Android开发使用框架手把手搭建一个简单项目
前言：
年关将近，公司也没有什么业务了，基本上都是些旧项目维护以及客户给出的功能改动等小需求。正好其中有个需求是关于某个维护了近五年的小项目功能改动，由于这个项目当时搭建得并不好再加上后续的功能变化和最初设计时出入比较大，以至于每次收到有关这个项目的新需求时我都会非常头疼，于是就趁着这段业务空闲期把整个项目优化重构一遍，这样一来就算后续有了新的改动需求维护这个项目的同事也不再会因为 “在屎山里面加屎” 而感到头疼了。整个重构过程包括后续的测试优化前前后后大概花了两个星期的时间，在这里把整个重构的流程和思路都记录一下，方便自己对项目搭建能力的巩固和归纳总结，也适用于一些刚入门不久想要提升项目搭建能力的同学参考和交流学习。由于自身的才疏学浅在项目搭建过程中可能会有许多的错漏和不足之处还请大家见谅，也希望各位大佬能够及时纠正并指点一二！
一、项目描述
1. 需求描述
一款适用于基于 android 系统的定制手表通过各种连接方式以不同的通信链路连接北斗设备进行指令交互以实现 “监测并反馈实时的设备状况” 和 “通过卫星消息收发文本、语音以及拆包图片” 以及除这两个主要功能以外的其他次要功能。其中通信链路包括：BLE低功耗蓝牙、经典蓝牙、USB Host、USB Accessory 和 Serial Port串口
2. 难点分析
项目的整体功能非常简单：实现基本的连接功能之后对设备输出反馈的标准北斗协议、设备自定义协议、以及公司自定的消息内容协议进行解析，获取到对应的设备参数和通信内容并实时更新页面及功能即可。
其中相对复杂的部分大概有以下几点：
1. 由于兼容的通信链路比较多并且某些链路的运作方式与其他链路的同质性差异较大导致项目中的连接管理功能部分变得非常臃肿复杂
2. 由于兼容的设备类型比较多，除了兼容标准的北斗协议以外还要兼容各种设备自身的特有指令和卫星消息中的自定义的内容协议，不同的协议反馈了不同功能和模块需要用到的参数并且其中有许多参数是多个模块同时需要用到亦或是一个模块用到了多种不同协议参数的场景导致项目中对获取到的数据参数分类和管理困难
3. 由于卫星通信方式较为特殊，对设备实时反馈的设备状态及环境因素比较严格，并且需要根据不同类型的北斗设备和北斗卡来限制各自发送卫星消息的发送条件、发送内容长度和发送间隔，特别是图片分包发送功能中的发送流程控制逻辑非常复杂
3. 项目说明
项目采用的是 Java 和 Kotlin 两种语言混合开发，采用 MVVM 框架，为了规范和项目后续的维护改动采用多模块开发方式。整个项目中使用到的各开发技术点大致有：ViewModel/ViewBinding等Jetpack组件、Kotlin协程、EventBus观察者模式、路由、GreenDao数据库、多模块开发等等
二、项目搭建
1. 基本结构
项目主要拆分为3个模块（壳工程以外），分别是：主页面模块、数据处理和工具模块、数据存储模块（感觉这里有点为拆而拆了.. 没办法这个APP的功能实在太少）其实在这里数据连接和协议解析部分也应该单独抽出来作为各自单独的一个模块，正好最近有个任务是为了方便客户进行二次开发让我设计编写通信链路的SDK和设备协议解析的SDK，等开发完成之后再整合到这个项目里面
在这里我先从项目的主要和基本部分开始再到页面和功能一步步地分解和说明
1. 主程序
主程序中只执行一系列项目前置初始化工作，需要进行初始化的任务有：全局帮助类（提供APP上下文环境）初始化、MMKV工具初始化、系统信息工具初始化、GreenDao数据库初始化、Arouter路由初始化、中山大学低码率语音和渐进式图片压缩库初始化、全局异常捕获初始化、注册页面生命周期变化监听、注册系统定边变化监听
在这里使用了前段时间学习的某个大型项目框架中用到的拓扑算法来对各初始化任务执行先后进行排序
class MainApplication:Application(), ViewModelStoreOwner {
// 常量 ------------------------------------------
val TAG = "MainApplication"
var aliveActivityCount = 0 // 已开启页面统计
companion object {
val instance: MainApplication by lazy { Holder.INSTANCE }
}
private object Holder {
lateinit var INSTANCE: MainApplication
}
// companion object{
// private lateinit var mainApplication: MainApplication
// fun getInstance(): MainApplication {
// return mainApplication
// }
// }
override fun onCreate() {
super.onCreate()
Holder.INSTANCE = this
// mainApplication = this;
// 执行程序初始化
TaskDispatcher.init(this) // 初始化调度器
TaskDispatcher.createInstance().addTask(InitAppUtilTask(this))
.addTask(InitMmkvTask())
.addTask(InitSystemInfoTask())
.addTask(InitGreenDaoTask())
.addTask(InitArouterTask())
.addTask(InitZDCompression())
.addTask(InitCatchException())
.start()
