android在沒有AsyncTask的情況下執行HTTP請求？

Question

我的應用程序從服務器獲取多的Json信息

目的尋找任何方式不AsyncTask執行Http要求，有沒有辦法做到這一點還是我一直在使用AsyncTask到從服務器獲取的Json信息，以保持？

Answer 1

我建議採取看看Android Asynchronous Http Client (Loopj) library。這是一個「典型」http請求的例子。

AsyncHttpClient client = new AsyncHttpClient(); 
client.get("http://www.google.com", new AsyncHttpResponseHandler() { 
    @Override 
    public void onSuccess(String response) { 
     System.out.println(response); 
    } 
}); 

Answer 2

這是如何ü可以做到這一點

public class RequestClient extends AsyncTask<String, Void, String>{ 
    Context context; 

    public RequestClient(Context c) { 
     context = c; 
    } 

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

    @Override 
    protected String doInBackground(String... aurl){ 
    String responseString=""; 
    HttpClient client = null; 
    try { 
     client = new DefaultHttpClient(); 
     HttpGet get = new HttpGet(LoginActivity.url); 
     HttpResponse responseGet = client.execute(get); 
     HttpEntity resEntityGet = responseGet.getEntity(); 
     if (resEntityGet != null) { 
      responseString = EntityUtils.toString(resEntityGet); 
      Log.i("GET RESPONSE", responseString.trim()); 
     } 
    } catch (Exception e) { 
     Log.d("ANDRO_ASYNC_ERROR", "Error is "+e.toString()); 
    } 
     Log.d("ANDRO_ASYNC_RESPONSE", responseString.trim()); 
     client.getConnectionManager().shutdown(); 
    return responseString.trim(); 

    } 


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

和u必須從主類稱其爲

RequestClient reqClient = new RequestClient(this); 
reqClient.execute().get();
