示例dao类如下,
public class DocumentRepository {
public static final String TABLE_DOCUMENT = "document";
public static final String COLUMN_ID = BaseColumns._ID;
public static final String RECORD_ID = "record_id";
public static final String UUID_DOCUMENT_NAME = "unique_file_name";
public static final String DOCUMENT_TABLE_CREATE = "create table if not exists "
+ TABLE_DOCUMENT + "(" + COLUMN_ID
+ " integer primary key autoincrement, " + RECORD_ID
+ " integer , " + UUID_DOCUMENT_NAME
+ " text );";
private Context context;
public DocumentRepository(Context context) {
this.context = context;
}
public ArrayList<Document> geDocuments(Integer customerId) {
ArrayList<Document> documents = new ArrayList<>();
String query = "SELECT * FROM " + TABLE_DOCUMENT + " WHERE " + RECORD_ID + " = '" + customerId + "'";
SQLiteDatabase database = ......// create a instance of your SqliteDatabase implementation
Cursor cursor = database.rawQuery(query, null);
if (cursor.moveToFirst()) {
do {
Document document = new Document();
document.setId(cursor.getInt(0));
document.setUniqueIdentifier(cursor.getString(3));
documents.add(document);
} while (cursor.moveToNext());
}
return documents;
}
}
geDocuments()
将为您提供对象列表。