TaskDispatcher.createInstance().await()
// Activity 生命周期注册
registerActivityLifecycleCallbacks(object : ActivityLifecycleCallbacks{
override fun onActivityCreated(p0: Activity, p1: Bundle?) {
Log.d(TAG, "onActivityCreated: 打开页面 $p0.localClassName")
ActivityManagementUtils.getInstance().push(p0)
}
override fun onActivityStarted(p0: Activity) {
aliveActivityCount++;if (aliveActivityCount == 1) { Log.e(TAG, "切换到前台") }
}
override fun onActivityResumed(p0: Activity) {}
override fun onActivityPaused(p0: Activity) {}
override fun onActivityStopped(p0: Activity) {
aliveActivityCount--;if (aliveActivityCount == 0) { Log.e(TAG, "切换到后台") }
}
override fun onActivitySaveInstanceState(p0: Activity, p1: Bundle) {}
override fun onActivityDestroyed(p0: Activity) {
Log.d(TAG, "onActivityCreated: 关闭页面 $p0.localClassName")
ActivityManagementUtils.getInstance().pop(p0)
}
})
// 注册系统定位变化监听
SystemLocationUtils.init(this)
}
private val appViewModelStore: ViewModelStore by lazy { ViewModelStore() }
override fun getViewModelStore(): ViewModelStore {
return appViewModelStore
}
}2. 基类
2.1 Activity 基类
页面基类分为三种：普通基类、ViewBinding基类、MVVM基类
依据不同情况选择实现，其中ViewBinding基类继承于普通基类，MVVM基类继承于ViewBinding基类，因此当需要进行全局性的页面修改时只要对普通基类进行修改即可
2.1.1 普通基类
APP功能较少，在基类中没有进行过多的额外方法定义，在这里对其中几个主要的方法进行说明：beforeSetLayout()：在设置页面布局之前执行，预留，在这个项目中并没有用上，抽象方法必须实现
setLayout()：指定页面布局对象，抽象方法必须实现
setActivityLayout()：主要的设置布局执行方法，从setLayout()中获取布局对象并判断获取的类型为布局id还是view进行相应的绑定操作。开放方法，在 ViewBinding 基类中重写这个方法为通过反射直接获取指定的 ViewBinding 对象
initView(savedInstanceState: Bundle?)：初始化页面方法，在主线程中执行，主要执行对UI相关事件的初始化操作，抽象方法必须实现
initData()：初始化数据(主线程)，抽象方法必须实现
initDataSuspend()：初始化数据(子线程)，抽象方法必须实现
abstract class BaseActivity : AppCompatActivity(){
val TAG : String? = this::class.java.simpleName
val APP : Application by lazy { ApplicationUtils.getApplication() }
lateinit var activity_window : Window
lateinit var my_context : Context
var title_textview: TextView? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
activity_window = window
my_context = this
beforeSetLayout()
supportActionBar?.let {it.hide()} // 隐藏标题栏
setActivityLayout() // 绑定布局
try { title_textview = findViewById(R.id.title) } catch (e: Exception) { loge("这个页面没有 title bar") } // 必须放在初始化布局之后，初始化数据之前
setOrientationPortrait() // 锁定垂直布局
initView(savedInstanceState); // 初始化页面
CoroutineScope(Dispatchers.Main).launch{
initData(); // 初始化数据
withContext(Dispatchers.IO){
initDataSuspend()
}
}
if(enableEventBus()){EventBus.getDefault().register(this)} // 是否需要开启 EventBus 功能
}
abstract fun setLayout(): Any?
