开发一个好项目：三、创建数据源，首先创建本地数据源

前一篇文章：开发一个好项目：二、actvity简便跳转，创建菜单按钮，正确使用fragment 框架地址dileber android框架 希望大家能多多star一下

创建数据模型LaunchModel

public class LaunchModel extends SModel {    UserInfoModel userInfoModel;    public UserInfoModel getUserInfoModel() {        return userInfoModel;    }    public void setUserInfoModel(UserInfoModel userInfoModel) {        this.userInfoModel = userInfoModel;    }}

UserInfoModel 有一个_id ,主要是用于数据库添加自增长的id，继承于smodel，可以更好的做数据处理，比如在插入数据，或者本地数据存储，框架里都做了处理

public class UserInfoModel extends SModel {    private Integer _id;    public Integer get_id() {        return _id;    }    public void set_id(Integer _id) {        this._id = _id;    }    private Integer userinfoid;    private Integer uid;    private String userinfoname;    private Integer userinfoheight;    private Integer userinfoweight;    private Integer userinfoclub;    private Integer userinfohand;    private Integer userinfobackhand;    private Integer userinfofloor;    private String userinfohandname;    private String userinfobackhandname;    private String userinfofloorname;    private String userinfoflag;    private Integer userinfogender;    private Date userinfobirthday;    private Integer userinfolocal;    private String userinfolocalname;    private String userinfointroduce;    private String userinfoskill;    private String usernikename;    private String userphone;    private String userimage;    private Integer userimageversion;    private Integer userinfofenshu;    public Integer getUserinfofenshu() {        return userinfofenshu;    }    public void setUserinfofenshu(Integer userinfofenshu) {        this.userinfofenshu = userinfofenshu;    }    public String getUserphone() {        return userphone;    }    public void setUserphone(String userphone) {        this.userphone = userphone;    }    public String getUserimage() {        return userimage;    }    public void setUserimage(String userimage) {        this.userimage = userimage;    }    public Integer getUserimageversion() {        return userimageversion;    }    public void setUserimageversion(Integer userimageversion) {        this.userimageversion = userimageversion;    }    public String getUsernikename() {        return usernikename;    }    public void setUsernikename(String usernikename) {        this.usernikename = usernikename;    }    public String getUserinfoskill() {        return userinfoskill;    }    public void setUserinfoskill(String userinfoskill) {        this.userinfoskill = userinfoskill == null ? null : userinfoskill.trim();    }    public Integer getUserinfoid() {        return userinfoid;    }    public void setUserinfoid(Integer userinfoid) {        this.userinfoid = userinfoid;    }    public Integer getUid() {        return uid;    }    public void setUid(Integer uid) {        this.uid = uid;    }    public String getUserinfoname() {        return userinfoname;    }    public void setUserinfoname(String userinfoname) {        this.userinfoname = userinfoname == null ? null : userinfoname.trim();    }    public Integer getUserinfoheight() {        return userinfoheight;    }    public void setUserinfoheight(Integer userinfoheight) {        this.userinfoheight = userinfoheight;    }    public Integer getUserinfoweight() {        return userinfoweight;    }    public void setUserinfoweight(Integer userinfoweight) {        this.userinfoweight = userinfoweight;    }    public Integer getUserinfoclub() {        return userinfoclub;    }    public void setUserinfoclub(Integer userinfoclub) {        this.userinfoclub = userinfoclub;    }    public Integer getUserinfohand() {        return userinfohand;    }    public void setUserinfohand(Integer userinfohand) {        this.userinfohand = userinfohand;    }    public Integer getUserinfobackhand() {        return userinfobackhand;    }    public void setUserinfobackhand(Integer userinfobackhand) {        this.userinfobackhand = userinfobackhand;    }    public Integer getUserinfofloor() {        return userinfofloor;    }    public void setUserinfofloor(Integer userinfofloor) {        this.userinfofloor = userinfofloor;    }    public String getUserinfohandname() {        return userinfohandname;    }    public void setUserinfohandname(String userinfohandname) {        this.userinfohandname = userinfohandname == null ? null : userinfohandname.trim();    }    public String getUserinfobackhandname() {        return userinfobackhandname;    }    public void setUserinfobackhandname(String userinfobackhandname) {        this.userinfobackhandname = userinfobackhandname == null ? null : userinfobackhandname.trim();    }    public String getUserinfofloorname() {        return userinfofloorname;    }    public void setUserinfofloorname(String userinfofloorname) {        this.userinfofloorname = userinfofloorname == null ? null : userinfofloorname.trim();    }    public String getUserinfoflag() {        return userinfoflag;    }    public void setUserinfoflag(String userinfoflag) {        this.userinfoflag = userinfoflag == null ? null : userinfoflag.trim();    }    public Integer getUserinfogender() {        return userinfogender;    }    public void setUserinfogender(Integer userinfogender) {        this.userinfogender = userinfogender;    }    public Date getUserinfobirthday() {        return userinfobirthday;    }    public void setUserinfobirthday(Date userinfobirthday) {        this.userinfobirthday = userinfobirthday;    }    public Integer getUserinfolocal() {        return userinfolocal;    }    public void setUserinfolocal(Integer userinfolocal) {        this.userinfolocal = userinfolocal;    }    public String getUserinfolocalname() {        return userinfolocalname;    }    public void setUserinfolocalname(String userinfolocalname) {        this.userinfolocalname = userinfolocalname == null ? null : userinfolocalname.trim();    }    public String getUserinfointroduce() {        return userinfointroduce;    }    public void setUserinfointroduce(String userinfointroduce) {        this.userinfointroduce = userinfointroduce == null ? null : userinfointroduce.trim();    }}

创建接口SysDataSource 继承基类BaseDataSource 里面全是是获取数据的接口

public interface SysDataSource extends BaseDataSource{    void getLaunch(BaseDataSource.BaseCallback<LaunchModel> callback);}

创建本地数据处理类SysLocalDataSource 数据类里直接就有数据库处理方式，只需要写好数据库创建语句，之后添加到list，用dbmanager就可以使用数据库的方法了，数据库方法很多，有批量插入，批量更新。单次增删查改。也可以直接映射到model上，只要你继承smodel！

public class SysLocalDataSource extends BaseLocalDataSource implements SysDataSource{    String match = "CREATE TABLE match (_id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,matchid INTEGER,matchname TEXT,matchtime INTEGER,matchcreatetime INTEGER,matchfromuser INTEGER,matchtouser INTEGER,matchstate INTEGER,matchplace INTEGER)";    private static volatile SysLocalDataSource instance;    private SysLocalDataSource(){        List<String> list = new ArrayList<>();        list.add(match);        dbManager = dbManager.getDB("launch",Config.DB_VERSION,list);    }    public static SysLocalDataSource getInstance(){        if (instance==null){            synchronized (SysLocalDataSource.class){                if(instance==null){                    instance = new SysLocalDataSource();                }            }        }        return instance;    } @Override    public void getLaunch(BaseDataSource.BaseCallback<LaunchModel> callback) {        String launch = hPref.get(Config.PERF_APP,Config.PERF_LANUCH,null,String.class);        Logger.sl(Log.DEBUG,launch);        if(launch!=null){            callback.onSuccess(HJson.fromJson(launch,LaunchModel.class));        }else{            callback.onFailure(new DataSourceException("数据为空"));        }    }}

这个类怎么使用后续会继续讲解，后续还有如何使用缓存使得数据源快速加载。等等~~~~
