Picasso的封装(二)

public class PicassoUtils {    //默认加载图片    public static void loadImaheView(Context mContext, String url, ImageView imageView) {        Picasso.with(mContext).load(url).into(imageView);    }    //默认加载图片(指定大小)    public static void loadImageViewSize(Context mContext, String url, int width, int height, ImageView imageView) {        Picasso.with(mContext).load(url).config(Bitmap.Config.RGB_565).resize(width, height).centerCrop().into(imageView);    }    //加载图片有默认图片    public static void loadImageViewHolder(Context mContext, String url, int loadImg,                                           int errorImg, ImageView imageView) {        Picasso.with(mContext).load(url).placeholder(loadImg).error(errorImg)                .into(imageView);    }    //裁剪图片    public static void loadImageViewCrop(Context mContext, String url,ImageView imageView){        Picasso.with(mContext).load(url).transform(new CropSquareTransformation()).into(imageView);    }    //按比例裁剪 矩形    public static class CropSquareTransformation implements Transformation {        @Override        public Bitmap transform(Bitmap source) {            int size = Math.min(source.getWidth(), source.getHeight());            int x = (source.getWidth() - size) / 2;            int y = (source.getHeight() - size) / 2;            Bitmap result = Bitmap.createBitmap(source, x, y, size, size);            if (result != source) {                //回收                source.recycle();            }            return result;        }        @Override public String key() {            return "lgl";        }    }}
