- 配置
- 初始化
- 建立数据库和表
- 增删改查
1.1 在项目build.gradle添加apt插件和库
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
maven { url "https://www.jitpack.io" }
1.2 在app的build.gradle中配置
apply plugin: 'com.neenbedankt.android-apt'
def dbflow_version = "3.1.1"
apt "com.github.Raizlabs.DBFlow:dbflow-processor:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow-core:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow:${dbflow_version}"
FlowManager.init(new FlowConfig.Builder(getApplicationContext()).build());
3.1 新建AppDatabase类,配置表数据库名称和版本
@Database(name = AppDatabase.NAME, version = AppDatabase.VERSION)
public class AppDatabase {
//数据库名
public static final String NAME = "DBFlow_DB";
//数据库版本
public static final int VERSION = 1;
}
3.2 新建User表,继承实体基类BaseModel
@Table(database = AppDatabase.class)
public class User extends BaseModel {
//设置主键,并自动增长,从1开始
@PrimaryKey(autoincrement = true)
private long tableId;
@Column
private String name;
@Column
private int age;
public User() {
super();
}
public long getTableId() {
return tableId;
}
public void setTableId(long tableId) {
this.tableId = tableId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
4.1 增加
User user = new User();
user.setName("张三");
user.setAge(18);
user.save();
4.2 删除
User user = new User();
user.setTableId(1);
user.delete();
4.3 更新
User user = new User();
user.setName("李四");
user.setTableId(1);
user.update();
4.4 查询
List<User> userList = SQLite.select().from(User.class).where(User_Table.name.eq("张三")).queryList();
