Fix crash when casting class extending activity

Fix #102

chinalwb commented 4 years ago

@starshipcoder Thanks for this amazing PR! It works but I cannot fully understand how the below code works:

       ....
        while (!(context instanceof Activity)) {
            context = ((ContextWrapper)context).getBaseContext();
        }
        ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
       .....

Could you please help explain more about the code? Thanks!
