Realm Array of Strings in Android - realm

Question

I have been trying to store an array of strings in Realm database programmatically as given below:
Model Class:
public class Station extends RealmObject {
private String name;
// ... Generated getters and setters ...
}
Saving Data:
realm.executeTransactionAsync(new Realm.Transaction() {
#Override
public void execute(Realm realm) {
Station station1 = realm.createObject(Station.class)
station1.setName(name1);
Station station2 = realm.createObject(Station.class)
station2.setName(name2);
//goes on till station8000
}
}, new Realm.Transaction.OnSuccess() {
#Override
public void onSuccess() {
// ...
});
Is there an alternate best way for this?

Answer 1

Why yes of course there is
public class Station extends RealmObject {
private String name;
// ... Generated getters and setters ...
}
and
// field variable
RealmResults<Station> stations;
// field variable
RealmChangeListener<RealmResults<Station>> changeListener = new RealmChangeListener<RealmResults<Station>>() {
#Override
public void onChange(RealmResults<Station> results) {
// handle onSuccess()
}
}
and
stations = realm.where(Station.class).findAll();
stations.addChangeListener(changeListener);
realm.executeTransactionAsync(new Realm.Transaction() {
#Override
public void execute(Realm realm) {
Station station = new Station();
for(String stationName : listOfStationNames) {
station.setName(stationName);
realm.insert(station);
}
}
});
EDIT: Check out this sexy spinner.
public class DropdownSpinnerAdapter
extends BaseAdapter
implements SpinnerAdapter {
private static final String TAG = "DropdownSpinnerAdapter";
private boolean isItemSelected;
RealmResults<Station> content;
public ResultDropdownSpinnerAdapter(RealmResults<Station> objects) {
this.content = objects;
}
#Override
public int getCount() {
if(content == null || !content.isValid()) {
return 1;
}
return content.size() + 1;
}
#Override
public String getItem(int position) {
if(position <= 0) {
return "";
}
return content.get(position - 1);
}
#Override
public long getItemId(int position) {
return position;
}
public int findPosition(Station selectedItem) {
for(int i = 0, s = content.size(); i < s; i++) {
Station item = content.get(i);
if(item.equals(selectedItem)) {
return i + 1;
}
}
return 0;
}
static class ViewHolder {
TextView textView;
ImageView imageView;
public ViewHolder(View convertView) {
textView = ButterKnife.findById(convertView, R.id.dropdown_textview);
imageView = ButterKnife.findById(convertView, R.id.dropdown_arrow);
}
}
#Override

}
if(convertView == null) {

parent,
false);
ViewHolder viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
}
ViewHolder viewHolder = (ViewHolder) convertView.getTag();
viewHolder.textView.setText(getItem(position).getName());
return convertView;
}
public void setItemSelected(boolean selected) {
this.isItemSelected = selected;
}
#Override

public void updateContent(RealmResults<Station> content) {
this.content = content;
notifyDataSetChanged();
