ViewEventActivity.class 无法识别

Question

我的代码源是https://developer.android.com/training/wearables/notifications/creating.html

在此示例代码中，第二部分 NotificationCompat 工作得很好..但我在 MainActivity.class 中有此代码，它给出了一个错误 "ViewEventActivity.class is not recognised"

现在这是什么ViewEventActivity.class，在哪里添加它以及如何实现它

代码片段::

   int notificationId = 001;
    // Build intent for notification content
    Intent viewIntent = new Intent(this, ViewEventActivity.class);
    viewIntent.putExtra(EXTRA_EVENT_ID, eventId);
    PendingIntent viewPendingIntent =
            PendingIntent.getActivity(this, 0, viewIntent, 0);

    NotificationCompat.Builder notificationBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_event)
            .setContentTitle(eventTitle)
            .setContentText(eventLocation)
            .setContentIntent(viewPendingIntent);

    // Get an instance of the NotificationManager service
    NotificationManagerCompat notificationManager =
            NotificationManagerCompat.from(this);

    // Build the notification and issues it with notification manager.
    notificationManager.notify(notificationId, notificationBuilder.build());

任何建议都会有很大帮助

Answer 1

替换

Intent viewIntent = new Intent(this, ViewEventActivity.class);

与

Intent viewIntent = new Intent();

这就是在单击 Notification.Its 时启动 Activity 的示例代码，与 Android 无关 API.if 您希望在单击时启动任何 Activity然后用 ViewEventActivity.class 替换 Activity 否则忽略它

Answer 2

"ViewEventActivity.class is not recognized"

ViewEventActivity 与任何 API 的 class 无关。所以你需要创建你自己的class，你想在通知点击时用任何名字打开它，而不是像其他class一样ViewEventActivity。

因此，通过扩展 Activity

在您的应用程序中创建 ViewEventActivity class

同时在 AndroidManifest.xml 中添加 ViewEventActivity class 作为 Activity:

 <activity
     android:name=".ViewEventActivity"
      ...  
  />
