前言

        本项目尚在开发阶段，主要针对的是安卓用户，通过查阅开发文档以及借鉴其他博主，由于是个人开发，可能会在逻辑会有所缺漏，欢迎各位安卓使用者与开发者进行内测并提交反馈意见给我，进行探讨顺便带带我；

        本项目开发主题尚未决定，故本期向各位征集意见，可以通过安装该app进行注册登录，并写下您的想法提交反馈给我，后续将对收集的idea进行整合并决定方向，进行下一步的开发。

        ps:保证无病毒与无信息泄露！！！欢迎大家参与

概览

        本期主要用到两个工具，Android Studio和Bmob后端云（后续介绍），在安卓客户端注册登陆并提交想法，最终在Bmob后端云中实现数据可视化，主要实现效果如下图所示

  • Android Studio

  • Bmob后端云

         Android Studio在此不做介绍了，以下是对Bmob后端云的介绍

Bmob后端云介绍

        本次采用Bmob后端云（Bmob后端云 (bmobapp.com)）主要是其集成了数据库与服务器，对于很多Android/ios/wp个人移动开发者来说，开发一个具有网络功能的应用不是一件容易的事，不仅需要购买/租赁服务器，还必须掌握一门诸如Java/.net/php这类的服务器开发语言，每开发一款移动应用程序，就必须开发维护对应的服务器程序，鉴于此我目前水平有限，故先采用Bmob后端云进行开发，给应用软件快速添加一个安全灵活的后台管理系统，方便浏览终端保存的各种信息。

Bmob后端云与Android Studio配置

一、Bmob后端云

  • 创建应用

  • 创建表单，默认有一个_User表单（不用管），要新建一个User表单（名称要与后边安卓代码相同），数据将会在这个表单呈现

  •  获取key秘钥，后边需要用

 二、Android Studio配置

  •  AndroidManifest.xml:

        1、添加网络权限

        在上图位置添加下方代码以添加网络权限

  1. <!--允许联网 -->
  2. <uses-permission android:name="android.permission.INTERNET" />
  3. <!--获取GSM（2g）、WCDMA（联通3g）等网络状态的信息  -->
  4. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  5. <!--获取wifi网络状态的信息 -->
  6. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
  7. <!--保持CPU 运转，屏幕和键盘灯有可能是关闭的,用于文件上传和下载 -->
  8. <uses-permission android:name="android.permission.WAKE_LOCK" />
  9. <!--获取sd卡写的权限，用于文件上传和下载-->
  10. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  11. <!--允许读取手机状态 用于创建BmobInstallation-->
  12. <uses-permission android:name="android.permission.READ_PHONE_STATE" />

        2、连接Bmob

         在上图位置添加下方代码，并将蓝色方框中的代码替换成红色箭头所指的自己代码的包名

  1. <provider
  2.     android:name="cn.bmob.v3.util.BmobContentProvider"
  3.     android:authorities="包名.BmobContentProvider">
  4. </provider>
  •  在Activity中对Bmob进行初始化，在OnCreat方法中添加下方代码并将你的应用ID替换成上方Bmob配置时获取的key密钥

Bmob.initialize(this,"你的应用ID");
  • 在build.gradle(Module:app)中添加包

  1. implementation 'io.github.bmob:android-sdk:3.9.4'
  2. implementation 'io.reactivex.rxjava2:rxjava:2.2.8'
  3. implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
  4. implementation 'com.squareup.okhttp3:okhttp:4.8.1'
  5. implementation 'com.squareup.okio:okio:2.2.2'
  6. implementation 'com.google.code.gson:gson:2.8.5'

