GreenDao

1.在自己项目的build里面导入依赖

①:apply plugin: 'org.greenrobot.greendao'

②:android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.liu.liupengfa20181210"
        minSdkVersion 18
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    greendao {
        schemaVersion 1  //版本
        daoPackage 'com.liu.liupengfa20181210.greendao' // 一般为app包名+生成文件的文件夹名
        targetGenDir 'src/main/java' //生成文件路径
    }
}

③:implementation 'org.greenrobot:greendao:3.0.1'
    implementation 'org.greenrobot:greendao-generator:3.0.0'

2.在大项目中导入依赖

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    
    repositories {
        google()
        jcenter()
        //中心仓库
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
 

3.build中 make

4.在App中初始化

DaoMaster.DevOpenHelper helper = new DaoMaster.DevOpenHelper(this, "abw.db", null);
SQLiteDatabase writableDatabase = helper.getWritableDatabase();
DaoMaster daoMaster = new DaoMaster(writableDatabase);
daoSession = daoMaster.newSession();

5.在成功的方法中添加数据库

//初始化
gDaoDao = App.daoSession.getGDaoDao();
//存入数据库
ArrayList<GDao> greenDaos = new ArrayList<>();
for (int i = 0; i < list.size(); i++) {
    List<Entity.DataBean.ListBean> listBean = this.list.get(i).getList();
    for (int j = 0; j < listBean.size(); j++) {
        String title = listBean.get(j).getTitle();
        int price = listBean.get(j).getPrice();
        greenDaos.add(new GDao(title, String.valueOf(price)));
    }
}
for (int i = 0; i < greenDaos.size(); i++) {
    gDaoDao.insert(greenDaos.get(i));
}
