無法顯示URL圖像（位圖）

我想顯示我的形象，但它並沒有顯示：無法顯示URL圖像（位圖）

public Bitmap getUserPic(String picID) { 
    String imageURL; 
    Bitmap bitmap = null; 
    Log.d("BITMAP", "Loading Picture"); 
    imageURL = picID; 
    Log.d("image url", picID); 
    try { 
     bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageURL).getContent()); 
    } catch (Exception e) { 
     Log.d("BITMAP", "Loading Picture FAILED"); 
     e.printStackTrace(); 
    } 
    return bitmap; 
}

logcat的輸出：（？我如何顯示我的logcat輸出更整潔）

當應用程序嘗試在其主線程上執行聯網操作時，會引發異常。僅適用於定位到Honeycomb SDK或更高版本的應用程序。針對早期SDK版本的應用程序允許在其主要事件循環線程上進行聯網，但非常不鼓勵。

使用AsyncTask獲取單獨線程上的圖像，然後將其分配到以在onPostExecute和Voila上顯示！它應該工作。

請參閱本作異步任務：http://android-developers.blogspot.in/2009/05/painless-threading.html

有一個骯髒的修復，但我會建議從來沒有使用這個

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 

StrictMode.setThreadPolicy(policy);

試試這個：

AQuery aq = new AQuery(getActivity()); 
     aq.id(view.findViewById(R.id.image)).image(imageUrl, true, true, 0, 0, 
       new BitmapAjaxCallback() { 
        @Override 
        public void callback(String url, ImageView iv, Bitmap bm, AjaxStatus status){ 
         iv.setImageBitmap(bm); 
        } 
       }.header("User-Agent", "android"));
