当背景颜色为白色时，Android 通知图标颜色不会改变 [英] Android notification icon color is not changed when background color is white

问题描述

我升级了 android 6.0 并且我的应用程序有问题.

I upgraded android 6.0 and my app have problem.

当状态栏背景颜色不是白色时，通知图标是好的.(通知图标png只有白色和alpha)

when the status bar background color is not white, notification icon is good. (notification icon png has white and alpha only)

但如果某些应用将背景颜色更改为白色，我的通知图标不会反转为黑色.

but if some apps change background color to white, my notification icon isn't inverted to black.

当其他应用程序将状态栏背景颜色设置为白色时，如何将白色通知图标反转为黑色?(我不是说如何使用彩色图标.)

How can I invert white notification icon to black when status bar background color set white by other app? (I'm not saying how can I use color icon.)

下图显示了一个问题.

正常状态

当把背景颜色改成白色时，我的图标不会变成只有黑色

• 通知构建代码

• Notification build code

  Notification.Builder mBuilder =
          new Notification.Builder(context)
                  .setSmallIcon(R.drawable.ic_notifications_none)
                  .setPriority(priority2)
                  .setOngoing(true);

  mBuilder.setContent(generateMessageView(message));

  Intent notificationIntent = new Intent(context, MainActivity.class);
  notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP 
                            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

  PendingIntent intent = PendingIntent.getActivity(context, 0,
          notificationIntent, 0);
  NotificationManager mNotificationManager =
          (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
  mBuilder.setContentIntent(intent);
  mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

我将通知图标添加到 drawable 目录中，而不是 drawable-*dpi.现在它可以工作了.

I added notification icons to drawable directory not drawable-*dpi. Now it's working.
