Question

几个月前，我编写了一个代码，我Notification的工作方式如下：

NotificationManager NotiManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
String MyText = "NotificationText";
Notification mNotification = new Notification(R.mipmap.icon, MyText, System.currentTimeMillis() );

mNotification.flags |= Notification.FLAG_AUTO_CANCEL;
mNotification.defaults |= Notification.DEFAULT_SOUND;
mNotification.defaults |= Notification.DEFAULT_VIBRATE;

String MyNotificationTitle = "AnyText";
String MyNotificationText  = "HERE MORE TEXT";
Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://www.google.com"));
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent StartIntent = PendingIntent.getActivity(context.getApplicationContext(), 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
mNotification.setLatestEventInfo(context.getApplicationContext(), MyNotificationTitle, MyNotificationText, StartIntent);
NotiManager.notify(NOTIFY_ME_ID_LOGIN, mNotification);

但是现在，我想要进行更新，它甚至不会编译APP，因为这一行：

mNotification.setLatestEventInfo(context.getApplicationContext(), MyNotificationTitle, MyNotificationText, StartIntent);

有没有办法更改setLatestEventInfo或其他方式来创建Notification？

Answer 1

有没有办法改变setLatestEventInfo

欢迎您降低compileSdkVersion，但这会引入一系列问题。

或其他创建通知的方式？

正如Blackbelt在评论中指出的那样，NotificationCompat.Builder已存在约4年，是今天创建Notification个对象的推荐方法：

  private void raiseNotification(String mimeType, File output,
                                 Exception e) {
    NotificationCompat.Builder b=new NotificationCompat.Builder(this);

    b.setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL);

    if (e == null) {
      b.setContentTitle(getString(R.string.download_complete))
       .setContentText(getString(R.string.fun))
       .setSmallIcon(android.R.drawable.stat_sys_download_done)
       .setTicker(getString(R.string.download_complete));

      Intent outbound=new Intent(Intent.ACTION_VIEW);

      outbound.setDataAndType(Uri.fromFile(output), mimeType);

      b.setContentIntent(PendingIntent.getActivity(this, 0, outbound, 0));
    }
    else {
      b.setContentTitle(getString(R.string.exception))
       .setContentText(e.getMessage())
       .setSmallIcon(android.R.drawable.stat_notify_error)
       .setTicker(getString(R.string.exception));
    }

    NotificationManager mgr=
        (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

    mgr.notify(NOTIFY_ID, b.build());
  }
