title: listview filter in android
body: <p>I am making an application with Edittext and Listview in android app.
  When I search text in edittext then the listview will filter all the words that start with that text.
  Example:</p>
  
  <ul>
  <li>apple</li>
  <li>application</li>
  <li>book an</li>
  <li>can</li>
  </ul>
  
  <p>when i type: a , the result i want is to filter all the word that start with a only:</p>
  
  <ul>
  <li>apple</li>
  <li>application</li>
  </ul>
  
  <p>when I use : adapterlv.getFilter().filter(txtword.getText());
  it filter all the word that contain a.
  So, how can i do this?</p>
