intent.putExtra("SelectMode", true);
startActivityForResult(intent, REQUEST_CODE_STUDENTS_SELECTION);
return true;
}

case REQUEST_CODE_STUDENTS_SELECTION: {
ClassDetailsFragment fragment = (ClassDetailsFragment)
getFragmentManager().findFragmentByTag(FRAGMENT_TAG_CLASS_DETAILS);
ArrayList<Long> selectedStudentIds = (ArrayList<Long>)
data.getSerializableExtra("StudentIds");
DbHelper dbHelper = new DbHelper(getBaseContext());
for (int i = 0; i < selectedStudentIds.size(); i++) {
boolean addStudent = true;
for (int j = 0; j < classStudents.size(); j++) {
if (classStudents.get(j).student.id ==
selectedStudentIds.get(i)) {
addStudent = false;
break;
}
}
if (addStudent) {
data get from database
classStudents.add(classStudent);
}
}
fragment.newAddedStudents(classStudents);
// adapterClassStudents.notifyDataSetChanged();
dbHelper.close();
