Question

请您帮我解决下面的问题？

我创建了一个简单的应用程序，显示传入短信的通知。在该通知上，我添加了一个按钮，通过通知删除SMS。

由于我有三星Gear S2，智能手表上会显示删除按钮，我可以使用我的Gear S2删除短信。

主要问题是当我使用Gear S2删除短信时，屏幕会被唤醒。当我使用Gmail进行测试时，同样的方案只是删除电子邮件并关闭屏幕。

那么，请你帮我解开屏幕开启的原因吗？

在这里，我是如何创建通知的（收到短信后）。

// Intent used to delete the SMS
Intent deleteIntent = new Intent(context, MessagingService.class);
deleteIntent.putExtra("notiID", id);
deleteIntent.putExtra("address", address);
deleteIntent.putExtra("date", date);
deleteIntent.putExtra("body", body);
PendingIntent deletePendingIntent = PendingIntent.getService(
        context,
        id,
        deleteIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);

// Intent used to start the app
Intent clickIntent = new Intent(context, MainActivity.class);
PendingIntent clickPendingIntent = PendingIntent.getActivity(
        context,
        id + 1,
        clickIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);

// Notification
NotificationCompat.Builder notiBuilder = new NotificationCompat.Builder(context);
notiBuilder.setSmallIcon(R.drawable.ic_message_white_32dp)
        .setContentTitle(address)
        .setContentText(body)
        .setContentIntent(clickPendingIntent)
        .addAction(R.drawable.ic_delete_white_32dp, context.getString(R.string.delete), deletePendingIntent)
        .setLights(Color.BLUE, 3000, 3000);

Notification mNotificationBar = notiBuilder.build();

NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Service.NOTIFICATION_SERVICE);
mNotificationManager.notify(id, mNotificationBar);

我测试的内容：

目前，我正在移动＆＃34;短信删除＆＃34;代码到Service。这就是我使用的原因：

Intent deleteIntent = new Intent(context, MessagingService.class);
PendingIntent deletePendingIntent = PendingIntent.getService(....);

但我也尝试使用BroadcastReceiver删除短信（结果相同）：

Intent deleteIntent = new Intent(context, SmsReceiver.class);
deleteIntent.setAction("com.test.simplesms.DELETE_MESSAGE");
PendingIntent deletePendingIntent = PendingIntent.getBroadcast(....);

所以，我不确定为什么deletePendingIntent配置的操作会打开屏幕。

我认为您的SmsReceiver类来自WakefulBroadcastReceiver

最终，我可以修复错误，我在这里分享以供将来参考。

经过调试和研究后，我发现我应该通过WearableExtender扩展可穿戴设备的通知。

这样，addAction()将动作添加到通知栏，extend()添加WearableExtender，配置智能手表可以执行的操作（这样，您可以配置不同的通知栏和智能手表的东西）

// Intent used to delete the SMS
Intent deleteIntent = new Intent(context, SmsReceiver.class);
deleteIntent.putExtra("notiID", id);
deleteIntent.putExtra("address", address);
deleteIntent.putExtra("date", date);
deleteIntent.putExtra("body", body);
PendingIntent deletePendingIntent = PendingIntent.getBroadcast(
        context,
        id,
        deleteIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);

// Intent used to start the app
Intent clickIntent = new Intent(context, MainActivity.class);
PendingIntent clickPendingIntent = PendingIntent.getActivity(
        context,
        id + 1,
        clickIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);

// ADD THIS
// Add a wearable extender.. an wearable action
NotificationCompat.WearableExtender wearableExtender = new NotificationCompat.WearableExtender();
wearableExtender.addAction(new NotificationCompat.Action(R.drawable.ic_delete_white_32dp, context.getString(R.string.delete), deletePendingIntent));


// Notification
NotificationCompat.Builder notiBuilder = new NotificationCompat.Builder(context);
notiBuilder.setSmallIcon(R.drawable.ic_message_white_32dp)
        .setContentTitle(address)
        .setContentText(body)
        .setContentIntent(clickPendingIntent)
        .extend(wearableExtender)  // ----> ADD THE WEARABLE HERE
        .addAction(R.drawable.ic_delete_white_32dp, context.getString(R.string.delete), deletePendingIntent)
        .setLights(Color.BLUE, 3000, 3000);

Notification mNotificationBar = notiBuilder.build();

NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Service.NOTIFICATION_SERVICE);
mNotificationManager.notify(id, mNotificationBar);

在通知中处理自定义操作时，防止打开屏幕的设备
