Showing xml for correct view

When a user logs in to my app, they can either click the view students button or daily grading button. The view students will display a student’s image and their name. The daily grading will display the student’s image, name, and two checkboxes that says pass or fail. Now the issue I have is that the checkboxes for pass and fail are showing up in my activity_view_students.xml view when it should not be. It should only show when a user clicks daily grading. I will put images below to make it clearer

What it looks like in the activity_view_students.xml

What it should look like in activity_view_students.xml

I will paste all relevant code below.

Answer

You can simply use different adapters create another activity_student_item.xml let’s say activity_view_student_item.xml and remove the checkboxes from that one create another adapter for that recyclerView but change

View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.activity_student_item,parent,false);

in the new adapter to

View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.activity_view_student_item,parent,false);

and in the ViewStudents activity set the recycler’s Adapter to that new adapter
