Android:How to use Class<? extends Activity> as a variable type in Parcelable

Question

I'm having problem about writing and reading a variable whose type is Class<? extends Activity> but I could find any solution for this.

clas is variable name whose type is Class<? extends Activity>. I'm using this variable for opening related activity, when an student clicked in a listactivity

There is no function like Parcelable.readClass() or writeClass() can anyone help please to solve this

Thx in advance

Here is my Student.java

public class Student {
    private String id;
    private Class<? extends Activity> clas;

    ...

}

Here I created ParcalebleStudent.java

public class ParcalebleStudent implements Parcelable {
    private Student student;

    ....

    private ParcalebleStudent(Parcel in) {
        student = new Student();
        student.setId(in.readString());
        student.setClas(in.readWhat?????????);//I need help here
    }

    @Override
    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeString(student.getId());
        parcel.writeWhat???????(student.getClas());//and here

    }
}

Answer 1

You can use parcel.writeString(student.getClas().getName()); and student.setClas(Class.forName(in.readString());

Answer 2

Class is Serializable, so you could use writeSerializable and readSerializable. You'll then have to cast it back to Class<? extends Activity>. Most IDEs will give you an unsafe cast warning, but there's not a great way to do it in a manner where you avoid that warning.
