Android 网络显示图片 通过代理访问
主要的代码参考：http://www.cnblogs.com/hnrainll/archive/2012/05/28/2522558.html
重点看如何在Android代码中设置代理。
代码如下：
1 public class MainDemo extends Activity { 2 /** Called when the activity is first created. */ 3 4 private ImageView imageView = null; 5 6 private String urlString = "http://s7.sinaimg.cn/middle/9b82a8c54c10ecacbb686&960"; 7 8 @Override 9 public void onCreate(Bundle savedInstanceState) { 10 super.onCreate(savedInstanceState); 11 setContentView(R.layout.main); 12 13 imageView = (ImageView) findViewById(R.id.imageview01); 14 imageView.setImageBitmap(returnBitmap(urlString)); 15 } 16 17 public Bitmap returnBitmap(String url) { 18 Bitmap bm = null; 19 20 try { 21 HttpURLConnection conn = getUrlConnection(url); 22 conn.setDoInput(true); 23 conn.connect(); 24 InputStream is = conn.getInputStream(); 25 bm = BitmapFactory.decodeStream(is); 26 is.close(); 27 } catch (IOException e) { 28 // TODO Auto-generated catch block 29 e.printStackTrace(); 30 } 31 32 return bm; 33 } 34 35 private HttpURLConnection getUrlConnection(String url) { 36 java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP, 37 new InetSocketAddress("172.20.220.2", 38 8080)); 39 try { 40 return (HttpURLConnection) new URL(url).openConnection(p); 41 } catch (MalformedURLException e) { 42 // TODO Auto-generated catch block 43 e.printStackTrace(); 44 } catch (IOException e) { 45 // TODO Auto-generated catch block 46 e.printStackTrace(); 47 } 48 return null; 49 } 50 }
