MainActivityのメソッドを他のクラスと分離するにはどうすればいいですか？

Question

私はこのようなメソッドを呼び出します。

finishedFlag = new HttpUtil().execute(url, userid, workflag).get();

と私は別のクラスにこのメソッドを区切るしたいです。 （例：クラスを作成：httpUtil）

私はどのようにして電話をかけてもらえますか？

public class HttpUtil extends AsyncTask<String, Void, Boolean> { 
     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      // Showing progress dialog 
      pDialog = new ProgressDialog(MainActivity.this); 
      pDialog.setMessage("ing..."); 
      pDialog.setCancelable(false); 
      pDialog.show(); 
     } 

     @Override 
     public Boolean doInBackground(String... params1) { 
      try { 

       String url = params1[0]; 
       URL obj = new URL(url); 
       HttpURLConnection conn = (HttpURLConnection) obj.openConnection(); 

       conn.setReadTimeout(10000); 
       conn.setConnectTimeout(15000); 
       conn.setRequestMethod("POST"); 
       conn.setDoInput(true); 
       conn.setDoOutput(true); 
       conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 

       ArrayList<NameValuePair> params = new ArrayList<NameValuePair>(); 

       if (params1[0].equals(aaa)) {      
        params.add(new BasicNameValuePair("time", params1[2])); 
        params.add(new BasicNameValuePair("userid", params1[1])); 
       } else if (params1[2].equals("goWork")) { 
        Thread.sleep(300); 

        params.add(new BasicNameValuePair("userid", params1[1])); 
       } 
       if (params1[2].equals("3")) { 
        params.add(new BasicNameValuePair("userid", params1[1])); 
       } 

       OutputStream os = conn.getOutputStream(); 
       BufferedWriter writer = new BufferedWriter(
         new OutputStreamWriter(os, "UTF-8")); 
       writer.write(getQuery(params)); 
       writer.flush(); 
       writer.close(); 
       os.close(); 

       InputStream is = conn.getInputStream(); 
       BufferedReader br = new BufferedReader(new InputStreamReader(is)); 
       String line; 
       StringBuffer response = new StringBuffer(); 
       while ((line = br.readLine()) != null) { 
        response.append(line); 
       } 
       br.close(); 

       String res = response.toString(); 

       HashMap<String, String> myHashMap = new HashMap<String, String>(); 
       myHashMap = convertToHashMap(res); 

       String errmsg = ""; 
       String errmsg2 = ""; 
       String name = ""; 
       String OutToWork = ""; 

       if (params1[2].equals("goWork")) { 
        errmsg = myHashMap.get(" errmsg"); 
        errmsg2 = myHashMap.get(" errmsg2"); 
       } else if (params1[0].equals(url4end_work)) { 
        String outWork = loadJSONFromAsset(params1[2]);

ねえ、あなたは、バックグラウンド処理（あなたがそれをやった）に対処し、活動/フラグメントでデータを取得するためのインタフェースのコールバックを作成するための非同期アダプタを拡張するクラスを作成する必要があります。

これはAsyncTaskクラスです：

public class HttpUtilClass extends AsyncTask<String, Void, Boolean> { 

    TestListener testListener; 
    Activity activity; 

    public HttpUtilClass(Activity activity){ 
     this.activity = activity; 
     testListener =(TestListener) activity; 
    } 

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

    @Override 
    protected Boolean doInBackground(String... strings) { 

     return false; 
    } 

    @Override 
    protected void onPostExecute(Boolean aBoolean) { 
     super.onPostExecute(aBoolean); 
     if (testListener!=null){ 
      testListener.getBool(aBoolean); 
     } 
    } 
} 

これはインターフェイスです：

public interface TestListener { 

    void getBool(boolean bool); 
} 

これはあなたの主な活動

public class MainActivity extends AppCompatActivity implements TestListener{ 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     HttpUtilClass hh = new HttpUtilClass(this); 
     hh.execute("test"); 
    } 

    @Override 
    public void getBool(final boolean bool) { 
     this.runOnUiThread(new Runnable() { 
      @Override 
      public void run() { 
       Log.i("LOG", "getBool: " + bool); 
      } 
     }); 

    } 
} 

幸運である;）
