《第一行代码》第8章 --通知的使用修正

《第一行代码》第8章的中涉及的通知的基本用法处，由于Notificition已被弃用，所以代码出错。需要更新写法。下面列出的是可用的修正写法。同时，第九章P365页处用到的通知，也需要重新写。

##1、P300 页源码及修正

@Override
    private void onClick(View v){
        switch (v.getId()){
            case R.id.send_notice:
                NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                Notification notification = new Notification(R.drawable.s3,"this is ticker text",
                                                                     System.currentTimeMillis());
                notification.setLatestEventInfo(this,"this is title","this is text",null);
                manager.notify(1,notification);
                break;
            default:
                break;
        }
    }

更新为

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.send_notice:
            NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
            builder.setSmallIcon(R.drawable.s3);
            builder.setTicker("just watch me");
            builder.setWhen(System.currentTimeMillis());
            builder.setContentTitle("look at that");
            builder.setContentText("you can do it!");
            Intent intent = new Intent(this,NotificationActivity.class);
            PendingIntent pi = PendingIntent.getActivity(this,0,intent,
                                    PendingIntent.FLAG_CANCEL_CURRENT);
            builder.setContentIntent(pi);

            //Uri soundUri = Uri.fromFile(new File("/system/media/audio/ringtones/Basic_tone.ogg"));
            //builder.setSound(soundUri);

            //long[] vibrates = {0,1000,1000,1000};
            //builder.setVibrate(vibrates);

            //builder.setLights(Color.GREEN,1000,1000);
            builder.setDefaults(Notification.DEFAULT_ALL);
            manager.notify(1, builder.build());
            break;
        default:
            break;

##2、P365 页源码及修正

Notification notification = new Notification(R.drawable.a10,"Notification comes",
                System.currentTimeMillis());
        Intent notificationIntent = new Intent(this,MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,notificationIntent,0);
        notification.setLatestEventInfo(this,"this is title","this is content",pendingIntent);
        startForeground(1,notification);
        Log.d("MyService","onCreate executed");

更新为：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setSmallIcon(R.mipmap.ic_launcher);
        builder.setTicker("just watch me");
        builder.setWhen(System.currentTimeMillis());
        builder.setContentTitle("look at that");
        builder.setContentText("you can do it!");
        startForeground(1,builder.build());
