我正在尝试用JavaScript接口返回的颜色更改setLightColor
。不幸的是,NotificationCompat.Builder(context, CHANNEL_ID).setLights
在API> = 26上绝对没有影响力,所以我不能使用Intent.putExtra
或类似的东西。
设置完成后是否还可以更改?我希望它是动态的。
编辑对于我想要的东西似乎有些误解。我不想触摸Broadcast Reciever
。它工作正常。我想更改通知频道。它不是在更新setLightColor(Color.___)
。
在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);
}
我的BroadcastReciever-我相信 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());
}
}

从createNotificationChannel()描述:
这还可以用于还原已删除的频道并更新现有频道的频道 *名称,说明,组和/或重要性。
因此您可以尝试以下操作:
NotificationManager notificationManager = getSystemService(NotificationManager.class);
//find created channel
NotificationChannel channel = notificationManager.getNotificationChannel("id");
if (channel != null){
//set new color
channel.setLightColor(0);
//update channel
notificationManager.createNotificationChannel(channel);
}

在不删除频道的情况下,无法通过编程方式更改频道颜色通知,重要性等。
因为用户可能手动更改了灯光颜色。
要以编程方式实现此目的,以获取频道并创建具有新ID的新频道。删除旧频道。 如果使用先前的ID创建频道,您的更改将不会反映
