Question

When i first create an android studio project, there should be a pre made layout preview in the activity_main.xml, but i only see a grey screen with the words 'Hello World'.

but it should look like this...

How do i fix this? I tried restarting my computer and pressing reload in android studios, but nothing is working. Does anyone have any ideas?
