ANDROID：從解析圖像獲取Android圖像

我創建了一個ListView。當我單擊ListView的單個項目時，我將調用一個活動來顯示單個項目View。 TextView數據正在解析。但是當我試圖調用一個圖像來解析它的不加載時（該圖像在線存放在一個單獨的位置）。如果任何人可以請告訴如何在這裏加載圖像？ANDROID：從解析圖像獲取Android圖像

我的文件URL

url = new URL("file location " + statusObject.getString("image"));

編輯的代碼

URL url = null; 
        try { 
         url = new URL("https://www.gravatar.com/avatar/db5bfe41c9d21d3a5b4e5b5f6a2d776d?s=32&d=identicon&r=PG&f=1"); 
        } catch (MalformedURLException e1) { 
         e1.printStackTrace(); 
        } 
        Bitmap bmp = null; 
        try { 
         bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream()); 
        } catch (IOException e1) { 
         e1.printStackTrace(); 
        } 
        txtv2.setImageBitmap(bmp);

有U使用解析對象 – Athul

最後這段代碼編輯的一些代碼工作後形成答案的鏈接。通過此代碼你可以爲每個Object id動態圖像動態。

URL url = null; 
         try { 
          url = new URL("image url" + object.getString("image")); 
         } catch (MalformedURLException e1) { 
          e1.printStackTrace(); 
         } 
         Bitmap bmp = null; 
         try { 
          bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream()); 
         } catch (IOException e1) { 
          e1.printStackTrace(); 
         } 
         txtv2.setImageBitmap(bmp); 

         // something went wrong

在Manifest.xml定義<uses-permission android:name="android.permission.INTERNET" />。

然後使用Picasso或Gilde，並從各自的實例解析圖像，並通過圖像URL你是從解析查詢。這些庫將解析URL並在ImageView中返回圖像。

你的第一個鏈接一些編輯工作後，得到URL中檢索..但僅適用於一個佔位符圖像，你可以告訴如何佈置動態圖像檢查我的問題，我更新@Sneh Pandya –
