记:Android 8.0通知栏显示问题

在Android最新的版本(8.0)中,通知栏的显示已经不像之前那么简单,必须给Notification添加channel,这是8.0的新特性,如果不加这个channel,会导致通知栏无法显示。代码如下:

NotificationCompat.Builder builder = null;

if(android.os.Builde.VERSION.SDK_INT >= Builder.VERSION_CODES.O) {

NotificationChannel channel = new NotificationChannel(PRIMARY_CHANNEL, 'Primary channel', NotificationManager.IMPORTANCE_DEFAULT);

channel.setLightColor(Color.GREEN);

channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);

notificationManager.createNotificationChannel(channel);

builder = new NotificationCompat.Builder(context, PRIMARY_CHANNEL);

}