        至此，配置已全部完成，接下来是进行界面设计与逻辑代码编写环节

工具类

一、User类

        这个工具类的名称与前边在Bmob创建的表单名称相同，这个类继承于BmobObject，其属性相当于在表中的数据。

  1. package com.example.application.tool;
  2.  
  3. import java.io.Serializable;
  4.  
  5. import cn.bmob.v3.BmobObject;
  6.  
  7. public class User extends BmobObject implements Serializable {
  8.     private String Acctount;//手机账户
  9.     private String Password;//密码
  10.     private String Context;//反馈内容
  11.  
  12.     public String getAcctount() {
  13.         return Acctount;
  14.     }
  15.  
  16.     public void setAcctount(String acctount) {
  17.         Acctount = acctount;
  18.     }
  19.  
  20.     public String getPassword() {
  21.         return Password;
  22.     }
  23.  
  24.     public void setPassword(String password) {
  25.         Password = password;
  26.     }
  27.  
  28.     public String getContext() {
  29.         return Context;
  30.     }
  31.  
  32.     public void setContext(String context) {
  33.         Context = context;
  34.     }
  35. }

二、Suit类

        这个类主要是号码检测（是否符合格式）与密码检测（至少包含3个字母）

  1. package com.example.application.tool;
  2.  
  3. import java.util.regex.Matcher;
  4. import java.util.regex.Pattern;
  5.  
  6. public class Suit {
  7.     //手机号码检测
  8.     public static boolean PhoneSuit(String phone){
  9.         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}$";
  10.         String HongKong = "^(5|6|8|9)\\d{7}$";
  11.  
  12.         Matcher C = Pattern.compile(ChineseMainland).matcher(phone);
  13.         Matcher H = Pattern.compile(HongKong).matcher(phone);
  14.         return C.matches() || H.matches();
  15.     }
  16.  
  17.     //密码检测（最少3个字母）
  18.     public static boolean PasswordSuit(String password){
  19.         char[] s = password.toCharArray();
  20.         int count = 0 ;
  21.         //检测所有的密码中有多少个字母
  22.         for (int i = 0;i < s.length;i++){
  23.             if ((s[i] >= 'a' && s[i] <= 'z') || (s[i] >= 'A' && s[i] <= 'Z')){
  24.                 count++;
  25.             }
  26.         }
  27.         if (count >= 3){
  28.             return true;
  29.         }else {
  30.             return false;
  31.         }
  32.     }
  33. }

