我要的图像视图设置URL图像的问题。我尝试以下方法

i have a problem in set url image to image view. i tried below methods

方法1：

Bitmap bimage=  getBitmapFromURL(bannerpath);
image.setImageBitmap(bimage);

 public static Bitmap getBitmapFromURL(String src) {
        try {
            Log.e("src",src);
            URL url = new URL(src);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap myBitmap = BitmapFactory.decodeStream(input);
            Log.e("Bitmap","returned");
            return myBitmap;
        } catch (IOException e) {
            e.printStackTrace();
            Log.e("Exception",e.getMessage());
            return null;
        }
    }

方法2：

    Drawable drawable = LoadImageFromWebOperations(bannerpath);
    image.setImageDrawable(drawable);

     private Drawable LoadImageFromWebOperations(String url)
    {
         try
         {
             InputStream is = (InputStream) new URL(url).getContent();
             Drawable d = Drawable.createFromStream(is, "src name");
             return d;
         }catch (Exception e) {
             System.out.println("Exc="+e);
             return null;
         }
     }

我尝试上述两种方法，但都没有工作。两者都显示DEBUG / Skia的（266）：---德codeR->德code返回false。我使用的是有效的演示图像的URL路径。但是这条路是行不通的。所以请告诉我什么是错的，我会做什么

i tried above two methods but are not working . both are showing DEBUG/skia(266): --- decoder->decode returned false . i used demo url image paths that is working. but this path is not working .so please tell me what is the wrong and what i will do

感谢你在前进。

最好的问候。

只是测试你的方法1在我的应用程序，它工作得很好。

Just Tested your "Method 1" in my app and it works just fine.
