小賴的實戰記錄

Android要顯示網路圖片。

首先，

要建立ImageView

然後，撰寫抓取網路圖片的函式如下

public class ImgUtils {
    //讀取網路圖片，型態為Bitmap
    public static Bitmap getBitmapFromURL(String imageUrl){
       try 
       {
          URL url = new URL(imageUrl);
          HttpURLConnection connection = (HttpURLConnection) url.openConnection();
          connection.setDoInput(true);
          connection.connect();
          InputStream input = connection.getInputStream();
          Bitmap bitmap = BitmapFactory.decodeStream(input);
          return bitmap;
       } 
       catch (IOException e) 
       {
          e.printStackTrace();
          return null;
       }
    }
}

取ImageView 

ImageView img = (ImageView)view.findViewById(R.id.img);

設定image

img.setImageBitmap(ImgUtilsgetBitmapFromURL(image_url));
