title: Implementing events Spinner with Butter Knife
body: <p>First: We need to reference the spinner</p>
  
  <pre><code>@Bind(R.id.field_type_id)
  Spinner mTypeIdSpinner;
  </code></pre>
  
  <p>Second: Create string array</p>
  
  <pre><code>&lt;string-array name="type_id_array"&gt;
      &lt;item&gt;One&lt;/item&gt;
      &lt;item&gt;Two&lt;/item&gt;
      &lt;item&gt;Three&lt;/item&gt;
      &lt;item&gt;Four&lt;/item&gt;
      &lt;item&gt;Five&lt;/item&gt;
  &lt;/string-array&gt;
  </code></pre>
  
  <p>Third: Load the adapter in your activity (onCreate method for example)</p>
  
  <pre><code>private void loadSpinnerIdTypes() {
      ArrayAdapter&lt;CharSequence&gt; adapter = ArrayAdapter.createFromResource(this,
              R.array.type_id_array, android.R.layout.simple_spinner_item);
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
      mTypeIdSpinner.setAdapter(adapter);
  }
  </code></pre>
  
  <p>Fourth: Listen the events</p>
  
  <pre><code>@OnItemSelected(R.id.field_type_id)
  void onItemSelected(int position) {
      Timber.d("Element selected %s ", mTypeIdSpinner.getItemAtPosition(position));
  }
  </code></pre>
