Class RealmBaseAdapter<T extends RealmObject>

java.lang.Object

android.widget.BaseAdapter

io.realm.RealmBaseAdapter<T>

All Implemented Interfaces:

android.widget.Adapter, android.widget.ListAdapter, android.widget.SpinnerAdapter

public abstract class RealmBaseAdapter<T extends RealmObject>
extends android.widget.BaseAdapter

The RealmBaseAdapter class is an abstract utility class for binding UI elements to Realm data, much like an CursorAdapter.

This adapter will automatically handle any updates to its data and call BaseAdapter.notifyDataSetChanged() as appropriate.

The RealmAdapter will stop receiving updates if the Realm instance providing the RealmResults is closed. Trying to access read objects, will at this point also result in a RealmException.

Constructor Detail

RealmBaseAdapter

public RealmBaseAdapter(android.content.Context context,
                        RealmResults<T> realmResults,
                        boolean automaticUpdate)

Method Detail

getCount

public int getCount()

getItem

public T getItem(int i)

getItemId

public long getItemId(int i)

Returns the current ID for an item. Note that item IDs are not stable so you cannot rely on the item ID being the same after BaseAdapter.notifyDataSetChanged() or updateRealmResults(RealmResults) has been called.

Parameters:

i - Index of item in the adapter

Returns:

Current item ID.

updateRealmResults

public void updateRealmResults(RealmResults<T> queryResults)

Update the RealmResults associated to the Adapter. Useful when the query has been changed. If the query does not change you might consider using the automaticUpdate feature

Parameters:

queryResults - the new RealmResults coming from the new query.
