推荐答案

你可能是说 Notification.Builder.setLargeIcon(Bitmap) 吧?:)

You probably mean Notification.Builder.setLargeIcon(Bitmap), right? :)

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.large_icon);
notBuilder.setLargeIcon(largeIcon);

这是将资源图像转换为 Android Bitmaps 的好方法.

This is a great method of converting resource images into Android Bitmaps.
