Automatically generate a ContentProvider backed by an SQLite database.
First create a class that contains the columns of a database table.
publicinterfaceListColumns{@DataType(INTEGER) @PrimaryKey@AutoIncrementString_ID = "_id"; @DataType(TEXT) @NotNullStringTITLE = "title"}Then create a database that uses this column
@Database(version = NotesDatabase.VERSION) publicfinalclassNotesDatabase{publicstaticfinalintVERSION = 1; @Table(ListColumns.class) publicstaticfinalStringLISTS = "lists"}And finally define a ContentProvider
@ContentProvider(authority = NotesProvider.AUTHORITY, database = NotesDatabase.class) publicfinalclassNotesProvider{publicstaticfinalStringAUTHORITY = "net.simonvt.schematic.sample.NotesProvider"; @TableEndpoint(table = NotesDatabase.LISTS) publicstaticclassLists{@ContentUri( path = "lists", type = "vnd.android.cursor.dir/list", defaultSort = ListColumns.TITLE + " ASC") publicstaticfinalUriLISTS = Uri.parse("content://" + AUTHORITY + "/lists")}@AutoIncrement@DataType@DefaultValue@NotNull@PrimaryKey@References@UniqueThe @ContentUri annotation is used when the Uri does not change.
@ContentUri( path = "lists", type = "vnd.android.cursor.dir/list", defaultSort = ListColumns.TITLE + " ASC") publicstaticfinalUriLISTS = Uri.parse("content://" + AUTHORITY + "/lists");If the Uri is created based on some value, e.g. an id, @InexactContentUri is used.
@InexactContentUri( path = Path.LISTS + "/#", name = "LIST_ID", type = "vnd.android.cursor.item/list", whereColumn = ListColumns._ID, pathSegment = 1) publicstaticUriwithId(longid){returnUri.parse("content://" + AUTHORITY + "/lists/" + id)}dependencies{annotationProcessor 'net.simonvt.schematic:schematic-compiler:{latest-version}' compile 'net.simonvt.schematic:schematic:{latest-version}' }Copyright 2014 Simon Vig Therkildsen Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