abstract fun beforeSetLayout()
abstract fun initView(savedInstanceState: Bundle?)
abstract fun initData()
abstract suspend fun initDataSuspend()
open fun enableEventBus():Boolean=false
// 绑定布局
open fun setActivityLayout(){
loge("手动绑定布局")
setLayout()?.let {
if (setLayout() is Int) {
setContentView((setLayout() as Int?)!!) // 手动绑定 R.layout.id
} else {
setContentView(setLayout() as View?) // 手动绑定 ViewBinding
}
}
}
// 打印 loge
fun loge(log: String?) {
Log.e(TAG, log!!)
}
// 设置页面标题
fun setTitle(title : String){
loge("设置页面标题：$title")
title_textview?.let { it.text = title }
}
// 锁定页面垂直
fun setOrientationPortrait() {
requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
}
override fun onDestroy() {
if(enableEventBus()){EventBus.getDefault().unregister(this)}
// unregisterSlideBack()
super.onDestroy()
}
// 页面返回响应
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
loge("页面返回，请求码是：$requestCode 响应码是：$resultCode")
}
// 权限申请响应
override fun onRequestPermissionsResult(requestCode: Int, permissions: Array, grantResults: IntArray) {
loge("请求权限码是：" + requestCode + " / 权限列表：" + Arrays.toString(permissions) + " / 结果列表：" + Arrays.toString(grantResults))
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
}
} 2.1.2 ViewBinding 基类
继承于普通基类，重写setActivityLayout()设置布局方法为：通过反射获取指定的 ViewBinding 对象并绑定页面布局，声明时需传入指定的 ViewBinding 对象类型VB
abstract class BaseViewBindingActivity : BaseActivity() {
lateinit var viewBinding : VB
// 重写设置布局方法
override fun setActivityLayout() {
// 通过反射获取到对应的 Binding 对象并拿到他的 Binding.inflate(layoutInflater) 方法执行
val type = javaClass.genericSuperclass // getClass().getGenericSuperclass();
// 拿到 ViewBinding 类对象
val vbClass: Class = type!!.saveAs().actualTypeArguments[0].saveAs() // genericSuperclass 强转为 ParameterizedType
// 拿到 ViewBinding 类的inflate方法
val method = vbClass.getDeclaredMethod("inflate", LayoutInflater::class.java)
// 执行 ViewBinding.inflate(getLayoutInflater()); 前面的变量已声明类型VB所以不需要再指定
viewBinding = method.invoke(this, layoutInflater)!!.saveAsUnChecked()
setContentView(viewBinding.root) // 设置布局
}
override fun setLayout(): Any? {return null} // 直接返回 null 就好了
} 2.1.3 MVVM 基类
继承于 ViewBinding 基类，重写initData()方法，通过反射获取指定的 ViewModel 对象，声明时需传入指定的 ViewModel 对象类型VB和 Boolean 类型参数决定使用的 ViewModel 生命周期，子类实现时需要执行super.initData()方法
abstract class BaseMVVMActivity(global_model:Boolean = false) : BaseViewBindingActivity(){
val global = global_model // 是否全局使用的 ViewModel
lateinit var viewModel: VM
// 第一次重写，子类还要重写一次并且必须调用super方法执行下面的初始化
override fun initData() {
// 反射创建 ViewModel 对象
// val argument = (this.javaClass.genericSuperclass as ParameterizedType).actualTypeArguments
if(global){loge("使用全局ViewModel")}else{loge("使用临时ViewModel")}
viewModel = if(global){
// 使用全局 ViewModel
// ApplicationUtils.getGlobalViewModel(argument[1] as Class)!!
