整体功能展示
(1)对手机号码进行检测(中国大陆+港澳地区)和密码要求检测
(2)通过短信验证码进行账号注册
(3)账号和密码都保存到云端
(4)小眼睛(密码可见切换)
(5)获取验证码按钮60s冷却
创建应用
首先在Bmob注册自己的账号 https://www.bmob/ 注册账号就不一一教学了
然后打开我的控制台 → 创建应用,名称自己填写,类型看自己选择,我们选择开发版
创建好应用之后,打开刚刚创建的应用,在这里可以管理我们的应用
点击短信,选择自定义模板
模板名称
一定要填写,短信内容、签名我们使用默认的即可(有需要也可以自行修改)
保存之后等待审核,这个时间还是比较久的,大家耐心等待即可
配置Bmob
implementation 'io.github.bmob:android-sdk:3.8.2'
implementation "io.reactivex.rxjava2:rxjava:2.2.8"
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
implementation 'com.squareup.okhttp3:okhttp:3.14.1'
implementation 'com.squareup.okio:okio:2.2.2'
implementation 'com.google.code.gson:gson:2.8.5'

</provider>
复制上面代码到如图位置,并将图中小方形的代码修改为你自己的包名
Bmob的配置工作到这里就结束了,接下来就是敲代码了······
前期准备
一、数据表
首先我们创建一个类,类名自己取(到时候在自动Bmob后台会创建一个和类名一样的表),继承BmobObject类
package com.example.bmobloginservice;
import cn.bmob.v3.BmobObject;
public class User_Table extends BmobObject {
//账号
private String Account;
//密码
private String Password;
public String getAccount() {
return Account;
}
public void setAccount(String account) {
Account = account;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
}
表数据有Account
账号、Password
密码两个字段
二、工具类
新建一个Check类,创建两个方法用于号码检测(PhoneCheck)和密码检测(PasswordCheck)
-
号码检测
- 判断输入的收集号码是否满足国内号码的要求 密码检测
- 判断输入的密码是否满足要求(最少有3个字母)
package com.example.bmobloginservice;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Check {
/**
* 手机号码检测
* @param phone:输入的号码
* @return true -->>号码正确,false-->>号码不正确
*/
public static boolean PhoneCheck(String phone){
String ChineseMainland = "^((13[0-9])|(14[5,7,9])|(15[0-3,5-9])|(166)|(17[3,5,6,7,8])" + "|(18[0-9])|(19[8,9]))\\d{8}$";
String HongKong = "^(5|6|8|9)\\d{7}$";
Matcher C = Pattern.compile(ChineseMainland).matcher(phone);
Matcher H = Pattern.compile(HongKong).matcher(phone);
return C.matches() || H.matches();
}
/**
* 密码检测(是否符合最少3个字母的要求)
* @param password:输入的密码
* @return true-->>密码格式正确,false-->>密码格式不正确
*/
public static boolean PasswordCheck(String password){
char[] s = password.toCharArray();
int count=0;
for (int i = 0; i < s.length; i++) {
if ((s[i]>='a'&&s[i]<='z') || (s[i]>='A'&&s[i]<='Z')){
count++;
}
}
if (count>=3){
return true;
}else {
return false;
}
}
}

最后运行测试效果,已成功注册到账号,并保存到Bmob后端云中
四、注意事项
自定义模板一定要等审核成功才能使用,不然会闪退报错
将代码中的appley
里的字符串换成自己Bmob后端云的Application ID
