ImageView fills parent's width OR height, but maintains aspect ratio

Question

I have a square image (though this problem also applies to rectangular images). I want to display the image as large as possible, stretching them if necessary, to fill thei

Answer 1

Set android:layout_height="wrap_content" in imageview. To create an image with width equals screen width, and height proportionally set according to aspect ratio, do the following. Here I mention how to load image to imageview from url.

Glide.with(context).load(url).asBitmap().into(new SimpleTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {

                        // creating the image that maintain aspect ratio with width of image is set to screenwidth.
                        int width = imageView.getMeasuredWidth();
                        int diw = resource.getWidth();
                        if (diw > 0) {
                            int height = 0;
                            height = width * resource.getHeight() / diw;
                            resource = Bitmap.createScaledBitmap(resource, width, height, false);
                        }
                                              imageView.setImageBitmap(resource);
                    }
                });

Hope this helps.
