How to show a ListFragment on top right screen when user click a button
<p>I want to show a ListFragment when user click a button on the top right corner.
When user select a item in this ListFragment or just touch the screen outside the ListFragment, the ListFragment should be disappeared.</p>

<p>Just like below</p>

(i don't have rights to post an image, so I have uploaded it to my blog)</p>

<p>I tried to use DialogFragment to wrap the ListFragment, but I find no way to set the dialog's position, it always shows in the center, I need to display the ListFragment on the top right of screen.</p>

<p>And I also tried to use PopupWindow, but I don't know how to set a ListFragment as popupwindows' contentview.</p>

<p>So, my questions are:</p>

<ol>
<li>how to show a ListFragment when user click a button, this
ListFragment should be shown at top right corner.</li>
<li>how to hide this ListFragment when user select a item of this ListFragment or touch
the screen outside the ListFragment.</li>
</ol>

<p>Sorry for my poor English :)</p>
