通知通道 - 设置后是否可以更改 LightColor?

Dem*_*otz 2 java notifications android channel led

我正在尝试setLightColor使用从 JavaScript 界面返回的颜色进行更改。不幸的是,NotificationCompat.Builder(context, CHANNEL_ID).setLights对 API >= 26 绝对没有影响,所以我不能使用Intent.putExtra或任何类似的东西。

设置好之后还能修改吗?我希望它是动态的。

编辑似乎对我想要的东西有一些误解。我不想碰Broadcast Reciever. 它工作得很好。我想更改通知渠道。它没有更新setLightColor(Color.___)

protected void onCreate

String jobColor = someColor; // Will be filled in by other code - different colour every time
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    CharSequence name = "Channel_Name";
    String description = "Channel_Description";
    int importance = NotificationManager.IMPORTANCE_HIGH;
    NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
    channel.setDescription(description);
    channel.enableLights(true);
    channel.setLightColor(Color.parseColor(jobColor)); // Dynamically set from above
    channel.enableVibration(true);
    NotificationManager notificationManager = getSystemService(NotificationManager.class);
    notificationManager.createNotificationChannel(channel);
}

我相信我的 BroadcastReciever - setLight 不适用于 API 26 或更高版本

public class AlarmReceiver extends BroadcastReceiver {
private final String CHANNEL_ID = "some_channel";
@Override
public void onReceive(Context context, Intent intent) {
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0 , new Intent(context, MainPage.class), 0);
    String jobColor = intent.getStringExtra("jobColor");

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .setSmallIcon(R.drawable.ic_stat_name)
            .setContentTitle("Upcoming Shift!")
            .setContentText("Shift at " + intent.getStringExtra("jobName") + " on " + intent.getStringExtra("jobDate") + " at " + intent.getStringExtra("jobTime"))
            .setStyle(new NotificationCompat.BigTextStyle().bigText("You have a shift at " + intent.getStringExtra("jobName") + " on " + intent.getStringExtra("jobDate") + " at " + intent.getStringExtra("jobTime")))
            .setLights(Color.parseColor(jobColor), 10000, 1000)
            .setContentIntent(pendingIntent)
            .setAutoCancel(true);
    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
    notificationManager.notify(12345, mBuilder.build());
}
}

您不能在不删除频道的情况下以编程方式更改频道颜色通知、重要性等。

因为用户可能已经手动更改了灯光颜色。

以编程方式实现此目的以获取频道并使用新 ID 创建新频道。删除旧频道。如果使用以前的 ID 创建频道,您的更改将不会反映出来

供参考 检查 WhatsApp 应用程序尝试从应用程序更改铃声并在左下角的频道中查看 x 频道已删除消息
