毕加索没有加载特定的图片网址答案

【问题标题】：Picasso not loading a particular image url毕加索没有加载特定的图片网址

【问题描述】：

我正在尝试使用 picasso 加载此 http://assets.myntassets.com/v1/images/style/properties/Jockey-Men-Black-Innerwear-Vest-9926-0105_435418e1b17c4d0c5583dd33ba24193d_images.jpg 网址。检查日志时显示errored。但是当我通过以下方式尝试相同的网址时：

InputStream is = (InputStream) new URL(url).getContent();
Bitmap d = BitmapFactory.decodeStream(is);

图片正在加载。这很奇怪。不知道为什么会这样。

这里是日志：

D/Picasso (27123): Main        created      [R9] Request{http://assets.myntassets.com/v1/images/style/properties/Jockey-Men-Black-Innerwear-Vest-9926-0105_435418e1b17c4d0c5583dd33ba24193d_images.jpg resize(720,1184) centerInside}

毕加索的代码：

Picasso.with(context)
                    .load(url)
                    .resize(height,width)
                    .centerInside()
                    .into(imgView);

对于这种特殊情况，height 和 width 分别是 720 和 1184。

【问题讨论】：

请显示一些代码。
@FaroukTouzi：添加代码。
您可以尝试加载到Target，而不是直接加载到ImageView。这样您就可以轻松调试正在发生的事情。 square.github.io/picasso/javadoc/com/squareup/picasso/…
尝试从 url 中删除 - 只需使用 _
还要检查错误尝试将监听器绑定到毕加索

【解决方案2】：

按照此示例，您将获得适合 MAX_WIDTH 和 MAX_HEIGHT 范围内的图像（保持纵横比）

private static final int MAX_WIDTH = 1024;
private static final int MAX_HEIGHT = 768;

int size = (int) Math.ceil(Math.sqrt(MAX_WIDTH * MAX_HEIGHT));

// Loads given image
Picasso.with(imageView.getContext())
   .load(imagePath)
   .transform(new BitmapTransform(MAX_WIDTH, MAX_HEIGHT))
   .skipMemoryCache()
   .resize(size, size)
   .centerInside()
   .into(imageView);

这是我自定义的 BitmapTransform 类：

import android.graphics.Bitmap;
import com.squareup.picasso.Transformation;

/** * 转换加载的图像以避免 OutOfMemoryException */

public class BitmapTransform implements Transformation {

    int maxWidth;
    int maxHeight;

    public BitmapTransform(int maxWidth, int maxHeight) {
        this.maxWidth = maxWidth;
        this.maxHeight = maxHeight;
    }

 @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;
}

};
