進捗バーを入れる方法

Question

私はアプリケーションに進捗バーを置くことができますが、私は検索しましたが、私はAsyncTaskだけを取得しています。以下のコードでは、プログレスバーをどのように置くか、私は取得していません。詳細については、

 @Override 
     public void onClick(View view) { 
      EditText e1 = (EditText) findViewById(R.id.input_email); 
      EditText p1 = (EditText) findViewById(R.id.input_password); 
      email = e1.getText().toString(); 
      String password = p1.getText().toString(); 

      String url = "url" 
      AQuery mAQuery = new AQuery(main.this); 
      mAQuery.ajax(url, String.class, new AjaxCallback<String>() { 

       @Override 

       public void callback(String url, String data, AjaxStatus status) { 

        super.callback(url, data, status); 

        String StringData = "" + data; 

         if(StringData.equals("\"S\"")){ 
          Intent intent = new Intent(main.this, MainActivity.class); 
          intent.putExtra("emailid",email); 


          startActivity(intent); 
         } 
         else{ 
          Toast toast = Toast.makeText(main.this,"Invalid Combination of Email and Password", Toast.LENGTH_LONG); 
          toast.setGravity(Gravity.CENTER, 0, 0); 
          toast.show(); 
         } 

        }

あなたはこのクラスとして行うことができます
