Question

当我尝试在API级别19

中使用它时，我得到了he constructor Notification(int, CharSequence, long) is deprecated

对于通知我做了如下代码

@Override
 public void onReceive(Context context, Intent intent) {
  nm = (NotificationManager) context
    .getSystemService(Context.NOTIFICATION_SERVICE);
  CharSequence from = "Nithin";
  CharSequence message = "Crazy About Android...";
  PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
    new Intent(), 0);
  Notification notif = new Notification(R.drawable.icon,
    "Crazy About Android...", System.currentTimeMillis());
  notif.setLatestEventInfo(context, from, message, contentIntent);
  nm.notify(1, notif);
 }

AlarmManager am ;
      public void setOneTimeAlarm() {
          Intent intent = new Intent(this, TimeAlarm.class);
          PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
            intent, PendingIntent.FLAG_ONE_SHOT);
          am.set(AlarmManager.RTC_WAKEUP,
            System.currentTimeMillis() + (5 * 1000), pendingIntent);
         }

         public void setRepeatingAlarm() {
          Intent intent = new Intent(this, TimeAlarm.class);
          PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
            intent, PendingIntent.FLAG_CANCEL_CURRENT);
          am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
            (5 * 1000), pendingIntent);
         }

Inside onCreate(Bundle SavedInstanceState){
    am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
          setOneTimeAlarm();

获取通知错误通知=新通知（R.drawable.icon， “Crazy About Android ...”，System.currentTimeMillis（））;

The constructor Notification(int, CharSequence, long) is deprecated为什么会这样？

Answer 1

您可以使用NotificationBuilder或support.v4库

中提供的support.v13

这里

     private NotificationManager mNotificationManager;
            NotificationCompat.Builder builder;
     mNotificationManager = (NotificationManager)
                    this.getSystemService(Context.NOTIFICATION_SERVICE);

     Intent intent = new Intent(this, ViewMovie_Details.class);         

        PendingIntent alarmIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);     

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle(msg)
        .setStyle(new NotificationCompat.BigTextStyle()
        .bigText(msg))
        .setAutoCancel(true)
        .setContentText("Yuhu New Notification");

        mBuilder.setContentIntent(alarmIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

他们添加了Notification.Builder并希望您使用它。这并不意味着使用旧的方式不会起作用。如果您获得了预期的结果，我可能会忽略这一点，但要了解将来可能有更好的方法来重写您的代码。

来自文档

公共通知（int图标，CharSequence tickerText，长时间）

在API级别1中添加此构造函数在API级别11中已弃用。   请改用Notification.Builder。

我猜它是一个lint警告你正在使用一个不推荐使用的构造函数。

所以使用Notification.Builder。

我正在使用android API级别19，然后也会收到通知错误
