) .setDefaults(Notification.DEFAULT_ALL) .build(); Intent notificationIntent =new Intent(MainActivity.this, SecondActivity.class); PendingIntent contentItent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.contentIntent=contentItent; manager.notify(0, notification); } /** * 在状态栏显示通知 */ private void showNotification(){ // 创建一个NotificationManager的引用 NotificationManager notificationManager = (NotificationManager) this.getSystemService(android.content.Context.NOTIFICATION_SERVICE); // 定义Notification的各种属性 Notification notification =new Notification(R.drawable.ic_launcher, "系统测试", System.currentTimeMillis()); //FLAG_AUTO_CANCEL 该通知能被状态栏的清除按钮给清除掉 //FLAG_NO_CLEAR 该通知不能被状态栏的清除按钮给清除掉 //FLAG_ONGOING_EVENT 通知放置在正在运行 //FLAG_INSISTENT 是否一直进行,比如音乐一直播放,知道用户响应// notification.flags |= Notification.FLAG_ONGOING_EVENT; // 将此通知放到通知栏的"Ongoing"即"正在运行"组中 // notification.flags |= Notification.FLAG_NO_CLEAR; // 表明在点击了通知栏中的"清除通知"后,此通知不清除,经常与FLAG_ONGOING_EVENT一起使用 notification.flags |= Notification.FLAG_AUTO_CANCEL; notification.flags |= Notification.FLAG_SHOW_LIGHTS; //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
权限 notification.defaults = Notification.DEFAULT_LIGHTS; //叠加效果常量 //notification.defaults=Notification.DEFAULT_LIGHTS|Notification.DEFAULT_SOUND; notification.ledARGB = Color.BLUE; notification.ledOnMS =5000; //闪光时间,毫秒 // 设置通知的事件消息 CharSequence contentTitle ="系统消息"; // 通知栏标题 CharSequence contentText ="系统正在运行...."; // 通知栏内容 Intent notificationIntent =new Intent(MainActivity.this, SecondActivity.class); // 点击该通知后要跳转的Activity PendingIntent contentItent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(this, contentTitle, contentText, contentItent); // 把Notification传递给NotificationManager notificationManager.notify(0, notification); } //删除通知 private void clearNotification(){ // 启动后删除之前我们定义的通知 NotificationManager notificationManager = (NotificationManager) this .getSystemService(NOTIFICATION_SERVICE); notificationManager.cancel(0); }}

关键代码文中已有注释,。如有错误之后欢迎大家一起讨论。
