通知欄Notification基本使用

NotificationManager manager= (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notification=new NotificationCompat.Builder(MainActivity.this)
                        .setContentTitle("标題")//标題
                        .setContentText("内容")//内容
                        .setSmallIcon(R.mipmap.ic_launcher)//圖示
                        .build();
                manager.notify(1,notification);
