1.配置项目下的build
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath ("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.0")
classpath ("org.greenrobot:greendao-gradle-plugin:3.3.1") // 使用最新版本
}
}
2.配置app下的build
id("org.jetbrains.kotlin.kapt")
id("org.greenrobot.greendao")
kapt {
arguments {
arg("daoPackage", "你的ApplicatinId")
arg("databaseName", "你的数据库名称-db")
arg("targetGenDir", "/src/main/java")
arg("schemaVersion", "1")
}
}
implementation("org.greenrobot:greendao:3.2.2")
kapt("org.greenrobot:greendao-generator:3.2.2")
3.初始化数据库
class App : Application() {
private var myOpenHelper: MyOpenHelper? = null
private var db: SQLiteDatabase? = null
private var mDaoMaster: DaoMaster? = null
private var mDaoSession: DaoSession? = null
override fun onCreate() {
super.onCreate()
setDatabase()
}
private fun setDatabase() {
myOpenHelper = MyOpenHelper(this, "你的数据库名称-db", null)
db = myOpenHelper!!.writableDatabase
mDaoMaster = DaoMaster(db)
mDaoSession = mDaoMaster!!.newSession()
}
fun getmDaoSession(): DaoSession? {
mDaoSession = mDaoMaster!!.newSession()
return mDaoSession
}
inner class MyOpenHelper(context: Context?, name: String?, factory: CursorFactory?) :
DaoMaster.OpenHelper(context, name, factory)
}
4.实体类
@Entity
public class TypeEntity {
@Id(autoincrement = true)
private Long id;
private int color;
private String type;
}
5.实例类写好之后锤子🔨锤一下就自动生成后续代码了 【快捷键忘了,如果有记得的同学,欢迎留言Thanks♪(・ω・)ノ 】。
