Resize image to full width and fixed height with Picasso

I have a vertical LinearLayout where one of the items is an ImageView loaded using Picasso. I need to rise the image's width to the full device width, and to display the center part of the image cropped by a fixed height (150dp). I currently have the following code:

Picasso.with(getActivity()) 
    .load(imageUrl) 
    .placeholder(R.drawable.placeholder) 
    .error(R.drawable.error) 
    .resize(screenWidth, imageHeight)
    .centerInside() 
    .into(imageView);

Which values should I put into screenWidth and imageHeight (=150dp)?

You are looking for:

.fit().centerCrop()

What these mean:

• fit - wait until the ImageView has been measured and resize the image to exactly match its size.
• centerCrop - scale the image honoring the aspect ratio until it fills the size. Crop either the top and bottom or left and right so it matches the size exactly.

In some case the fit() is useless. Before you must wait for the width and height measurement to end. So you can use globallayoutlistener. for example;

imageView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                Picasso.with(getActivity())
                        .load(imageUrl)
                        .placeholder(R.drawable.placeholder)
                        .error(R.drawable.error)
                        .resize(screenWidth, imageHeight)
                        .fit
                        .centerInside()
                        .into(imageView);
                imageView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            }
        });
