最满意答案

您是否在清单上获得了互联网许可

并在后台运行此代码，如asyn任务

class LoadImageLoader extends AsyncTask<Void, Void, Void>{ @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub drawable = LoadImage("http://i.imgur.com/DvpvklR.png"); return null; } @Override protected void onPostExecute(Void result) { // TODO Auto-generated method stub super.onPostExecute(result); imgview.setImageDrawable(drawable); } }

Are you given internet permission on manifest

and running this code in background such as asyn task

class LoadImageLoader extends AsyncTask<Void, Void, Void>{ @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub drawable = LoadImage("http://i.imgur.com/DvpvklR.png"); return null; } @Override protected void onPostExecute(Void result) { // TODO Auto-generated method stub super.onPostExecute(result); imgview.setImageDrawable(drawable); } }