val superClass = this::class.supertypes
loge("构造函数：${superClass[0]}")
val kArgument = superClass[0].arguments
loge("ViewModel对象：${kArgument[1]}")
val classVM = kArgument[1].type?.classifier
val globalViewModelStore : ViewModelStore =
if(ApplicationUtils.globalViewModelStore==null){
ApplicationUtils.globalViewModelStore = viewModelStore
viewModelStore
}else{
loge("已有 globalViewModelStore ")
ApplicationUtils.globalViewModelStore!!
}
ViewModelLazy(
classVM as KClass,
{ globalViewModelStore },
{ defaultViewModelProviderFactory }
).value
}else{
val argument = (this.javaClass.genericSuperclass as ParameterizedType).actualTypeArguments
ViewModelProvider(this).get(argument[1] as Class)
}
}
} 2.2 Fragment 基类
思路与Activity基类相似，不做赘述
2.2.1 普通基类
abstract class BaseFragment:Fragment() {
private var TAG:String = javaClass.name
val APP : Application by lazy { ApplicationUtils.getApplication() }
lateinit var my_context: Context;
lateinit var title: TextView;
lateinit var back: ImageView;
lateinit var layoutView:View;
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Log.d(TAG, "onCreate: 打开 Fragment")
setHasOptionsMenu(true) // 开启菜单项
beforeSetLayout()
my_context = requireContext()
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
layoutView = if(setLayout() is Int) inflater.inflate((setLayout() as Int),container,false) else (setLayout() as View) // 使用 R.layout 或 ViewBinding
return layoutView
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
getView()?.let { initView(it) } // 初始化控件事件
CoroutineScope(Dispatchers.Main).launch{
initData(); // 初始化数据
withContext(Dispatchers.IO){
initDataSuspend()
}
}
}
abstract fun beforeSetLayout()
abstract fun setLayout():Any?
abstract fun initView(view: View)
abstract fun initData()
abstract suspend fun initDataSuspend()
fun loge(log:String){
Log.e(TAG, log )
}
override fun onDestroy() {
Log.d(TAG, "onCreate: 关闭 Fragment")
super.onDestroy()
}
}2.2.2 ViewBinding 基类
abstract class BaseViewBindingFragment : BaseFragment() {
lateinit var viewBinding : VB
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
val type = javaClass.genericSuperclass
val vbClass: Class = type!!.saveAs().actualTypeArguments[0].saveAs()
val method = vbClass.getDeclaredMethod("inflate", LayoutInflater::class.java)
viewBinding = method.invoke(this, layoutInflater)!!.saveAsUnChecked()
return viewBinding.root
}
override fun setLayout(): Any? { return null }
} 2.2.3 MVVM 基类
abstract class BaseMVVMFragment(global_model:Boolean = false) : BaseViewBindingFragment() {
val global = global_model // 是否全局使用的 ViewModel
lateinit var viewModel: VM
override fun initData() {
// 反射创建 ViewModel 对象
if(global){loge("使用全局ViewModel")}else{loge("使用临时ViewModel")}
viewModel = if(global){
// 使用全局 ViewModel
val superClass = this::class.supertypes
loge("构造函数：${superClass[0]}")
val kArgument = superClass[0].arguments
loge("ViewModel对象：${kArgument[1]}")
val classVM = kArgument[1].type?.classifier
val globalViewModelStore : ViewModelStore =
if(ApplicationUtils.globalViewModelStore==null){
ApplicationUtils.globalViewModelStore = viewModelStore
viewModelStore
}else{
loge("已有 globalViewModelStore ")
ApplicationUtils.globalViewModelStore!!
