我正在尝试创建一个具有高优先级的通知(一个聊天应用程序),但我的客户要求它不会有“抬头”视图。
我尝试创建一个空布局以将 aRemoteViews
设置为Notification.headsUpContentView
但仍然没有。
这是我尝试过的:
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
