IDE : AS 2.1.2
Module中build.gradle(修改):
compile ‘de.greenrobot:greendao-generator:1.3.1‘
产生dao:
public static void main(String[] args){
// 创建集合
Schema schema = new Schema(1,"jxj.wt.imqq.dao");
// 表的描述
Entity contactTable = schema.addEntity("QQContact");
contactTable.addIdProperty().primaryKey().autoincrement();
contactTable.addLongProperty("account");
contactTable.addStringProperty("nick");
contactTable.addIntProperty("avatar");
// 引擎
try {
new DaoGenerator().generateAll(schema, "../IMQQ/app/src/main/java");
} catch (Exception e) {
e.printStackTrace();
}
}
操作dao db:
public void test() {
QQContact contact01 = new QQContact();
contact01.setAccount(110L);
contact01.setNick("Tom");
contact01.setAvatar(1);
QQContact contact02 = new QQContact();
contact02.setAccount(120L);
contact02.setNick("Jack");
contact02.setAvatar(2);
SQLiteDatabase db = new DaoMaster.DevOpenHelper(mContext, "qq.db", null).getWritableDatabase();
// 获取DaoSession(集合)
DaoMaster master = new DaoMaster(db); // 指明哪个数据库的增删改查
DaoSession session = master.newSession();
// 开始操作
QQContactDao dao = session.getQQContactDao();
// 增加
dao.insert(contact01);
dao.insert(contact02);
// 修改
contact02.setNick("Lucy");
dao.update(contact02);
// 查询
List<QQContact> list = dao.loadAll();
for (QQContact item:list){
System.out.println(item.toString());
}
// 删除
dao.deleteByKey(2L);
}
查询结果:
