Here is a sample of the JSON I am trying to read:
{"version":1,"recipe":[{"id":"1","title":"Nastia's Roasted Unstuffed
Turkey","description":"As a foreign exchange student, I was invited
for Thanksgivings and Christmas dinners by more than 20 different
American
families","skill":"Intermediate","nationality":"American","dishtype":"Main
Course","servings":"6","author":"bhsmith","created_at":"2008-11-06
00:18:52","ingredients":["ingr 1","ingr 2","ingr 3"]}]}
** consider that ingredients can have a variable number of items in
the array
Here is the code I am working with:
----------------
final RecordDef recordDef = new RecordDef(new FieldDef[]{
new IntegerFieldDef("id"),
new StringFieldDef("title"),
new StringFieldDef("description"),
new StringFieldDef("skill"),
new StringFieldDef("nationality"),
new StringFieldDef("dishtype"),
new IntegerFieldDef("servings"),
new StringFieldDef("author"),
new DateFieldDef("created_at", "created_at",
"timestamp")
?????????????????????????
});
JsonReader reader = new JsonReader(recordDef);
reader.setRoot("recipe");
// reader.setId("id");
DataProxy dataProxy = new ScriptTagProxy("http://localhost/
test_feed/getrecipe.php");
final Store store = new Store(dataProxy, reader, false);
----------------
I put ? marks where I need to put something I am just not sure what.
What type of FieldDef can I use to describe the JSON object that is
actually an array of strings?
Thanks.
