我怎样才能获取从URL一个大的图像？ [英] How can I fetch a large image from a url?

问题描述

我用code以下，从一个网址抓取图像，但它不工作的高画质图像。

我缺少的东西时，取该类型的形象？

  imgView =（ImageView的）findViewById（R.id.ImageView01）;
  imgView.setImageBitmap（loadBitmap（http://www.360technosoft.com/mx4.jpg））;

  //imgView.setImageBitmap(loadBitmap("http://sugardaddydiaries.com/wp-content/uploads/2010/12/how_do_i_get_sugar_daddy.jpg"));
     //setImageDrawable("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg");
  //绘制对象绘制= LoadImageFromWebOperations（http://www.androidpeople.com/wp-content/uploads/2010/03/android.png）;
  //imgView.setImageDrawable(drawable）;

 /* 尝试 {
     ImageView的I =（ImageView的）findViewById（R.id.ImageView01）;
     点阵位图= BitmapFactory.de codeStream（（InputStream的）新的URL（http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg）.getContent（）） ;
     i.setImageBitmap（位）;
   }赶上（MalformedURLException异常E）{
     的System.out.println（你好）;
   }赶上（IOException异常E）{
    的System.out.println（你好）;
   } * /
    }


 受保护的可绘制ImageOperations（上下文的背景下，串串，
   字符串字符串2）{
  // TODO自动生成方法存根
  尝试 {
   InputStream的是=（的InputStream）this.fetch（串）;
   绘制对象D = Drawable.createFromStream（是，SRC）;
   返回D组;
  }赶上（MalformedURLException异常E）{
   e.printStackTrace（）;
   返回null;
  }赶上（IOException异常E）{
   e.printStackTrace（）;
   返回null;
  }

 }
 

解决方案

看这很好的例子加载图像的服务器。  <一href="http://blog.sptechnolab.com/2011/03/04/android/android-load-image-from-url/.">blog.sptechnolab.com/2011/03/04/android/android-load-image-from-url/.

I used the code below to fetch the image from a url but it doesn't working for large images.

Am I missing something when fetching that type of image?

imgView = (ImageView)findViewById(R.id.ImageView01);
  imgView.setImageBitmap(loadBitmap("http://www.360technosoft.com/mx4.jpg"));

  //imgView.setImageBitmap(loadBitmap("http://sugardaddydiaries.com/wp-content/uploads/2010/12/how_do_i_get_sugar_daddy.jpg"));
     //setImageDrawable("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg");
  //Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
  //imgView.setImageDrawable(drawable);

 /* try {
     ImageView i = (ImageView)findViewById(R.id.ImageView01);
     Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg").getContent());
     i.setImageBitmap(bitmap); 
   } catch (MalformedURLException e) {
     System.out.println("hello");
   } catch (IOException e) {
    System.out.println("hello");
   }*/
    }


 protected Drawable ImageOperations(Context context, String string,
   String string2) {
  // TODO Auto-generated method stub
  try {
   InputStream is = (InputStream) this.fetch(string);
   Drawable d = Drawable.createFromStream(is, "src");
   return d;
  } catch (MalformedURLException e) {
   e.printStackTrace();
   return null;
  } catch (IOException e) {
   e.printStackTrace();
   return null;
  }

 }
