[Solved] My ListView is null and i don’t get why

so i solved the problem . first of all , just to clear the air up , the list view variable was null when i tried to initialize it with my xml file . my mistake was that i had the listview xml file as a stand alone file , there was no formatting to it. so basically my mistake was not placing the ListView tags inside the content xml file that i was using . All i had to do was add the ListView tag to my content xml file
