Hi, If you want activities to be talking to each other, one way of
achieving them is via encapsulating the data in the Place, as mentioned
above.
Imagine a complex application, where in a lot of objects are required by
different activities. In events like that, you have to pass on all the
required objects through Place(s). Which is kind of chain, where sometimes,
some values have to be passed just to enable the construction of all the
possible places/activities that could be triggered from there.
A simple solution on that case could be to have a singleton value store,
and use it for value types.
@Singleton
public class ValueStore {
private Map<String, Object> values = new HashMap<String, Object>();
public Object getValue(String key) {
return values.get(key);
}
public void putValue(String key, Object value) {
values.put(key, value);
}
public boolean hasValue(String key) {
return values.containsKey(key);
}
}
Such that the data populated in one activity could be consumed by a host of
other related activities.
Just another way of achieving the same!
