恢复应用

Question

我成功地创建了启动一个服务，它通过转这样表示

public int onStartCommand(Intent intent, int flags, int startId){ 

String notificationText = "working" 
     myNotification = new NotificationCompat.Builder(getApplicationContext()) 
       .setContentTitle("test") 
       .setContentText(notificationText) 
       .setTicker("Notification!") 
       .setWhen(System.currentTimeMillis()) 
       .setDefaults(Notification.DEFAULT_SOUND) 
       .setAutoCancel(true) 
       .setSmallIcon(R.drawable.ic_launcher) 
       .build(); 

//FOLLOWING TECHNIQUE IS DEPRECATED 
/* PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0); 
    myNotification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); */ 

     myNotification.flags |= Notification.FLAG_NO_CLEAR; 
     myNotification.flags = Notification.FLAG_ONGOING_EVENT; 
     notificationManager.notify(1, myNotification); 

     return START_STICKY; 
} 

我知道有与此相关的其他问题，但它们都使用的通知活动setLatestEventInfo它被废弃

这是我从另一个活动调用：

protected void beginBackgroundSer(){ 

     intentService = new Intent(this, Service.class); 
     intentService.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); 
     this.startService(intentService); 

    } 

所以我想要的是简历每当我点击通过非弃用方法的活动。非常感谢您的帮助。

您可以通过以下步骤创建一个通知。

1. 创建通知ID以供将来参考，以通过通知管理器更新通知。 // Notification ID to allow for future updates private static final int MY_NOTIFICATION_ID = 1;

2. 为通知创建文本元素。

   // Notification Text Elements 
   private final CharSequence tickerText = "This is a Really, Really, Super Long Notification Message!"; 
   private final CharSequence contentTitle = "Notification"; 
   private final CharSequence contentText = "You've Been Notified!"; 
   

3. 定义通知动作要素，即当用户点击在通知抽屉什么动作发生的观点？我们使用意图来处理这个问题。

   // Notification Action Elements 
   private Intent mNotificationIntent; 
   private PendingIntent mContentIntent; 
   

4. 您还可以定义此通知的声音和振动。

   // Notification Sound and Vibration on Arrival 
   private Uri soundURI = Uri 
        .parse("android.resource://com.examples.Notification.StatusBarWithCustomView/" 
          + R.raw.alarm_rooster); 
   private long[] mVibratePattern = { 0, 200, 200, 300 }; 
   

5. 使用Notification.Builder类创建通知。在您的onCreate（）

   mNotificationIntent = new Intent(getApplicationContext(), 
        YourActivity.class); 
   mContentIntent = PendingIntent.getActivity(getApplicationContext(), 0, 
        mNotificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK); 
   
   
         // Build the Notification 
   
         Notification.Builder notificationBuilder = new Notification.Builder(
           getApplicationContext()) 
          .setTicker(tickerText) 
          .setSmallIcon(android.R.drawable.stat_sys_warning) 
          .setAutoCancel(true) 
          .setContentIntent(mContentIntent) 
          .setSound(soundURI) 
          .setVibrate(mVibratePattern) 
          .setContent(mContentView); 
   
         // Pass the Notification to the NotificationManager: 
         NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
         mNotificationManager.notify(MY_NOTIFICATION_ID, 
           notificationBuilder.build());

从documentations

公共NotificationCompat.Builder setContentIntent（的PendingIntent意图） - 提供一个的PendingIntent点击通知时发送。如果您没有提供意图，现在可以通过调用RemoteViews.setOnClickPendingIntent（int，PendingIntent）将PendingIntents添加到单击的视图中以启动它们。请务必阅读Notification.contentIntent以了解如何正确使用它。

所以，你可以使用setContentIntent(PendingIntent intent)方法类似

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0); 
myNotification = new NotificationCompat.Builder(getApplicationContext()) 
      .setContentTitle("test") 
      .setContentText(notificationText) 
      .setTicker("Notification!") 
      .setWhen(System.currentTimeMillis()) 
      .setDefaults(Notification.DEFAULT_SOUND) 
      .setAutoCancel(true) 
      .setSmallIcon(R.drawable.ic_launcher) 
      .setContentIntent(contentIntent) //added this new line 
      .build(); 

notificationManager.notify(1, myNotification);