}
ViewModelLazy(
classVM as KClass,
{ globalViewModelStore },
{ defaultViewModelProviderFactory }
).value
}else{
val argument = (this.javaClass.genericSuperclass as ParameterizedType).actualTypeArguments
ViewModelProvider(this).get(argument[1] as Class)
}
}
} 2.3 Adapter 基类
子类实现简单，声明时需指定子数据类型及子布局的 ViewBinding 对象，兼容头脚布局功能
2.3.1 Adapter 基类
abstract class BaseRecyclerViewAdapter : RecyclerView.Adapter() {
// 数据
private var data: MutableList = mutableListOf()
// 这个项目用不上
private lateinit var mHeaderLayout: LinearLayout // 头布局
private lateinit var mFooterLayout: LinearLayout // 脚布局
companion object {
const val HEADER_VIEW = 0x10000111
const val FOOTER_VIEW = 0x10000222
}
// 接口 ------------------------------------------------------------------------------------
var onItemClickListener: ((view: View, position: Int) -> Unit)? = null // 点击
var onItemLongClickListener: ((view: View, position: Int) -> Boolean) = { view, position -> false } // 长按
/**
* 子类不可重载，如果有需要请重写[onCreateDefViewHolder]实现自定义ViewHolder
* 或者重写[getViewBinding]传入布局，不需要创建ViewHolder
*/
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BaseViewHolder {
val baseViewHolder: BaseViewHolder
when (viewType) {
// 头、脚、子布局
HEADER_VIEW -> {

if (headerParent is ViewGroup) {
headerParent.removeView(mHeaderLayout)
}
baseViewHolder = BaseViewHolder(mHeaderLayout)
}
FOOTER_VIEW -> {
val headerParent: ViewParent? = mFooterLayout.parent
if (headerParent is ViewGroup) {
headerParent.removeView(mFooterLayout)
}
baseViewHolder = BaseViewHolder(mFooterLayout)
}
else -> {
val layoutInflater = LayoutInflater.from(parent.context)
baseViewHolder = onCreateDefViewHolder(layoutInflater, parent, viewType)
bindViewClickListener(baseViewHolder) // 设置点击事件
}
}
return baseViewHolder
}
/**

*/
override fun onBindViewHolder(holder: BaseViewHolder, position: Int) {
when (holder.itemViewType) {
HEADER_VIEW, FOOTER_VIEW -> {
return
}
else -> {
//holder必须继承自BaseBindViewHolder
if (holder is BaseBindViewHolder<*>) {
holder as BaseBindViewHolder
val realPosition = position - headerLayoutCount
val item = getItem(realPosition)
item?.let {
onBindDefViewHolder(holder, it, realPosition)
}
}
}
}

// 重写此方法，返回 ViewType

}
} 2.3.2 ViewHolder 基类
open class BaseViewHolder(rootView: View) : RecyclerView.ViewHolder(rootView)
open class BaseBindViewHolder(val binding: B) : BaseViewHolder(binding.root)2.3.3 实现例子
用一个蓝牙列表作为简单的例子吧
public class BluetoothListAdapter extends BaseRecyclerViewAdapter {
@NonNull
@Override
public AdapterBluetoothItemBinding getViewBinding(@NonNull LayoutInflater layoutInflater, @NonNull ViewGroup parent, int viewType) {
return AdapterBluetoothItemBinding.inflate(layoutInflater,parent,false);
}
@Override
protected void onBindDefViewHolder(@NonNull BaseBindViewHolder holder, @Nullable BluetoothDevice item, int position) {
if(item==null){return;}
AdapterBluetoothItemBinding binding = holder.getBinding();
if(binding!=null){
binding.deviceName.setText(item.getName());
binding.deviceAddr.setText(item.getAddress());
}
}
} 2.4 ViewModel 基类
ViewModel 基类里面主要定义了三个基本方法
2.4.1 倒计时任务
由于北斗通信存在频度限制因此程序在每次执行通信操作之后需要进行倒计时，这里通过 flow 定义一个简单的倒计时方法
fun countDownCoroutines(
total: Int,
scope: CoroutineScope,
onTick: (Int) -> Unit,
onStart: (() -> Unit)? = null,
onFinish: (() -> Unit)? = null,
): Job {
return flow {
for (i in total downTo 0) {
emit(i)
delay(1000)
}
}
.flowOn(Dispatchers.Main)
.onStart { onStart?.invoke() }
.onCompletion { onFinish?.invoke() } // 等效 java finally
.onEach { onTick.invoke(it) } // 每次倒计时时执行
.launchIn(scope)
}2.4.2 获取数据方法
在子线程中获取数据
suspend fun safeApiCallWithResult(
responseBlock: suspend () -> T?
