Picasso's Target and centerCrop() and fit()

Question

I have an image on my server and I want to display it using Picasso on my Android client. I want to add a default image when the image is loading on Picasso so I am using Target as follows:

Picasso.with(UserActivity.this).load(imageUri.toString()).transform(new RoundedTransformation(500, 1)).into(
new Target() {
    @Override
    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
        userPic.setImageBitmap(bitmap);
    }

    @Override
    public void onBitmapFailed(Drawable drawable) {
        userPic.setImageBitmap(defaultDrawable);
    }

    @Override
    public void onPrepareLoad(Drawable drawable) {
        userPic.setImageBitmap(defaultDrawable);
    }
});

I want to centerCrop() and fit() this image but it gives me an error and it tells me that I cant use them with Target. Is there anyway to use these features on Picasso? Why don't they allow these two functions with Target?

Answer 1

You don't need to use Target to accomplish your goal.

Side note, I am not certain that you can actually use both fit() and centerCrop() together.

See this example:

Picasso.with(context)
    .load(url) // Equivalent of what ends up in onBitmapLoaded
    .placeholder(R.drawable.user_placeholder) // Equivalent of what ends up in onPrepareLoad
    .error(R.drawable.user_placeholder_error) // Equivalent of what ends up in onBitmapFailed
    .centerCrop()
    .fit()
    .into(imageView);
