Question

我正在使用此代码发送本地通知

mNotificationManager = (NotificationManager)
                getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                i, PendingIntent.FLAG_ONE_SHOT);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
                        .setContentTitle(title)
                        .setDefaults(Notification.DEFAULT_SOUND)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(msg))
                        .setContentText(msg);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify((int)value, mBuilder.build());

但是，如果通过滑动锁定手机屏幕，它们会显示在状态栏上。我想在屏幕上显示推送通知，如whatsapp，facebook，sms消息等。

我怎样才能做到这一点？

你可以这样做：

添加以下行：

setPriority(Notification.PRIORITY_MAX)

完整代码：

mNotificationManager = (NotificationManager)
                getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                i, PendingIntent.FLAG_ONE_SHOT);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
                        .setContentTitle(title)
                        .setDefaults(Notification.DEFAULT_SOUND)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(msg))
                        .setContentText(msg)
                        .setPriority(Notification.PRIORITY_MAX);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify((int)value, mBuilder.build());

希望这会对你有所帮助。
