    作为一个开发者,数据的存储,用户的登陆,验证等操作,对程序来说是必不可少的,下面我们将从Bmob的基本信息开始讲起:

【Bmob】

  官网:   http://www.bmob.cn/

  帮助文档:http://www.bmob.cn/site/getdocs

  基本操作:http://docs.bmob.cn/android/faststart/index.html?menukey=fast_start&key=start_android

  SDK下载: http://www.bmob.cn/site/sdk

用户的基本操作

  Ⅰ用户注册:

  用户注册的表有两种,一种继承BmobUser,一种继承BmobObject,但是大部分作为用户的注册使用的一般是BmobUser

   JavaBean代码:

public class Students extends BmobUser {
    private int age;
    private String address;

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getAge() {

        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

  实现方法:

private void showRegist() {
        //用户注册的方法
        String userName=edt_user.getText().toString();
        String password=edt_password.getText().toString();
        Students stu=new Students();
        stu.setUsername(userName); //Username以及Password为Bmob中的User表,此表字段已经存在,故不可在javaBean中进行创建
        stu.setPassword(password);
        stu.setAge(21);
        stu.setEmail("linfanrong235@163.com"); //测试使用,邮箱验证的功能
        stu.setAddress("滨州");
        /*
         *用户注册的提交
         */
        stu.signUp(MainActivity.this,new SaveListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this,"注册成功",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this,"注册失败"+s,Toast.LENGTH_SHORT).show();
            }
        });
    }

Ⅱ用户登录:

private void showSubmit() {
        //用户登录的方法
        String userName=edt_user.getText().toString();
        String password=edt_password.getText().toString();
       final BmobUser user=new BmobUser();//创建对象,这个为Bmob创建的类
        //与数据库中的信息进行比对,成功返回成功,失败返回失败的信息
        user.setUsername(userName);
        user.setPassword(password);
        /*
         *用户登录
         */
        user.login(MainActivity.this,new SaveListener() {
            @Override
            public void onSuccess() {
                if(user.getEmailVerified())
                {
                    Toast.makeText(MainActivity.this,"登录成功",Toast.LENGTH_SHORT).show();
                }else{
                    //邮箱未验证
                }
            }

            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this,"登录失败"+s,Toast.LENGTH_SHORT).show();
            }
        });
    }
}

Ⅲ更新用户数据

private void showUpdate() {
        //用户更新的方法
        Students stu=BmobUser.getCurrentUser(MainActivity.this,Students.class);
        stu.setAddress("临沂");
        stu.setAge(25);
        stu.update(MainActivity.this,"5c8095e99b",new UpdateListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this,"更新成功",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this,"更新失败"+s,Toast.LENGTH_SHORT).show();
            }
        });
    }

Ⅳ修改密码

private void showRepassword() {
    //修改密码的方法
    final String email="876948462@qq.com";
    BmobUser.resetPassword(MainActivity.this,email,new ResetPasswordListener() {
        @Override
        public void onSuccess() {
            Toast.makeText(MainActivity.this,"修改密码,请到"+email,Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(int i, String s) {
            Toast.makeText(MainActivity.this,"重置密码失败",Toast.LENGTH_SHORT).show();
        }
    });
}

ps:此时系统会默认向你输入的邮箱发送修改密码的邮件

Ⅴ上传图片

private void submit() {
        //上传图片
        String path="sdcard/Download/shareone.jpg";
        final BmobFile file=new BmobFile(new File(path)); //创建BmobFile对象,转换为Bmob对象
        file.upload(MainActivity.this,new UploadFileListener() {
            @Override
            public void onSuccess() {
                share share=new share();
                share.setName("ShareOne");
                share.setAge(20);
                share.setIcon(file);  //设置图片
                share.save(MainActivity.this,new SaveListener() {
                    @Override
                    public void onSuccess() {
                        Toast.makeText(MainActivity.this,"上传成功",Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void onFailure(int i, String s) {
                        Toast.makeText(MainActivity.this,"上传失败"+s,Toast.LENGTH_LONG).show();

                    }
                });
            }

javaBean类:

public class share extends BmobObject {
    private String name;
    private int age;
    private BmobFile icon;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public BmobFile getIcon() {
        return icon;
    }

    public void setIcon(BmobFile icon) {
        this.icon = icon;
    }
}

【数据操作】

JavaBean类:

public class FootBaller extends BmobObject {
    private String name;
    private int age;
    private  int score;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getScore() {
        return score;
    }

    public void setScore(int score) {
        this.score = score;
    }
}

Ⅷ增加数据

private void showCreate() {
        FootBaller fb=new FootBaller();
        fb.setName("monster");
        fb.setAge(20);
        fb.setScore(100);
        fb.save(MainActivity.this,new SaveListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this,"创建成功",Toast.LENGTH_SHORT).show();
            }
            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this,"创建失败"+s,Toast.LENGTH_SHORT).show();
            }
        });
    }

Ⅸ更新数据

private void update() {
        FootBaller fb=new FootBaller();
        fb.setName("MonsterLin");
        fb.setScore(80);
        fb.setAge(26);
        fb.update(MainActivity.this, "ed8f8bdd14", new UpdateListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this, "更新成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this, "创建失败" + s, Toast.LENGTH_SHORT).show();
            }
        });
    }

Ⅹ删除数据

private void delete() {
        FootBaller fb=new FootBaller();
        fb.setObjectId("7a01c65384"); //删除对应的ObjectId
        fb.delete(MainActivity.this,new DeleteListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this, "删除成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(int i, String s) {
                Toast.makeText(MainActivity.this, "删除失败", Toast.LENGTH_SHORT).show();
            }
        });
    }

Ⅺ查询数据

        BmobQuery<FootBaller> query=new BmobQuery<FootBaller>();
        query.addWhereEqualTo("name","monster");
        query.findObjects(MainActivity.this,new FindListener<FootBaller>() {
            @Override
            public void onSuccess(List<FootBaller> footBallers) {
                for (FootBaller fb:footBallers)
                {
                    Toast.makeText(MainActivity.this, "查询数据成功"+fb.getName()+"---"+fb.getScore(), Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onError(int i, String s) {
                Toast.makeText(MainActivity.this, "查询失败"+s, Toast.LENGTH_SHORT).show();
            }
        });
    }

【邮箱验证】

邮箱验证参考【用户注册】板块,邮箱验证需要在你对应的Bmob下开启邮箱验证的服务

【小编有话说】

1.Bmob的初始化建议:

public class BaseActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        
        // 初始化BmobSDK
        Bmob.initialize(this, "Application ID");

然后书写的类继承BaseActivity

2.注意BmobUserBmobObject的使用:BmobUser的使用的时候,由于这张表作为系统表,所以已经存在的字段不允许自己重复定义,否则会出现编译不通过;BmobObject的表用户可以自定任意定义字段

3.在使用Bmob的使用需要加载SDK以及配置清单文件,具体操作:http://docs.bmob.cn/android/faststart/index.html?menukey=fast_start&key=start_android#index_%E5%AE%89%E8%A3%85BmobSDK

4.后续持续跟新…..
