无法从final继承

Question

I have a java image analysis program and am trying to get it to run on android. It starts like this (working on standard java):

import java.awt.image.BufferedImage;
public MaskImage(BufferedImage srcImage) {
    super(srcImage.getWidth(), srcImage.getHeight(), srcImage.getType());
    this.srcImage = srcImage;
    this.height = srcImage.getHeight();
    this.width = srcImage.getWidth();
}

When I try to get it working on android studio however I change bufferedimage to Bitmap, but still run into a couple of problems:

1. I cannot extend Bitmap in the same way I could BufferedImage

2. super(srcImage.getWidth(), srcImage.getHeight(), srcImage.getType());

this line runs into multiple issues, Says:

expected Parameters; actual: Arguments;

Thanks For any Help!

Answer 1

As you already know, Bitmap is final . By the very definition of final classes in Java, this means you cannot subclass it.

You will need to find an alternate strategy for accomplishing whatever you are trying to accomplish. Perhaps creating a class that wraps a Bitmap is one solution.
