fixed the issue. Will look into that further You have to make class like this for handling 2nd spinner according to your 1st spinner result
code :
public class Lecturer{
String name;
ArrayList course;
Lecturer(String name,Arraylist course){
this.name= name;
this.course = course;
    }

public String toString(){
return name;
}
}
ArrayList<Lecturer> lecturerList = new ArrayList<>();
list.add(new Lecturer("ardi halim",<courses list for ardi halim>));
list.add(new Lecturer("fanny",<courses list for fanny>));

set lecturerList for 1st spinner
then
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        ArrayList courselist = ((Lecturer)spinner1.getSelectedItem()).course;
                set courselist for spinner2 adapter
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });
