How to make RealmList item as list view in adapter?

[kentcheung2000]

I am still having a problem of how to list the realmList in my studentAdapter...I know how to list individual objects in viewholder in school adapter. I don't know how list the data from Students and put it in my student adapter which is similar to school adapter.

The StudentActivity is as followed:

@Override
public void onResume(){
    super.onResume();

    Bundle extras = getIntent().getExtras();

    if (extras != null)
    {
        String schoolName = extras.getString("schoolName");
        Log.d(tag, String.valueOf(schoolName));
    }

   I can get the school name but I don't know how to get the students name and list it as lisview in my student adapter.  Please help...

The MainActivity is as followed:

.......
@Override
public void onResume(){


    super.onResume();

    if(mAdapter == null) {
        List<School> schools = null;
        try {
            schools = loadSchools();

        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    RealmResults<School> schools = realm.where(School.class).findAll();
    final SchoolAdapter adapter = new SchoolAdapter(this, R.id.schools_list, schools, true);
    ListView listView = (ListView) findViewById(R.id.schools_list);
    listView.setAdapter(adapter);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {


        public void onItemClick(AdapterView<?> adapterView, View view,
                                int position, long id) {

         String schoolName  = adapter.getRealmResults().get(position).getSchoolName();

            startStudentList(schoolName);

        }
    });
}


public void startStudentList(String schoolName){

    //String schoolName = school.getSchoolName();

    Intent schoolIntent = new Intent(this, StudentActivity.class);

    schoolIntent.putExtra("schoolName", schoolName);


    startActivity(schoolIntent);
   }

The SchoolAdapter is as followed:

public class SchoolAdapter extends RealmBaseAdapter<School> implements ListAdapter {

private static class ViewHolder{
    TextView school;
}

public SchoolAdapter(Context context, int resId, RealmResults<School> realmResults, boolean automaticUpdate) {
    super(context, realmResults, automaticUpdate);
}


@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder viewHolder;
    if (convertView == null) {
        convertView = inflater.inflate(android.R.layout.simple_list_item_1, parent, false);
        viewHolder = new ViewHolder();
        viewHolder.school = (TextView) convertView.findViewById(android.R.id.text1);
        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    School item = realmResults.get(position);
    viewHolder.school.setText(item.getSchoolName());
    return convertView;
}

public RealmResults<School> getRealmResults() {
    return realmResults;
}

}
.....

The following is my School class:

public class School extends RealmObject {

@Required
private String SchoolID;
private String SchoolName;
private RealmList<Student> Students;


public RealmList<Student> getStudents() {
    return Students;
   }

public void setStudents(RealmList<Student> students) {
    Students = students;
   }
}

My Student class as followed:

   public class Student extends RealmObject{

@Required
private String StudentID;
private String StudentName;

getters/setters
}

Our RealmBaseAdapter currently doesn't support RealmList (we have issue for it here: #1363), but you can e.g. convert a RealmList to a RealmResults by doing list.where().findAll(), or you can just use a normal ArrayAdapter (http://developer.android.com/reference/android/widget/ArrayAdapter.html) instead which should work as well.
