How to add a select all button to a custom Listview
<p>I have a custom listView in my app I would like to implement my select all button I have created.</p>

<p>My ListView looks like.</p>

<p>[(Image)(Text)(CheckBox)]</p>

<p>I have looked at some similar questions, the most common answer was with the user of the <code>notifyDataSetChanged ()</code> method, iv'e tried researching and implementing without any luck, I was wondering can you think of a way round it or give me an example of how I can implement the method</p>
