title: EditText with history
body: <p>I want to show the history of text introduced in a TextView. It should be something similar to the search bar on google play:</p>
  
  <p><img src="https://i.stack.imgur.com/XQ00w.png" alt="google play search"></p>
  
  <p>By the moment I'm using an AutoCompleteTextView with android:completionThreshold="1", but I would like to don't need to write any text before suggestions starts.</p>
  
  <p>Any ideas??</p>
