1、配置GreenDao插件

1*在主目录build.gradle配置插件路径

buildscript {
    repositories {
      jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'
    classpath 'org.greenrobot:greendao-gradle-plugin:3.2.1'

2*在工程目录运用插件并添加依赖

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'

3依赖

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
testCompile 'junit:junit:4.12'
compile 'org.greenrobot:greendao:3.2.0'
compile 'org.greenrobot:greendao-generator:3.2.0'

}

4*在工程目录android下添加greedao实体类转换自动生成路径

android {
compileSdkVersion 24
buildToolsVersion "25.0.0"

defaultConfig {
    applicationId "mobi.xiaowu.greendao"
    minSdkVersion 16
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

}
greendao{
    schemaVersion 1//版本
    targetGenDir 'src/main/java'
    daoPackage 'mobi.xiaowu.greendao.dao'
}

2.GreenDao使用

给实体类内容必须是基本类型，并且@Entity要声明在保存的数据类当中

@Id 主键关键字，可以设置autoincrement
@Transient 忽略该字段的关键字

写完注解后重新编译下即可在配置的目录下自动生成daoMaster、daoSession、daoXXX等实体类

 DaoMaster.DevOpenHelper helper = new DaoMaster.DevOpenHelper(this,"myDao.db");//通过自动生成的Master类开启Dao帮助类
    DaoMaster master = new DaoMaster(helper.getWritableDatabase());//开启数据库读取
    DaoSession daoSession = master.newSession();//使用自动生成的Session
    mDao = daoSession.getResultDao();//获取自动生成的dao实体类

mDao.insert(entity)；//存储实体类
Result load = mDao.load(mList.get(position).id);//获取实体类数据
