1. 添加依赖

  //数据库框架
    compile 'com.j256.ormlite:ormlite-android:5.0'

2. 编写OpenHelper

Openhelper的作用是指定数据库名称，版本，与表

public class MyHelper extends OrmLiteSqliteOpenHelper{
    private static final String databaseName="xxxxx.db";
    private static final SQLiteDatabase.CursorFactory factory=null;
    private static final int databaseVersion=1;

    public MyHelper(Context context) {
        super(context, databaseName, factory, databaseVersion);
    }

    @Override
    public void onCreate(SQLiteDatabase database, ConnectionSource connectionSource) {

        //ORM数据框架 依赖 orm 对象关系映射关系
        try {
            TableUtils.createTable(connectionSource,ReceiptAddredsInfo.class);
            TableUtils.createTable(connectionSource,AllUserInfo.class);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onUpgrade(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion) {

    }
}

3. 编写带有映射关系的javaBean

//1.无参构造函数
//2.get/set
//3.配置表名
//4.配置表字段

@DatabaseTable(tableName = "t_receipt_address")
public class ReceipAddressInfo implements Serializable{
    //主键 id自增长
    @DatabaseField(columnName = "_id",generatedId = true)
    private int id;
    //用户id
    @DatabaseField(columnName = "uid")
    private String uid;
    @DatabaseField(columnName = "name")
    private String name;
    @DatabaseField(columnName = "sex")
    private String sex;
    @DatabaseField(columnName = "phone")
    private String phone;
    @DatabaseField(columnName = "otherPhone")
    private String otherPhone;
    @DatabaseField(columnName = "receiptAddress")
    private String receiptAddress;
    @DatabaseField(columnName = "detailAddress")
    private String detailAddress;
    @DatabaseField(columnName = "lable")
    private String lable;


    public ReceipAddressInfo() {
    }
}

4. 获取dao

//                        MyHelper myHelper = new MyHelper(context);
//                        try {
//                            dao = myHelper.getDao(AllUserInfo.class);
//                        } catch (SQLException e) {
//                            e.printStackTrace();
//                        }

5. 针对数据库的操作 增删改查

                       dao.create();
                        dao.delete();
                        dao.update();
                        dao.queryForAll();