): T? {
try {
// 子线程执行请求函数获取数据 10秒超时
val response = withContext(Dispatchers.IO) {
withTimeout(10 * 1000) {
responseBlock()
}
} ?: return null // 为空返回 null
return response // 返回数据
} catch (e: Exception) {
e.printStackTrace()
}
return null
} 2.4.3 获取数据并在主线程中处理数据
与第二个方法联合使用，现在子线程中获取数据再切回到主线程中进行UI刷新等任务，这种方法也适用于网络请求数据的情景但这个项目中并没有涉及到网络编程的部分因此获取数据操作大多都只是在数据库中获取数据
fun launchUIWithResult(
responseBlock: suspend () -> T?, // 挂起函数拿到数据：无输入 → 输出T
successBlock: (T?) -> Unit // 处理函数
) {
// 在主线程调用
viewModelScope.launch(Dispatchers.Main) {
val result = safeApiCallWithResult(responseBlock) // 子线程获取数据
result?.let { successBlock(it) } // 主线程处理结果
}
} 2.5 Connector 基类
本项目的精华所在，通过分析各种通信链路总结归纳出来的通信链路连接器基类。
以下是各通信链路的连接流程：
低功耗蓝牙：判断权限 一> 开启扫描 一> 获取设备列表 一> 判断权限 一> 连接
经典蓝牙：判断权限 一> 开启扫描 一> 获取设备列表 一> 判断权限(配对) 一> 连接
USB Host： 获取设备列表 一> 判断权限 一> 连接
USB Accessory： 获取设备列表 一> 判断权限 一> 连接
Serial Port：判断权限 一> 获取可用地址列表 一> 判断权限 一> 打开
通过从以上流程大致可以归纳出以下几个共用方法：
2.5.1 获取可用设备列表
除蓝牙需要注册广播监听系统扫描结果逐个拿到子设备对象不符合以外其他连接方式都可以一次性获取到所有的子连接对象，但Serial Port在获取之前还需要作判断权限的前置操作因此再定义一个判断条件的前置方法
open suspend fun getDevicesWithCondition(
before: (()->Unit)?=null,
condition: (()->Boolean),
search: suspend ()->MutableList?,
after: (()->Unit)?=null
): MutableList? {
try {
before?.let { it.invoke() }
if(condition()){
val devices = withContext(Dispatchers.IO){
withTimeout(10*1000){
search()
}
}
return if(devices!=null){
after?.invoke()
devices
}else{
null
}
}else{
Log.e(TAG, "获取设备条件不足！")
return null
}
}catch (e:Exception){
e.printStackTrace()
return null
}
} 方法分析：若定义了前置准备工作则执行，再根据条件判断是否执行获取设备列表方法，若满足条件并获取设备成功则执行后置操作并返回设备对象，否则返回null
2.5.2 连接设备
所有的连接方式都是在连接设备之前先进行权限判断，因此像获取可用设备方法一样定义一个条件判断方法再决定是否执行连接操作即可
open fun connectDeviceWithCondition(
device: T,
before: (()->Unit)?=null, // 前置准备
condition: (()->Boolean), // 前置条件
connectWithTransfer:(T)->Boolean, // 连接操作
conditionFail: (()->Unit)?=null, // 条件检测失败
success: (()->Unit)?=null, // 成功
fail: (()->Unit)?=null, // 失败
){
before?.let { it.invoke() }
if(condition()){
if(connectWithTransfer(device)){
Log.e(TAG, "设备连接成功" )
success?.let { it.invoke() }
}else{
Log.e(TAG, "设备连接失败" )
fail?.let { it.invoke() }
}
}else{
Log.e(TAG, "连接条件不足！")
conditionFail?.let { it.invoke() }
}
} 方法分析：若定义了前置准备工作则执行，再根据条件判断是否执行连接设备操作，若满足条件并连接设备成功则执行连接成功后置操作，若连接设备失败则执行连接失败后置处理，若不满足连接条件则执行条件失败后置处理
2.5.3 根据条件自动连接设备
由于连接的设备都是公司自己研发的设备，往往会在项目说明文件中直接指出所需连接设备的设备标识，因此通常我们并不需要将获取可用设备列表和连接设备分开操作，而是在搜索设备完成后直接筛选设备并执行连接，所以这里增加一个获取可用设备和连接设备合并的方法