三、Code类

        这个类主要是生成验证码图片，由于目前短信验证在资源上有数量限制，故采用验证码图片进行验证，在实现类中通过创建类对象调用类方法实现对验证码图片的生成。

  1. package com.example.application.tool;
  2.  
  3. import android.graphics.Bitmap;
  4. import android.graphics.Canvas;
  5. import android.graphics.Color;
  6. import android.graphics.Paint;
  7.  
  8. import java.util.Random;
  9.  
  10. public class Code {
  11.  
  12.     //随机数数组
  13.     private static final char[] CHARS = {
  14.             '2', '3', '4', '5', '6', '7', '8', '9',
  15.             'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'j', 'k', 'm',
  16.             'n', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z',
  17.             'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M',
  18.             'N', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'
  19.     };
  20.  
  21.     private static Code bmpCode;
  22.  
  23.     public static Code getInstance() {
  24.         if(bmpCode == null)
  25.             bmpCode = new Code();
  26.         return bmpCode;
  27.     }
  28.  
  29.     //default settings
  30.     //验证码默认随机数的个数
  31.     private static final int DEFAULT_CODE_LENGTH = 4;
  32.     //默认字体大小
  33.     private static final int DEFAULT_FONT_SIZE = 25;
  34.     //默认线条的条数
  35.     private static final int DEFAULT_LINE_NUMBER = 5;
  36.     //padding值
  37.     private static final int BASE_PADDING_LEFT = 10, RANGE_PADDING_LEFT = 15, BASE_PADDING_TOP = 15, RANGE_PADDING_TOP = 20;
  38.     //验证码的默认宽高
  39.     private static final int DEFAULT_WIDTH = 100, DEFAULT_HEIGHT = 40;
  40.  
  41.     //settings decided by the layout xml
  42.     //canvas width and height
  43.     private int width = DEFAULT_WIDTH, height = DEFAULT_HEIGHT;
  44.  
  45.     //random word space and pading_top
  46.     private int base_padding_left = BASE_PADDING_LEFT, range_padding_left = RANGE_PADDING_LEFT,
  47.             base_padding_top = BASE_PADDING_TOP, range_padding_top = RANGE_PADDING_TOP;
  48.  
  49.     //number of chars, lines; font size
  50.     private int codeLength = DEFAULT_CODE_LENGTH, line_number = DEFAULT_LINE_NUMBER, font_size = DEFAULT_FONT_SIZE;
  51.  
  52.     //variables
  53.     private String code;
  54.     private int padding_left, padding_top;
  55.     private Random random = new Random();
  56.     //验证码图片
  57.     public Bitmap createBitmap() {
  58.         padding_left = 0;
  59.  
  60.         Bitmap bp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
  61.         Canvas c = new Canvas(bp);
  62.  
  63.         code = createCode();
  64.  
  65.         c.drawColor(Color.WHITE);
  66.         Paint paint = new Paint();
  67.         paint.setAntiAlias(true);
  68.         paint.setTextSize(font_size);
  69.         //画验证码
  70.         for (int i = 0; i < code.length(); i++) {
  71.             randomTextStyle(paint);
  72.             randomPadding();
  73.             c.drawText(code.charAt(i) + "", padding_left, padding_top, paint);
  74.         }
  75.         //画线条
  76.         for (int i = 0; i < line_number; i++) {
  77.             drawLine(c, paint);
  78.         }
  79.  
  80.         //c.save(Canvas.ALL_SAVE_FLAG);//保存
  81.         c.save();
  82.         c.restore();
  83.         return bp;
  84.     }
  85.  
  86.     public String getCode() {
  87.         return code;
  88.     }
  89.  
  90.     //生成验证码
  91.     private String createCode() {
  92.         StringBuilder buffer = new StringBuilder();
  93.         for (int i = 0; i < codeLength; i++) {
  94.             buffer.append(CHARS[random.nextInt(CHARS.length)]);
  95.         }
  96.         return buffer.toString();
  97.     }
  98.     //画干扰线
  99.     private void drawLine(Canvas canvas, Paint paint) {
  100.         int color = randomColor();
  101.         int startX = random.nextInt(width);
  102.         int startY = random.nextInt(height);
  103.         int stopX = random.nextInt(width);
  104.         int stopY = random.nextInt(height);
  105.         paint.setStrokeWidth(1);
  106.         paint.setColor(color);
  107.         canvas.drawLine(startX, startY, stopX, stopY, paint);
  108.     }
  109.     //生成随机颜色
  110.     private int randomColor() {
  111.         return randomColor(1);
  112.     }
  113.  
  114.     private int randomColor(int rate) {
  115.         int red = random.nextInt(256) / rate;
  116.         int green = random.nextInt(256) / rate;
  117.         int blue = random.nextInt(256) / rate;
  118.         return Color.rgb(red, green, blue);
  119.     }
  120.     //随机生成文字样式，颜色，粗细，倾斜度
  121.     private void randomTextStyle(Paint paint) {
  122.         int color = randomColor();
  123.         paint.setColor(color);
  124.         paint.setFakeBoldText(random.nextBoolean());  //true为粗体，false为非粗体
  125.         float skewX = random.nextInt(11) / 10;
  126.         skewX = random.nextBoolean() ? skewX : -skewX;
  127.         paint.setTextSkewX(skewX); //float类型参数，负数表示右斜，整数左斜
  128.     }
  129.     //随机生成padding值
  130.     private void randomPadding() {
  131.         padding_left += base_padding_left + random.nextInt(range_padding_left);
  132.         padding_top = base_padding_top + random.nextInt(range_padding_top);
  133.     }
  134. }
