Question

根据文档，我在应用程序中进行了更改，以便使用context.startForegroundService(Intent)在后台启动服务，然后像以前一样在服务中调用startForeground。

NotificationCompat.Builder notification = new 
NotificationCompat.Builder(getApplicationContext())
            .setSmallIcon(R.mipmap.icon)
            .setContentText("Content")
            .setOngoing(true)
            .setContentInfo("Info")
            .setContentTitle("Title");
startForeground(1, notification.build());

这会在Android N设备上正确显示通知，但在Android O设备上，它不会显示通知，只显示新的＆＃34;正在后台运行...点击了解有关电池和数据使用情况的详细信息＆＃34;

是否缺少某些内容才能在Android O上正确显示通知？

Answer 1

上面的答案对我不起作用。您必须创建频道才能工作，然后传递频道ID。

new NotificationCompat.Builder(this, channelId)

然后使用相同的cannelId

创建一个notfication

add_shortcode('bookmaker', 'bookmaker_shortcode_query');

function bookmaker_shortcode_query($atts, $content){
  $args = shortcode_atts(array( // a few default values
   'posts_per_page' => '1',
   'post_type' => 'your_custom_post_type',
   'p' => '1',
   'caller_get_posts' => 1)
   , $atts);


  global $post;

  $posts = new WP_Query($args);
  $output = '';
    if ($posts->have_posts())
        while ($posts->have_posts()):
            $posts->the_post();
            $out = '        <div class="bookmaker">
