java.lang.IllegalArgumentException:毕加索中的路径不能为空 [英] java.lang.IllegalArgumentException: Path must not be empty in Picasso

问题描述

我正在使用Picasso从mysql DB加载图像到自定义listview中.当直接传递URL时，图像正在加载，但是当我将URL分配给字符串并传递它时，它将引发异常，表示Path不能为空.

I am loading image from mysql DB using Picasso into custom listview. The image is loading when the URL is passed directly but when i assign the URL to string and pass it then it throws exception saying Path must not be empty.

String imageStringUrl = md.Image;

图像字符串包含 http://example.com/image.jpg

我正在通过毕加索，如下所示.

I am passing in Picasso like below.

Picasso.get()
.load(imageStringUrl)
.into(iview);                                                           

当我这样传递时，我得到了java.lang.IllegalArgumentException:路径不能为空.我已经尝试过如下所示的上述步骤，但是图像未加载.

When I pass like this I am getting java.lang.IllegalArgumentException: Path must not be empty. I have tried the above step like below but the image is not loading.

Picasso.get()
.load(new File(imageStringUrl))
.into(iview);

以上声明有什么问题?

推荐答案

我遇到了类似的问题.只需检查您的URL字符串是否为空即可.如果为空，则提供默认图像或从URL加载.希望这会有所帮助.

I had a similar problem. Just check if your URL string is empty or not. if it is empty give the default image or load from URL. Hope this helps.

if (image.isEmpty()) {
   iview.setImageResource(R.drawable.placeholder);
} else{
    Picasso.get().load(image).into(iview);
  }
