title: Retrieve ArrayLIst which is a value in HashMap
body: <p>I have a <code>HashMap</code> <code>HashMap&lt;Integer, ArrayList&lt;Bundle&gt;&gt; hashMap</code> I am able to put values in the <code>HashMap</code> . And the hashmap is passed to the next class . Now how to get the <code>ArrayList</code> of <code>Bundle</code>  from <code>HashMap</code>. Any how I am using <code>Iterator</code> <code>Set</code> . Still I am not able to list the values of HashMap which is an arraylist.    This is actually am Message picker . And I have multiselection mode on using callback for listview. When I click on a sms list , I need to get some details and store it in a <code>hashmap</code> . There might be chance that a sms can have multiple recepinets. The <code>key</code> will be position .  I need to take all the values of the <code>HashMap</code> that is <code>ArrayList</code> into one single <code>ArrayList</code>. Say int the 0th position we have [0,[A,B]] ,[1,[C,D]]  , i want to create a new arraylist and store A , B, C, D in it.</p>
