以编程方式获取 ImageView src

Question

如何以编程方式获取 ImageView src 并将其设置在另一个 ImageView

Drawable drawable = imageViewA....?
imageViewB.setImageDrawable(drawable);

Answer 1

你可以这样做：

Drawable drawable = imageViewA.getDrawable();
if(drawable != null){
    imageViewB.setImageDrawable(drawable);
}

Answer 2

你可以使用setImageResource(int)

imageView.setImageResource(R.drawable.bg_image);

Answer 3

而不是 get drawable 你做...

Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();

并设置为新图片

newImageView.setImageBitmap(bitmap);
