title: How to Create a Multiple Choice Android List View with result gotten from Mysql database using PHP?
body: <p>i have gone through numerous ariticles both on google and here at stack overflow,but i can't seem to find a solution to my problem.The code fragment i'm about to place below is a tutorial i studied and decided to expand it.I have tried converting the listview to a multiple choice listview,but can't seem to go around that.I don't want to create a custom adapter with a layout containing a checkbox as it would be more complicated for me.</p>
