從Android中獲取Html來自網絡

我想從網頁獲取HTML，但我不能。這裏是我的代碼從Android中獲取Html來自網絡

final EditText et = (EditText) findViewById(R.id.editText1); 
    final TextView tv = (TextView) findViewById(R.id.textView1); 
    final Button b = (Button) findViewById(R.id.button1); 
    b.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 

      try { 
       URL url = null; 
       url = new URL(et.getText().toString()); 
       URLConnection conn = url.openConnection(); 
       BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
       String line; 
       while ((line = reader.readLine()) != null) { 
        tv.append(line); 

       } 
      } catch (Exception e) { 
       Log.e("error", "erorr connection "+ e.toString()); 
      }    
     } 
    });

我也加入了來自互聯網的許可。目標版本4.0.3

請把網絡部件到後臺線程，然後更新到前臺UI線程。您可以使用AsyncTask來執行此操作。

//創建HTTP客戶端

HttpClient httpclient = new DefaultHttpClient(); 
    HttpGet httpget = new HttpGet("http:// yoururl"); 
    HttpResponse response = httpclient.execute(httpget); 
    HttpEntity entity = response.getEntity(); 
    InputStream is = entity.getContent(); 
    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8); 
    StringBuilder sb = new StringBuilder(); 
    String line = null; 
    while ((line = reader.readLine()) != null) 
     sb.append(line + "\n"); 

    String resString = sb.toString(); // Result is here 

    is.close(); // Close the stream
