SleepTracker Android 项目 - 完整开发文档

项目概述

这是一个使用 Jetpack Compose (Kotlin) 构建的睡眠追踪 Android 应用。项目从零开始在纯命令行 Linux 环境中搭建，包含完整的环境设置、代码实现和 APK 构建流程。

原始需求（用户原话）

你好我要搭建一个原生compose先进安卓代码项目从安装环境到直接你给我构建出APK，
项目名字叫 SleepTracker，
具体需求如下：
1. 在主页上有两个大的扇形按钮，一个是黑色的，另一个是白色的，
   黑色的按钮在左边，白色的按钮在右边。
2. 当用户点击其中一个按钮时，应该：
   a. 黑色按钮：开始睡眠计时。
   b. 白色按钮：停止睡眠计时（结束睡眠）。
   c. 播放音效（使用 ogg 文件格式）。
3. 当用户点击按钮时，整个屏幕应该被选中的颜色"淹没"：
   a. 点击黑色按钮，屏幕应逐渐被黑色淹没（动画效果）。
   b. 点击白色按钮，屏幕应逐渐被白色淹没（动画效果）。
4. 记录系统：
   a. 当点击黑色按钮时，记录开始时间。
   b. 当点击白色按钮时，记录结束时间。
   c. 所有记录应保存在本地数据库中。
5. 历史记录页面：
   a. 显示所有睡眠记录。
   b. 支持撤销最后一次记录。
   c. 支持编辑记录（修改开始/结束时间）。
   d. 支持删除记录。
   e. 使用类似思维导图的时间轴方式展示（不是实际的思维导图）。
6. UI 设计：
   a. Telegram 风格的界面设计。
   b. 使用数学动画（弹簧动画）实现流畅效果。
7. 代码结构：
   a. 所有代码需要模块化，每个功能放在不同的文件中。
   b. 方便 AI 持续开发和维护。

核心代码实现

1. 数据模型 (SleepRecord.kt)

package com.sleeplabs.sleeplabs.data

import kotlinx.serialization.Serializable

@Serializable
data class SleepRecord(
    val id: String = java.util.UUID.randomUUID().toString(),
    val startTime: Long,
    val endTime: Long,
    val createdAt: Long = System.currentTimeMillis()
) {
    val duration: Long
        get() = endTime - startTime
}

2. 数据持久化 (SleepDatabase.kt)

使用 DataStore 存储睡眠记录：

package com.sleeplabs.sleeplabs.data

import android.content.Context
import androidx.datastore.core.DataStore
import androidx.datastore.preferences.core.Preferences
import androidx.datastore.preferences.core.edit
import androidx.datastore.preferences.core.stringPreferencesKey
import androidx.datastore.preferences.preferencesDataStore
import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.first
import kotlinx.coroutines.flow.map
import kotlinx.serialization.encodeToString
import kotlinx.serialization.json.Json

val Context.dataStore: DataStore<Preferences> by preferencesDataStore(name = "sleep_records")

class SleepDatabase(private val context: Context) {
    private val RECORDS_KEY = stringPreferencesKey("sleep_records")
    private val json = Json { ignoreUnknownKeys = true }

    val records: Flow<List<SleepRecord>> = context.dataStore.data
        .map { preferences ->
            val recordsJson = preferences[RECORDS_KEY] ?: "[]"
            try {
                json.decodeFromString<List<SleepRecord>>(recordsJson)
            } catch (e: Exception) {
                emptyList()
            }
        }

    suspend fun addRecord(record: SleepRecord) {
        val currentRecords = records.first().toMutableList()
        currentRecords.add(0, record)
        saveRecords(currentRecords)
    }

    suspend fun updateRecord(record: SleepRecord) {
        val currentRecords = records.first().toMutableList()
        val index = currentRecords.indexOfFirst { it.id == record.id }
        if (index != -1) {
            currentRecords[index] = record
            saveRecords(currentRecords)
        }
    }

    suspend fun deleteRecord(id: String) {
        val currentRecords = records.first().toMutableList()
        currentRecords.removeAll { it.id == id }
        saveRecords(currentRecords)
    }

    suspend fun undoLast(): SleepRecord? {
        val currentRecords = records.first()
        if (currentRecords.isEmpty()) return null
        val lastRecord = currentRecords.first()
        deleteRecord(lastRecord.id)
        return lastRecord
    }

    private suspend fun saveRecords(records: List<SleepRecord>) {
        context.dataStore.edit { preferences ->
            preferences[RECORDS_KEY] = json.encodeToString(records)
        }
    }
}

