Resize a bitmap respecting the aspect radio. I use a custom transformations with Picasso library. This transformation calculate the new dimension of the bitmap scaling it to fit a specific width or height that we pass as a parameter (usually the biggest size of the imageView where we wanna set the bitmap).
public class ScaleToFitWidthHeightTransform implements Transformation {
private int mSize;
private boolean isHeightScale;
public ScaleToFitWidthHeightTransform(int size, boolean isHeightScale){
mSize =size;
this.isHeightScale = isHeightScale;
}
