title: How to check if my EditText has a TextChangedListener (TextWatcher)?
body: <p>I know we can add a <code>TextWatcher</code> to <code>EditTexts</code> using <code>addTextChangedListener</code> and remove it using <code>removeTextChangedListener</code>. But now I want to check if my <code>EditText</code> has any <code>TextWatcher</code> or not.</p>
  
  <p>How can I do that?</p>
  
  <p>I have a grid. It has an adapter. My adapter checks if the type of defined item is EditText add a <code>TextWatcher</code> to it. When method <code>getView</code> is called <code>TextWatcher</code> is added to that <code>EditText</code>. I want to avoid adding extra <code>TextWatchers</code> if one is added.</p>
