Syntax for creating a Object implementing Parcelable from getParcelableExtra(intent_name)

Question

I am implementing the DataDroid model of RESTful communication and I have come across a compiler error while implementing my SearchCriteria. The problem is that in order to pass the SearchCriteria around as an intent extra, I had to make it implement Parcelable. However, my Worker's start function requires a SearchCriteria class, leading to the error: Required: my.classes.SearchCriteria; Found: android.os.Parcelable.

Assuming that I've correctly implemented Parcelable for my SearchCriteria class, how can I quickly create an object from a parcel (where the parcel is found using getParcelable Extra(INTENT_NAME)?

Edit: I realize I can accomplish this quickly by making my constructor for SearchCriteria from Parcel public, but is there another way? Actually, this does not work - I confused a Parcel with a Parcelable thing.

Answer 1

Suppose you follow the API and make SearchCriteria implements Parcelable properly, and your SearchCriteria has been properly constructed or instantiated from the underlying business layer, either from a Database or a Http server or etc.

To pass it to next activity by intent:

SearchCriteria searchCriteria = createSearchCriteria();
Intent intent = new Intent(getBaseContext(), NextActivity.class);
intent.putExtra("searchCriteria", searchCriteria);
startActivity(intent);

To retrieve it from intent in next activity:

 SearchCriteria searchCriteria = getIntent().getParcelableExtra("searchCriteria");
 myWorker.search(searchCriteria);

In most situation, we don't need bother Parcel directly.
