title: AutoCompleteTextView: Filter results from a previously made list of suggestions
body: <p>I am looking for a method for filtering results from a previously made list of suggestions. Currently, I have done this with a "AutoCompleteTextView", but it does not do exactly what I want. AutoCompleteTextView works with "strings begining with" and I want that it works with "string containing". I show below an exmaple of what I have and what I want:</p>
  
  <hr>
  
  <p>[List of suggestions]
  aaa, baa, caa, daa, ddd</p>
  
  <hr>
  
  <p>[What happens when using AutoCompleteTextView]</p>
  
  <p>User looks for "a" and appears as a suggestion: "aaa".</p>
  
  <hr>
  
  <p>[What I want]</p>
  
  <p>User looks for "a" and appears as a suggestion: "aaa", "baa", "caa", "daa".
  The user continues typing and looks for "aa" and appears: "aaa", "baa", "caa", and "daa". The user continue typing and looks for "aaa" and only appears "aaa".</p>

  <p>Any reference or documentation is enough, I am not looking for my work to be done by the community.</p>
  
  <p>Thank you very much.</p>
