project_build.grade：

buildscript {
    repositories {
        jcenter()
        mavenCentral() // add repository
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        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
    }
}

model_build.grade:

apply plugin: 'org.greenrobot.greendao'

greendao {
    schemaVersion 1
    daoPackage 'com.anye.greendao.gen'
    targetGenDir 'src/main/java'
}

compile'org.greenrobot:greendao:3.0.1'
compile'org.greenrobot:greendao-generator:3.0.0'

先建一個User類：

@Entity(nameInDb = "YueDb")
public class User {
    @Id
    private Long id;
    private String name;

}

然後在菜單欄build裏點擊make mondle "app"

MvApplication:

public class Mvapplication extends Application {

    private DaoSession daoSession;

    @Override
    public void onCreate() {
        super.onCreate();
        DaoMaster.DevOpenHelper mHelper = new DaoMaster.DevOpenHelper(this, "notes-db", null);
        SQLiteDatabase database = mHelper.getWritableDatabase();
        DaoMaster daoMaster = new DaoMaster(database);
        daoSession = daoMaster.newSession();
    }

    public DaoSession getDaoSession() {
        return daoSession;
    }
}

MainActivity :

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private UserDao userDao;
    private Button zeng;
    private Button shan;
    private Button xiu;
    private Button cha;
    private ListView listView;
    private List<User> list;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        DaoSession daoSession = ((Mvapplication) getApplicationContext()).getDaoSession();
        userDao = daoSession.getUserDao();
        initView();
    }

    private void initView() {
        zeng = (Button) findViewById(R.id.zeng);
        shan = (Button) findViewById(R.id.shan);
        xiu = (Button) findViewById(R.id.xiu);
        cha = (Button) findViewById(R.id.cha);
        listView = (ListView) findViewById(R.id.listView);
        zeng.setOnClickListener(this);
        shan.setOnClickListener(this);
        xiu.setOnClickListener(this);
        cha.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.zeng:
                for (int i = 1; i < 10; i++) {
                    User user = new User();
                    user.setName("嶽俊飛" + i);
                    userDao.insert(user);
                }
                break;
            case R.id.shan:
                userDao.deleteByKey((long) 3);
                break;
            case R.id.xiu:
                User user1 = new User((long) 5, "嶽小蛋");
                userDao.update(user1);
                break;
            case R.id.cha:
                list = userDao.loadAll();
                Mydapter mydapter = new Mydapter();
                listView.setAdapter(mydapter);
                break;
        }
    }

    class Mydapter extends BaseAdapter {


        @Override
        public int getCount() {
            return list == null ? 0 : list.size();
        }

        @Override
        public Object getItem(int position) {
            return list.get(position);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            Holder holder;
            if (convertView==null){
                convertView=convertView.inflate(MainActivity.this,R.layout.item_main,null);
                holder = new Holder();
