Photoview Fit Screen Height Maintain Aspect Ratio

I cant scaletype for my PhotoView that lets me pan side to side on an image while being full-screen, without cropping the sides using Photo.ScaleType.CENTER_CROP. How would I go ab

Solution 1:

you can use a this ImageViewZoom.

if you don't want to use lib see the codes and try to scale canvas

Solution 2:

I fixed it by using a PhotoViewAttacher like this:

ImageViewimageView= (ImageView) findViewById(R.id.preview);
PhotoViewAttacherphotoViewAttacher=newPhotoViewAttacher(imageView);
photoViewAttacher.setScaleType(ImageView.ScaleType.CENTER_CROP)

and then using an ImageView (id.preview) with the ScaleType in the XML set as Matrix. (otherwise it wont work)
