步骤如下：

1.配置项目的build.gradle文件

buildscript {    repositories {        jcenter()    }    dependencies {        classpath 'com.android.tools.build:gradle:2.3.3'        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}allprojects {    repositories {        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}

2.配置model的build.gradle文件

apply plugin: 'com.android.application'apply plugin: 'org.greenrobot.greendao'android {    compileSdkVersion 25    buildToolsVersion "25.0.2"    defaultConfig {        applicationId "net.sytm.demo"        minSdkVersion 15        targetSdkVersion 25        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    ///配置说明    ///1.配置项目的build.gradle    ///2.项目model的build.gradle    ///3.新建bean    greendao {        schemaVersion 1        daoPackage 'net.sytm.demo.greendao.gen'        targetGenDir 'src/main/java'    }}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-v7:25.3.1'    compile 'com.android.support.constraint:constraint-layout:1.0.1'    testCompile 'junit:junit:4.12'    compile 'org.greenrobot:greendao:3.2.2'    compile 'org.greenrobot:greendao-generator:3.2.2'}

3.新建bean

@Entitypublic class PersonInfoBean {    @Id    private int Id;    private String UserName;    private String PassWord;    private String RealName;    private String Mobile;}

4. 构建DAL层
操作：菜单栏 Build - Make Project

5.初始数据库

public class App extends Application {    private DaoSession daoSession;    @Override    public void onCreate() {        super.onCreate();        initGreenDao();    }    private void initGreenDao() {        DaoMaster.DevOpenHelper helper = new DaoMaster.DevOpenHelper(this, "info-db");        Database db = helper.getWritableDb();        daoSession = new DaoMaster(db).newSession();    }    public DaoSession getDaoSession() {        return daoSession;    }}

6.使用数据库

public class BaseActivity extends AppCompatActivity {    protected Activity activity;    protected Gson gson;    protected DaoSession daoSession;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        activity = this;        gson = new Gson();        daoSession = ((App) getApplication()).getDaoSession();    }}
