二、项目简介
该项目简介来自网络，具体内容需要自行测试
这款基于Android Studio开发的通讯录应用是一款功能完善、界面友好的联系人管理工具。应用采用现代化的设计理念，提供了完整的用户账号体系和数据管理功能。
1. 用户系统：支持账号注册、登录和密码修改，用户数据通过SharedPreferences安全存储。
2. 联系人管理：
- 支持添加、修改、删除联系人信息
- 联系人信息包括姓名、性别、多个电话号码、关系类型和备注等
- 提供详细的表单验证机制确保数据完整性
3. 搜索功能：
- 强大的联系人搜索功能
- 实时显示搜索结果数量
- 支持搜索结果的刷新和取消
4. 数据展示：
- 联系人列表视图
- 底部导航栏切换不同功能模块
- 个人中心显示统计信息
应用采用了Android开发的主流技术架构：
- 使用Fragment实现模块化界面
- 通过SQLite数据库持久化存储联系人数据
- 实现抽屉式导航界面
- 包含完善的表单验证和用户提示系统
- 采用响应式设计，适配不同屏幕尺寸

public class MainActivity extends AppCompatActivity {
private ActivityMainBinding mainBinding;
private Intent intent;
private boolean isRole = false; //登录的记录是否存在
/*--start--删除数据库--*/
// private static final String TAG = "MainActivity";
// private static final String DATABASE_NAME = "myLogInfo.db";
/*--end--*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainBinding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(mainBinding.getRoot());
Map<String, String> userInfo = SharedPreferencesService.getUserInfo(this);
//自动填充已有账号
if (!userInfo.isEmpty() && !Objects.requireNonNull(userInfo.get("account")).isEmpty()) {
isRole = true;
mainBinding.dlZhh.setText(userInfo.get("account"));
mainBinding.dlMm.setText(userInfo.get("password"));
}
//登录按钮
mainBinding.dlAnn.setOnClickListener(view -> {
String roleName = mainBinding.dlZhh.getText().toString().trim();
String password = mainBinding.dlMm.getText().toString().trim();
if (!roleName.isEmpty() && !password.isEmpty()) {
if (isRole) {
if (userInfo.get("account").equals(roleName) && userInfo.get("password").equals(password)) {
intent = new Intent(this, MainActivity2PageView.class);
startActivity(intent);
finish();
// startActivityIfNeeded(intent, 1);
} else {
Toast.makeText(MainActivity.this, "账号或密码错误", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(MainActivity.this, "账号不存在", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(MainActivity.this, "账号或密码不能为空", Toast.LENGTH_SHORT).show();
}
}
}
采用MVC模式，将数据存取逻辑封装在SP中。登录验证时先检查账号是否存在，再核对密码，最后跳转到主页面。注释中还包含了删除数据库的备用代码段，方便调试时使用。整体实现了基本的用户认证流程。
1. 使用ViewBinding替代findViewById来绑定界面元素
2. 通过SharedPreferences存储和获取用户登录信息
3. 实现了自动填充已保存账号密码的功能
4. 包含登录验证逻辑，检查账号密码是否正确
5. 提供注册账号和修改密码的跳转功能
6. 使用Toast提示用户操作反馈

将用户数据存储逻辑封装在SharedPreferencesService中，实现了基本的用户注册流程验证。注释中还保留了验证码生成和图片保存的参考实现，方便后续功能扩展。整体实现了注册页面的核心功能需求。
1. 用户注册功能：
- 检查两次输入密码是否一致
- 验证密码长度是否达到6位以上
- 通过SharedPreferences存储用户注册信息
- 注册成功跳转到主页面
2. 界面交互：
- 使用ViewBinding绑定视图组件
- 提供"已有账号"按钮返回登录页
- 使用Toast提示用户操作结果
3. 其他特性：
- 包含验证码生成功能(注释状态)
- 尝试实现返回栈管理(注释状态)

1. 核心功能：
- 联系人列表展示与滑动浏览
- 联系人搜索功能（支持模糊查询）
- 联系人详情查看与编辑
- 联系人删除功能（带确认弹窗）
- 列表快速返回顶部功能
2. 交互设计：
- 使用DrawerLayout实现右侧抽屉式搜索面板
- 列表项点击进入编辑界面
- 列表项长按触发删除操作
- 智能搜索提示（实时显示匹配结果数）
- 退出应用确认对话框
3. 技术实现：
- 采用ViewBinding进行视图绑定
- 使用SQLite数据库存储联系人数据
- 自定义ListAdapter适配器渲染列表
- 监听软键盘和滚动事件优化用户体验
- 使用TextWatcher实现搜索框实时反馈
4. 其他特性：
- 保持布局不被软键盘顶起
- 列表滚动时显示返回顶部按钮
- 搜索状态标记与管理
- 提供数据刷新功能
