使用picasso设置与imageview背景相同的图像

implementation 'com.squareup.picasso:picasso:2.71828'

Picasso.get()
    .load("图片URL")
    .into(new Target() {
        @Override
        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
            imageView.setBackground(new BitmapDrawable(getResources(), bitmap));
        }

        @Override
        public void onBitmapFailed(Exception e, Drawable errorDrawable) {
            // 加载失败时的处理
        }

        @Override
        public void onPrepareLoad(Drawable placeHolderDrawable) {
            // 图像加载前的准备工作
        }
    });

Picasso.get()
    .load("图片URL")
    .placeholder(R.drawable.placeholder_image)
    .error(R.drawable.error_image)
    .into(new Target() {
        // ...
    });
