title: Get ArrayList<HashMap<String, String>> values
body: <p>In my first activity I have the next code:</p>
  
  <pre><code>ArrayList&lt;HashMap&lt;String, String&gt;&gt; list_params = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;();
              HashMap&lt;String, String&gt; param_aux = new HashMap&lt;String, String&gt;();
  
              param_aux.put("language", Integer.toString(language_spinner.getSelectedItemPosition()));
              param_aux.put("city", city_edittext.getText().toString());
  
  list_params.add(param_aux);
  </code></pre>
  
  <p>And in my second activity I want to get the values, so my code is:</p>
  
  <pre><code>ArrayList&lt;HashMap&lt;String, String&gt;&gt; list_params_ = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;();
      list_params_= (ArrayList&lt;HashMap&lt;String, String&gt;&gt;) getIntent().getSerializableExtra("list_params");
  
      System.out.println("...serialized data.."+list_params_);
  </code></pre>
  
  <p>If I chech the System.out, the values are correct sent but I want to get a specific value of the HashMap (example: city value).</p>
  
  <pre><code>...serialized data..[{weekend_midday_check=1, weekend_afternoon_check=0, weekend_morning_check=1, sort_by=0, language=0, weekly_afternoon_check=1, weekly_morning_check=1, weekly_midday_check=1, city=Terrassa}]
  </code></pre>
  
  <p>How can I get the value for the city sent in the first activity?</p>
