title: How to execute a method for each item in a listview
body: <p>I have an <code>ArrayAdapter&lt;MyService&gt;</code> and to each item in <code>listView</code> I have one button that executes a async call to download a file by http request, this is working pretty well.</p>
  
  <p>Now, I created a button "Download All" in the Activity, I would like this button to execute all items in the <code>listView</code>, but I have no idea how to do that. Should I iterate through the list, get the button view and call its click?</p>
  
  <p>I would like to have some suggestions.</p>
