没有 "heads up" 的通知

Question

我正在尝试创建一个具有高优先级的通知（聊天应用程序），但我的客户要求不会有 "heads up" 视图。

我已经尝试为 RemoteViews 创建一个空布局以设置为 Notification.headsUpContentView 但仍然没有。

这是我试过的方法：

    Intent target = new Intent(this, PushConsumedBroadcastReceiver.class);
    target.putExtra(PushConsumedBroadcastReceiver.PUSH_TYPE, PushConsumedBroadcastReceiver.PUSH_TYPE_REMINDER);

    PendingIntent pending = PendingIntent.getBroadcast(this, Constants.REQUEST_CODE_BASE, target, PendingIntent.FLAG_UPDATE_CURRENT);
    Notification notification = new Notification.Builder(this).setContentIntent(pending)
    .setContentTitle(item.getNotificationText())
    .setStyle(new BigTextStyle().bigText(item.getNotificationText()).setSummaryText("thepoosh looks good"))
    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
    .setSmallIcon(R.drawable.g_icon_white)
    .setPriority(Notification.PRIORITY_MAX)
    .setTicker(item.getNotificationText())
    .build();

    if(VERSION.SDK_INT >= VERSION_CODES.LOLLIPOP) {
        notification.headsUpContentView = new RemoteViews(getPackageName(), R.layout.empty_heads_up);
    }
    notification.sound = null;
    notification.ledARGB = 0;
    notification.vibrate = new long[0];

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(CODE_ONE_DAY_REMINDER, notification);

empty_heads_up.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" />

Answer 1

显示提醒通知是 the definition of a high-priority notification 的一部分：

If a notification's priority is flagged as High, Max, or full-screen, it gets a heads-up notification.

如果您不想要提醒通知，那么您就不需要高优先级通知。

请注意，您的用户可以选择禁用提醒通知或自行降低通知的优先级，但这是仅供用户使用的选项。

Answer 2

如果您坚持使用PRIORITY_MAX，您可以使用以下以API 21:

开头的代码禁用Heads-Up通知

notification.headsUpContentView = new RemoteViews(Parcel.obtain());

没有 "heads up" 的通知

Notification without "heads up"
