WeDoxDB_demo

Sqlite数据库操作框架WeDoXDB

How to use?

Step 0.Add it in your root build.gradle at the end of repositories:

allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Step 1. Add the dependency

dependencies {
	        implementation 'com.github.WeDox:WeDoxDB_demo:1.0.1'
	}

Step 2.to use

使用指南

1、创建Bean类（必须要有无参构造方法、有主键、主键也需要加上 @Column）

public class CatBean {
    @PrimaryKey
    @Column
    private int id;
    @Column
    private String name;
    @Column
    private int age;
    //新增地址字段
    @Column
    private String address;
    @Column
    private int height;



    public CatBean() {
    }
    。。。。。
 }

2、配置数据库信息

2_1、创建配置类

public class DbConfig extends BaseWeDoXDBConfig {
   private static final String DB_NAME = "wedox_db_test.db";
   private static final int DB_VERSION = 10;//TODO 每次新增表或者表的结构改变时，自增1，并在onUpgrade方法内做对应的操作
   private static final List<Class<?>> DB_ENTITIES;

   static {
       DB_ENTITIES = new ArrayList<Class<?>>();
       DB_ENTITIES.add(CatBean.class);
   }

   @Override
   public String providerDbName() {
       return DB_NAME;
   }

   @Override
   public int providerCurrentDbVersion() {
       return DB_VERSION;
   }

   @Override
   public List<Class<?>> providerTableNameListData() {
       return DB_ENTITIES;
   }

   @Override
   public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
       Log.e("ATU", "版本更新===》当前数据库版本为：" + newVersion + "===之前的版本为:" + oldVersion);
       //版本8新增一个地址字段
       if (newVersion >= 8 && oldVersion < 8) { //
           WeDoXDBOperatorHelper.addStringColumn(db, CatBean.class, "address", "默认产地");
       }
       //版本10新增一个身高字段
       if (newVersion >= 10 && oldVersion < 10) {
           WeDoXDBOperatorHelper.addIntColumn(db, CatBean.class, "height");
       }
   }
}

2_2、全局设置数据库配置类

在自定义的Application中初始化

public class AppApplication  extends Application {

  @Override
  public void onCreate() {
      super.onCreate();
      //初始化WeDoxDB数据库配置
      WeDoxDBConfigManager.init(new DbConfig());
  }
}

3、创建数据表操作类

public class CatBeanDao extends BaseDbDao<CatBean> {

   @Override
   public Class<CatBean> getType() {
       return CatBean.class;
   }
}

4、具体使用

  CatBeanDao catBeanDao = new CatBeanDao();
        List<CatBean> catBeanList = new ArrayList<>();
        CatBean catBean = new CatBean();
        catBean.setId(1);
        catBean.setAge(2009);
        catBean.setName("小红2009");
        catBeanList.add(catBean);
        long result = catBeanDao.upsert(this, catBeanList);
        Log.e("ATU", "结果为：" + result);
        List<CatBean> resultList = catBeanDao.querry(this, null, null, null);
        //
        String info = "";
        for (CatBean tempCat : resultList) {
            Log.e("ATU", "结果为：" + tempCat);
            info += tempCat.toString();
        }
