如何从web中读取android中的文本文件？

Question

我是新来的android.I需要从Web读取文本文件并显示该文本文件。有没有可能在android中直接查看文本文件。或者如何阅读和显示android textview中的文本文件？

Answer 1

使用DefaultHttpClient httpclient = new DefaultHttpClient();

HttpGet httppost = new HttpGet("http://www.urlOfThePageYouWantToRead.nl/text.txt"); 
HttpResponse response = httpclient.execute(httppost); 
     HttpEntity ht = response.getEntity(); 

     BufferedHttpEntity buf = new BufferedHttpEntity(ht); 

     InputStream is = buf.getContent(); 


     BufferedReader r = new BufferedReader(new InputStreamReader(is)); 

     StringBuilder total = new StringBuilder(); 
     String line; 
     while ((line = r.readLine()) != null) { 
      total.append(line + "\n"); 
     } 

     TextView.setText(total); 

希望这有助于设置文本中一个TextView做什么分开！

@BadSkillz是正确的，但在最后的API 9使其错误：

android.os.NetworkOnMainThreadException 

，因为您必须在另一个线程联网操作，因为在主线程联网，使您的应用程序没有响应的任何请求的时间，所以你可以添加这个类到你的活动：

private class GetStringFromUrl extends AsyncTask<String, Void, String> { 

    ProgressDialog dialog ; 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 

     // show progress dialog when downloading 
     dialog = ProgressDialog.show(MainActivity.this, null, "Downloading..."); 
    } 

    @Override 
    protected String doInBackground(String... params) { 

     // @BadSkillz codes with same changes 
     try { 
      DefaultHttpClient httpClient = new DefaultHttpClient(); 
      HttpGet httpGet = new HttpGet(params[0]); 
      HttpResponse response = httpClient.execute(httpGet); 
      HttpEntity entity = response.getEntity(); 

      BufferedHttpEntity buf = new BufferedHttpEntity(entity); 

      InputStream is = buf.getContent(); 

      BufferedReader r = new BufferedReader(new InputStreamReader(is)); 

      StringBuilder total = new StringBuilder(); 
      String line; 
      while ((line = r.readLine()) != null) { 
       total.append(line + "\n"); 
      } 
      String result = total.toString(); 
      Log.i("Get URL", "Downloaded string: " + result); 
      return result; 
     } catch (Exception e) { 
      Log.e("Get Url", "Error in downloading: " + e.toString()); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     super.onPostExecute(result); 

     // TODO change text view id for yourself 
     TextView textView = (TextView) findViewById(R.id.textView1); 

     // show result in textView 
     if (result == null) { 
      textView.setText("Error in downloading. Please try again."); 
     } else { 
      textView.setText(result); 
     } 

     // close progresses dialog 
     dialog.dismiss(); 
    } 
} 

和使用，每次你想一击线：

new GetStringFromUrl().execute("http://www.google.com/");
