Android颜色通知图标

Question

我正在开发一个应用程序,我在那里为用户创建通知.我希望图标在状态栏中显示为白色,但在下拉通知菜单中显示时显示为蓝色.以下是Google Store应用程序执行相同操作的示例.

状态栏中的白色通知:

下拉菜单中的彩色通知:

我怎么能复制这个？我需要设置哪些属性？

编辑: 这是我当前的代码 - 我使图像全白,透明背景,所以它在状态栏中看起来很好,但在通知中,图像仍然是相同的白色:

private NotificationCompat.Builder getNotificationBuilder() {
        return new NotificationCompat.Builder(mainActivity)
                .setDeleteIntent(deletedPendingIntent)
                .setContentIntent(startChatPendingIntent)
                .setAutoCancel(true)
                .setSmallIcon(R.drawable.skylight_notification)
                .setColor(ContextCompat.getColor(mainActivity, R.color.colorPrimary))
                .setContentTitle(mainActivity.getString(R.string.notification_title))
                .setContentText(mainActivity.getString(R.string.notification_prompt));
    }

我不完全知道问题是什么,但是将我用于图标的巨大png放入此工具中https://romannurik.github.io/AndroidAssetStudio/icons-notification.html#source.type= image&source.space.trim = 1&source.space.pad = 0&name = ic_skylight_notification ,通过将生成的图标放入我的mipmap文件夹,我能够使该setColor(...)属性正常工作.

对于从控制台发送的firebase nofitications,您只需在清单中添加:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/white_logo" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/custom_color" />

white_logo是您的应用程序白色徽标,custom_color是您希望图标和文本着色的颜色.

这是我为我的应用做的...

private void showNotification(Context context) {
    Log.d(MainActivity.APP_TAG, "Displaying Notification");
    Intent activityIntent = new Intent(context, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
    mBuilder.setSmallIcon(R.drawable.ic_notification);
    mBuilder.setColor(Color.GREEN);
    mBuilder.setContentIntent(pendingIntent);
    mBuilder.setContentTitle("EarthQuakeAlert");
    mBuilder.setContentText("It's been a while you have checked out earthquake data!");
    mBuilder.setDefaults(Notification.DEFAULT_SOUND);
    mBuilder.setAutoCancel(true);
    NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(1, mBuilder.build());
}

构建通知时，可以设置颜色和图标。如果您的图标是纯白色图像，它将在正确的位置为您应用颜色。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    val manager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    val notificationId = 10 // Some unique id.

    // Creating a channel - required for O's notifications.
    val channel = NotificationChannel("my_channel_01",
            "Channel human readable title",
            NotificationManager.IMPORTANCE_DEFAULT)

    manager.createNotificationChannel(channel)

    // Building the notification.
    val builder = Notification.Builder(context, channel.id)
    builder.setContentTitle("Warning!")
    builder.setContentText("This is a bad notification!")
    builder.setSmallIcon(R.drawable.skull)
    builder.setColor(ContextCompat.getColor(context, R.color.colorPrimary))
    builder.setChannelId(channel.id)

    // Posting the notification.
    manager.notify(notificationId, builder.build())
}

Answer 5

我可能会迟到，但以上所有答案都不相关或已弃用。

您可以使用setColor以下方法轻松实现这一点NotificationCompat.Builder

例子：

val builder = NotificationCompat.Builder(this, "whatever_channel_id")
        .setSmallIcon(R.drawable.ic_notification) //set icon for notification
        .setColor(ContextCompat.getColor(this, R.color.pink))
        .setContentTitle("Notification Title")
        .setContentText("Notification Message!")

现在它会将通知显示为粉红色

注意： 如果您使用 firebase，则不会直接看到颜色。您必须将其添加到清单文件中。

<meta-data
    android:name="com.google.firebase.messaging.default_notification_icon"
    android:resource="@drawable/ic_notification" />

<meta-data
    android:name="com.google.firebase.messaging.default_notification_color"
    android:resource="@color/pink" />
