從互聯網更新textview

Question

我想製作一個TextView或Imageview從互聯網上請求信息，就好像它是一個每天更新的newspapper，我想做類似的事情，但我不知道如何。

我想我應該有一個服務器或東西，但有人可以解釋我的過程？以及哪個服務器或做什麼？

first you need to enable the permission in the android manifest 
<uses-permission android:name="android.permission.INTERNET" /> 
than you can use a textView like this 
new Thread() { 
      @Override 
      public void run() { 
       String path ="http://host.com/info.txt"; // your webpage with text 
       URL u = null; 
       try { 
        u = new URL(path); 
        HttpURLConnection c = (HttpURLConnection) u.openConnection(); 
        c.setRequestMethod("GET"); 
        c.connect(); 
        InputStream in = c.getInputStream(); 
        final ByteArrayOutputStream bo = new ByteArrayOutputStream(); 
        byte[] buffer = new byte[1024]; 
        in.read(buffer); // Read from Buffer. 
        bo.write(buffer); // Write Into Buffer. 

        runOnUiThread(new Runnable() { 
         @Override 
         public void run() { 
          TextView text = (TextView) findViewById(R.id.TextView1); 
          text.setText(bo.toString()); 
          try { 
           bo.close(); 
          } catch (IOException e) { 
           e.printStackTrace(); 
          } 
         } 
        }); 

       } catch (MalformedURLException e) { 
        e.printStackTrace(); 
       } catch (ProtocolException e) { 
        e.printStackTrace(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 

      } 
}.start();
