Hello Picasso + Android用户,

我使用了以下版本的 Picasso ,并使用了以下转化代码段:

  

compile' com.squareup.picasso:picasso:2.3.2'

并为Image Transformation

创建了转换
public class ImageTransformation implements Transformation {

    int maxWidth;
    int maxHeight;

    public ImageTransformation(ImageView imageView) {
        this.maxWidth = imageView.getWidth();
        this.maxHeight = imageView.getHeight();
    }

    @Override
    public Bitmap transform(Bitmap source) {
        int targetWidth, targetHeight;
        double aspectRatio;

        if (source.getWidth() > source.getHeight()) {
            targetWidth = maxWidth;
            aspectRatio = (double) source.getHeight() / (double) source.getWidth();
            targetHeight = (int) (targetWidth * aspectRatio);
        } else {
            targetHeight = maxHeight;
            aspectRatio = (double) source.getWidth() / (double) source.getHeight();
            targetWidth = (int) (targetHeight * aspectRatio);
        }

        Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
        if (result != source) {
            source.recycle();
        }
        return result;
    }

    @Override
    public String key() {
        return maxWidth + "x" + maxHeight;
    }
}

和使用类似:

Picasso.with(mContext).load(photo.getLink())
                .error(R.drawable.ic_place_holder_circle)
                .placeholder(R.drawable.ic_place_holder_circle)
                .transform(new ImageTransformation(holder.albumPhotoDetailSubMainImage))
                .into(holder.albumPhotoDetailSubMainImage);

现在我想使用以下新版本中提供的.priority()

  

compile' com.squareup.picasso:picasso:2.5.2'

但它给了我转换的错误,如:

java.lang.IllegalArgumentException: width and height must be > 0
        at android.graphics.Bitmap.createBitmap(Bitmap.java:815)
        at android.graphics.Bitmap.createBitmap(Bitmap.java:794)
        at android.graphics.Bitmap.createBitmap(Bitmap.java:725)
        at com.squareup.picasso.BitmapHunter.transformResult(BitmapHunter.java:558)
        at com.squareup.picasso.BitmapHunter.hunt(BitmapHunter.java:232)
        at com.squareup.picasso.BitmapHunter.run(BitmapHunter.java:159)
        at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:422)

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587)
        at java.lang.Thread.run(Thread.java:818)
        at com.squareup.picasso.Utils$PicassoThread.run(Utils.java:411)

我仅在full code的新版本中收到此错误。

有什么解决方案可以解决吗?

我们将不胜感激。

我认为您应该使用以下内容:

        public ImageTransformation(ImageView imageView) {
            this.maxWidth = imageView.getLayoutParams().width; //imageView.getWidth();
            this.maxHeight = imageView.getLayoutParams().height; //imageView.getHeight();
            // check
            if (this.maxWidth <= 0) {
                this.maxWidth = ...
            }
            if (this.maxHeight <= 0) {
                this.maxHeight = ...
            }
        }

关于异常,实际上,ver 2.3.2也得到了它,但是,它有不同的处理异常的方法。您可以看到以下2个屏幕截图:
