+# 目标管理功能实现文档
+
+## 功能概述
+
+根据用户需求，实现了一个高保真的目标管理页面，包含以下主要功能：
+
+1. **横向滑动的待办事项卡片** - 首屏展示1.5张卡片
+2. **时间筛选选择器** - 支持按天/周/月筛选
+3. **可滚动的时间轴** - 展示选中日期的具体任务，支持上下左右滑动
+
+## 组件架构
+
+### 核心组件
+
+#### 1. TodoCard.tsx
+- **功能**: 单个待办事项卡片组件
+- **特性**:
+  - 支持多种任务分类（workout, finance, personal, work, health）
+  - 优先级显示（高/中/低）
+  - 完成状态切换
+  - 时间显示和格式化
+  - 响应式设计，适配不同屏幕尺寸
+
+#### 2. TodoCarousel.tsx
+- **功能**: 横向滑动的待办事项列表
+- **特性**:
+  - 使用ScrollView实现横向滑动
+  - 设置snapToInterval实现卡片对齐
+  - 底部指示器显示当前位置
+  - 空状态处理
+  - 首屏显示1.5张卡片的设计
+
+#### 3. TimeTabSelector.tsx
+- **功能**: 时间筛选选择器
+- **特性**:
+  - 支持天/周/月三种筛选模式
+  - 平滑的选择动画
+  - 符合设计系统的UI风格
+
+#### 4. TimelineSchedule.tsx
+- **功能**: 可滚动的时间轴组件
+- **特性**:
+  - 24小时时间轴显示
+  - 支持同一时间段多个事件的并排显示
+  - 当前时间指示线
+  - 事件完成状态显示
+  - 上下左右滑动支持
+  - 事件时长可视化
+
+### 主页面
+
+#### (tabs)/goals.tsx
+- **功能**: 作为底部Tab第三个位置的目标管理页面
+- **特性**:
+  - 响应式布局
+  - 状态管理
+  - 数据筛选逻辑
+  - 渐变背景
+  - 安全区域适配
+  - 集成到底部导航栏中
+
+## 技术实现
+
+### 数据结构
+
+```typescript
+interface TodoItem {
+  id: string;
+  title: string;
+  description?: string;
+  time: string;
+  category: 'workout' | 'finance' | 'personal' | 'work' | 'health';
+  isCompleted?: boolean;
+  priority?: 'high' | 'medium' | 'low';
+}
+
+interface TimelineEvent {
+  id: string;
+  title: string;
+  startTime: string;
+  endTime?: string;
+  category: TodoItem['category'];
+  isCompleted?: boolean;
+}
+```
+
+### 核心功能
+
+1. **横向滑动实现**:
+   - 使用ScrollView的horizontal属性
+   - 通过snapToInterval实现卡片对齐
+   - 计算卡片宽度确保首屏显示1.5张
+
+2. **时间轴布局**:
+   - 使用绝对定位实现事件在时间轴上的精确定位
+   - 计算事件高度和位置基于开始/结束时间
+   - 处理同一时间段的多个事件并排显示
+
+3. **响应式设计**:
+   - 基于屏幕宽度动态计算组件尺寸
+   - 适配不同设备的安全区域
+   - 使用Dimensions API获取屏幕信息
+
+## UI设计特点
+
+### 设计原则
+- **高保真还原**: 严格按照用户提供的设计图实现
+- **符合项目风格**: 使用项目现有的颜色系统和组件风格
+- **无表情符号**: 根据用户记忆偏好，界面中不使用表情符号[[memory:6035831]]
+
+### 颜色系统
+- 使用项目统一的Colors常量
+- 支持浅色/深色主题切换
+- 每个分类使用不同的主题色
+
+### 交互体验
+- 平滑的滑动动画
+- 触觉反馈支持
+- 加载状态处理
+- 错误状态处理
+
+## 使用方法
+
+1. **访问页面**:
+   - 直接点击底部导航栏第三个位置的"目标"tab
+   - 或通过个人页面的"目标管理"菜单项
+   - 或访问"目标管理演示"查看功能介绍
+
+2. **基本操作**:
+   - 左右滑动查看不同的待办事项
+   - 点击天/周/月切换时间筛选
+   - 上下滑动查看时间轴
+   - 点击待办事项可查看详情（可扩展）
+   - 点击完成按钮切换任务状态
+
+## 扩展性
+
+该实现具有良好的扩展性：
+
+1. **数据源**: 可以轻松接入真实的API数据
+2. **功能扩展**: 可以添加新增/编辑/删除任务功能
+3. **样式定制**: 基于设计系统，可以轻松调整样式
+4. **组件复用**: 各个组件都可以在其他页面中复用
+
