title: Android search list while typing
body: <p>How can I build a search bar where while I'm typing the results are shown in the <code>ListView</code> in which I'm searching?</p>
  
  <p>For example, I have a list view with 20 strings. I press the search key and appears the bar. I want when I type 3 words or more the search starts running showing the results in the list view (as a filter: only shows the strings in the list that matching what I type)</p>