3. ViewModel (SleepViewModel.kt)

package com.sleeplabs.sleeplabs.viewmodel

import androidx.lifecycle.ViewModel
import androidx.lifecycle.viewModelScope
import com.sleeplabs.sleeplabs.data.SleepDatabase
import com.sleeplabs.sleeplabs.data.SleepRecord
import kotlinx.coroutines.flow.*
import kotlinx.coroutines.launch

class SleepViewModel(private val database: SleepDatabase) : ViewModel() {
    private val _isSleeping = MutableStateFlow(false)
    val isSleeping: StateFlow<Boolean> = _isSleeping.asStateFlow()

    private val _startTime = MutableStateFlow(0L)
    val startTime: StateFlow<Long> = _startTime.asStateFlow()

    private val _selectedColor = MutableStateFlow<String?>(null)
    val selectedColor: StateFlow<String?> = _selectedColor.asStateFlow()

    val records: StateFlow<List<SleepRecord>> = database.records
        .stateIn(viewModelScope, SharingStarted.Lazily, emptyList())

    fun toggleSleep() {
        viewModelScope.launch {
            if (_isSleeping.value) {
                // 停止睡眠
                val record = SleepRecord(
                    startTime = _startTime.value,
                    endTime = System.currentTimeMillis()
                )
                database.addRecord(record)
                _isSleeping.value = false
                _startTime.value = 0L
                _selectedColor.value = "white"
            } else {
                // 开始睡眠
                _isSleeping.value = true
                _startTime.value = System.currentTimeMillis()
                _selectedColor.value = "black"
            }
        }
    }

    fun resetColor() {
        _selectedColor.value = null
    }

    fun undoLast() {
        viewModelScope.launch {
            database.undoLast()
        }
    }

    fun deleteRecord(id: String) {
        viewModelScope.launch {
            database.deleteRecord(id)
        }
    }

    fun updateRecord(record: SleepRecord) {
        viewModelScope.launch {
            database.updateRecord(record)
        }
    }
}

            val radius = kotlin.math.max(width, height) * 0.7f

            val path = Path()

音频文件准备

创建空音频文件（占位）

cd /workspace/SleepTracker/app/src/main/res/raw

# 创建空的 OGG 文件（实际使用时应替换为真实音效）
touch black_sleep.ogg
touch white_wake.ogg

生成真实音频文件（可选）

如果有 ffmpeg 可以生成音效：

# 安装 ffmpeg
apt-get install -y ffmpeg

# 生成简单的音效
ffmpeg -f lavfi -i "sine=frequency=440:duration=0.5" -c:a libvorbis -b:a 64k black_sleep.ogg
ffmpeg -f lavfi -i "sine=frequency=880:duration=0.5" -c:a libvorbis -b:a 64k white_wake.ogg

构建和运行命令

设置环境变量（每次运行前执行）

export ANDROID_HOME=/usr/lib/android-sdk
export ANDROID_SDK_ROOT=/usr/lib/android-sdk
export PATH="$PATH:$ANDROID_HOME/cmdline-tools/latest/bin:$ANDROID_HOME/platform-tools"
export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
export PATH="$PATH:/opt/gradle/bin"

构建 APK

cd /workspace/SleepTracker

# 清理并构建
gradle --no-daemon clean
gradle --no-daemon assembleDebug

# 或者直接构建（增量）
gradle --no-daemon assembleDebug

APK 输出位置

/workspace/SleepTracker/app/build/outputs/apk/debug/app-debug.apk

安装到设备（如已连接）

adb install -r /workspace/SleepTracker/app/build/outputs/apk/debug/app-debug.apk

解包和查看 APK 内容

cd /workspace/SleepTracker

# 解压 APK 查看
mkdir -p apk_unpacked
unzip -o app/build/outputs/apk/debug/app-debug.apk -d apk_unpacked/

# 查看 APK 内容结构
tree apk_unpacked/ -L 3

# 查看 AndroidManifest
cat apk_unpacked/AndroidManifest.xml

# 查看资源
ls -la apk_unpacked/res/

清理构建

cd /workspace/SleepTracker
gradle --no-daemon clean

查看已安装的 SDK 组件

sdkmanager --list_installed

更新 SDK 组件

sdkmanager --update

遇到的问题和解决方案

问题 1: SDK 下载超时

症状: wget 下载命令行工具超时

解决方案:

# 使用备用链接或重试
wget https://dl.google.com/android/repository/commandlinetools-linux-9477386_latest.zip -O cmdline-tools.zip

问题 2: compileSdk 版本不兼容

症状: Error: SDK version 34 is not available

解决方案:

  • 在 app/build.gradle.kts 中将 compileSdk 从 34 改为 35
  • 安装 platform 35: sdkmanager "platforms;android-35"

问题 3: Import 语句错误

症状: 未解析的引用 import kotlinx.coroutines.flow.first

解决方案: 确保在文件顶部添加正确的 import

问题 4: 类型推断错误

症状: Type inference failed

解决方案: 添加显式类型声明，例如：

val records: List<SleepRecord> = database.records.first()

问题 5: 图标未找到

症状: Icons.Default.Undo 未解析

解决方案: 使用 Icons.Outlined.RestartAlt 替代，或添加依赖：

implementation("androidx.compose.material:material-icons-extended")

问题 6: README.txt 导致构建错误

症状: raw 文件夹中的非资源文件导致构建失败

解决方案: 删除 raw 文件夹中的 README.txt 文件

问题 7: DrawScope.drawPath 导入错误

症状: 未解析的引用 drawIntoCanvas

解决方案: 移除不必要的 import，DrawScope 已经包含 drawPath 方法

项目特点

  1. 模块化设计: 每个功能模块独立文件，便于 AI 持续开发
