Android8.0通知栏适配

String channelId="channel_id";
NotificationManager manager=getSystemService(Context.NOTIFICATION_SERVICE);

if(Build.VERSION.SDK_INT>=BUILD.VERSION_CODES.O){
    Charsequence name="channel_name";
    String description="channel_description";
    int importance=NotificationManager.IMPORTANCE_DEFAULT;//根据项目的自行选择
    NotificationChannel channel=new NotificationChannel(channelId,name,importance);
    channel.setDescription(description);
    manager.createNotificationChannel(channel);
}

Intent intent=new Intent(MainActivity.this,NotificationActivity.class);
PendingIntent pendingIntent=PendingIntent.getActivity(Mainactivity.this,0,intent,0);
Notification notification=new NotificationCompat.Builder(MainActivity.this,channelId)
    .setContentTitle("This is a title")
    .setContentText("This is a text")
    .setWhen(System.currentTimeMillis())
    .setSmallIcon(R.drawable.notification_icon)
    .setLargeIcon(BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher)
                  .setChannelId(channelId)
                  .setContentIntent(pendingIntent)
                  .setStyle(new NotificationCompat.BigTextStyle().bigText("Learn how to build notifications,send and sync data,and use voice actions.Get the official Adnroid IDE and developers tools to build app for Android."))
                  .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(BitmapFactory.decodeResource(getResources(),R.drawable.add_data-img)))
                  .setAutoCancel(true)
                  .build();
                  manager.notify(234,notification);

即使是在服务中，也需要有之前的步骤。
