如何删除XML Android中列表项之间的透明行

I am linking image and text together to display in a fragment. Everything works just fine except for this transparent line that appears under each item. This line shows the layout of the activity which the fragment is called from. How can I make this fundraiser.xml take up all the screen, no matter how many items in my list and how to I get rid of that line after each item? I have uploaded an image to better explain my problem I am linking image and text together to display
