Question

我成功创建了一个启动服务的活动，而该服务又显示了这样的通知

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; 
}

我知道还有其他与此相关的问题但他们都使用了setLatestEventInfo已被弃用

这就是我从另一项活动中所说的：

protected void beginBackgroundSer(){

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

    }

因此，无论何时通过非弃用方法点击通知，我都希望恢复活动。非常感谢你的帮助。

Answer 1

来自documentations

public NotificationCompat.Builder setContentIntent（PendingIntent intent） - 提供PendingIntent以在单击通知时发送。如果您不提供意图，现在可以通过调用RemoteViews.setOnClickPendingIntent（int，PendingIntent）将PendingIntents添加到要启动的单个视图中。请务必阅读Notification.contentIntent以了解如何正确使用它。

因此您可以使用{/ 1}}方法，例如

setContentIntent(PendingIntent intent)

您可以使用以下步骤创建通知。

为将来的参考创建通知ID，以便通知管理器更新通知。 // Notification ID to allow for future updates private static final int MY_NOTIFICATION_ID = 1;

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!";

定义通知操作元素，即当用户点击通知抽屉中的视图时会发生什么操作？我们使用意图来处理这个问题。
```
// Notification Action Elements
private Intent mNotificationIntent;
private PendingIntent mContentIntent;
```

您还可以为此通知定义声音和振动。

// 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 };

使用Notification.Builder类创建通知。在你的onCreate（）

中执行此操作

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());

通过单击服务的通知来恢复应用程序
