Curson
Cursor binding which uses annotation processing to generate boilerplate code for you.
- Eliminate
getColumnIndexcalls by using@CursorRowon fields.
How to use
Create Entity class
You have to create a entity class like below.
class Item {
@CursorRow("_id"/*CURSOR_COLUMN_NAME*/)
int id;
@CursorRow("MEMO")
String memo;
@CursorRow("DATE")
long date;
}CursorRow annotations supports
- byte[]
- int / Integer
- double / Double
- float / Float
- short / Short
- String
Convert to entity/cursor
To Entity
public Item getItem() {
Cursor cursor = context.getContentResolver().query(
ExContentProvider.Contract.MEMO_URI,
null,
MemoColumns.MEMO_ID + " = ?",
new String[]{dataSnapshot.getKey()}, null);
return Curson.fromCursor(cursor, Item.class, 0);
}
public List<Item> getItems() {
Cursor cursor = context.getContentResolver().query(
ExContentProvider.Contract.MEMO_URI,
null, null, null, null);
return Curson.fromCursor(cursor, Item.class);
}To Cursor
public Cursor toCursor() {
Item item = new Item();
item.id = 1;
item.memo = "Hello Curson!!";
item.date = 1L;
return Curson.toCursor(item, Item.class);
}
public Cursor toCursor() {
List<Item> items = new ArrayList<>();
Item item = new Item();
item.id = 1;
item.memo = "Hello Curson!!";
item.date = 1L;
items.add(item);
return Curson.toCursor(items, Item.class);
