title: android - volley request inside loop
body: <p>Okay, my first post because I've reached the limits of researching.
  I try to run 3 requests, each with a different url inside a for loop (I've tried also with while and if) and the code runs perfectly, untiiiiil it gets to the requestqueue. Now the thing is: after the request queue I want to get the response, and only then make the for loop again, but that does not seem to be what the program wants to do, because after I add the requestqueue, the class goes back to the for loop, and continues the whole function until the end, and only in the end I get 3 followed responses, and it is pissing me off, because I want the requests one at each time. I've done many requests before, and thought I knew how to work this out, but I can't =s
  Code:</p>
  
  <pre><code>public class MainActivity extends FragmentActivity {
  
  private String totalresults, word, results, server, userAgent, quantity, urly, nome;
  private int counter,limit;
  EditText nome_empresa;
  public TextView output;
  ProgressDialog PD;
  ViewPager viewPager=null;
  public ArrayList half_cards, all_cards;
  
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      nome_empresa = (EditText) findViewById(R.id.nome_empresa);
      output = (TextView) findViewById(R.id.output);
      PD = new ProgressDialog(this);
      PD.setMessage("Loading....");
      PD.setCancelable(false);
      //viewPager = (ViewPager) findViewById(R.id.pager);
      //FragmentManager fragmentManager = getSupportFragmentManager();
      //viewPager.setAdapter(new MyAdapterAlfa(fragmentManager));
  
  }
  
  
  
  public void vamos(View view) {
      nome = nome_empresa.getText().toString();
      PD.show();
      googlesearch(nome, 200, 0);
      ListView lv = (ListView) findViewById(R.id.custom_list_view);
  
      lv.setAdapter(new ArrayAdapter&lt;String&gt;(MainActivity.this,
              android.R.layout.simple_list_item_1, all_cards));
      all_cards = get_cards(totalresults, nome);
      PD.dismiss();
  
  }
  
  public void googlesearch(String worde, int limite, int start) {
      word = worde;
      results = "";
      totalresults = "";
      server = "www.google.com";
      userAgent = "(Mozilla/5.0 (Windows; U; Windows NT 6.0;en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6";
      quantity = "100";
      counter = start;
      limit = limite;
      do_search();
  }
  
  public void do_search() {
  
      for(int l=counter; l&lt;=limit; l+=100){
          urly = "http://" + server + "/search?num=" + quantity + "&amp;start=" + Integer.toString(counter) + "&amp;hl=en&amp;meta=&amp;q=%40\"" + word + "\"";
          RequestQueue requestQueue = Volley.newRequestQueue(this);
          StringRequest strReq = new StringRequest(Request.Method.GET, urly, new Response.Listener&lt;String&gt;() {
              @Override
              public void onResponse(String response) {
                  try {
                      half_cards = get_cards(response, word);
                      all_cards.addAll(half_cards);
                  } catch (Exception e) {
                      e.printStackTrace();
                  }
  
              }
          }, new Response.ErrorListener() {
  
              @Override
              public void onErrorResponse(VolleyError error) {
                  VolleyLog.e("Error: " + error.getMessage());
              }
          });
              requestQueue.add(strReq);
      }

      return rawres.cards();
