【问题描述】:
我正在尝试使用从 JavaScript 接口返回的颜色更改 setLightColor。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 或类似的东西。
是否可以在设置后更改它?我希望它是动态的。
编辑似乎对我想要的东西有些误解。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.___)。
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 - 我认为 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());
}
}

每次当您想更新当前内容时更新通知。