open fun autoConnectDevice(
before: (()->Unit)? = null, // 前置准备
searchCondition: (()->Boolean), // 获取设备前置条件
search: suspend ()->MutableList?, // 获取设备
filtrationDevice:(MutableList?)->T, // 过滤设备
connectionCondition: ()->Boolean, // 连接设备
connectDevice:(T)->Boolean,
success: (()->Unit)?=null, // 成功
fail: (()->Unit)?=null, // 失败
){
GlobalScope.launch(Dispatchers.IO) {
before?.let { it.invoke() }
val devices = getDevicesWithCondition(condition = searchCondition, search = search)
devices?.let {
val device = filtrationDevice(it)
connectDeviceWithCondition(device, condition = connectionCondition, connectWithTransfer = connectDevice, success = success, fail = fail)
}
}
} 方法分析：若定义了前置准备工作则执行，后续执行前文的获取可用设备方法并筛选出目标设备再进行连接设备操作
2.5.4 子类需实现的抽象方法
connect(device:Any)：连接设备
disconnect()：断开连接
getDevices()：获取可用设备
除了以上三个基本操作以外还有两个程序比较常用的操作
initDevice()：每次在连接设备之后需要下发一些列的初始化指令和其他一系列初始化工作
sendMessage(targetCardNumber:String, type:Int, content_str:String)：发送北斗消息，这也是最常用的功能之一并且根据设备种类的不同所需下发的协议也有所不同
完整基类
abstract class BaseConnector {
var TAG = "BaseConnector"
var isConnected = false // 连接状态
companion object{
var connector:BaseConnector? = null // 全局唯一连接器
@JvmName("setConnectorJava")
fun setConnector(connector: BaseConnector?){
this.connector = connector
}
}
abstract fun connect(device:Any) // 连接设备
abstract fun disconnect() // 断开连接
abstract suspend fun getDevices():List? // 获取可用设备

){

if(connectWithTransfer(device)){
Log.e(TAG, "设备连接成功" )
success?.let { it.invoke() }
}else{
Log.e(TAG, "设备连接失败" )
fail?.let { it.invoke() }
}
}
// 连接设备（前置条件）

}
}else{

}
}
// 从所有设备的列表中筛选并根据条件自动连接
open fun autoConnectDevice(
before: (()->Unit)? = null, // 前置准备

search: suspend ()->MutableList?, // 获取设备
filtrationDevice:(MutableList?)->T, // 过滤设备

){

devices?.let {
val device = filtrationDevice(it)
connectDeviceWithCondition(device, condition = connectionCondition, connectWithTransfer = connectDevice, success = success, fail = fail)
}
}
}
}
// 获取可用设备列表
open suspend fun getDevicesWithCondition(
before: (()->Unit)?=null,
condition: (()->Boolean),
search: suspend ()->MutableList?,
after: (()->Unit)?=null
): MutableList? {
try {
before?.let { it.invoke() }
if(condition()){
val devices = withContext(Dispatchers.IO){
withTimeout(10*1000){
search()
}
}
return if(devices!=null){
after?.invoke()
devices
}else{
null
}
}else{
Log.e(TAG, "获取设备条件不足！")
return null
}
}catch (e:Exception){
e.printStackTrace()
return null
}
}
} 3. ViewModel
使用的 ViewModel 只有两个
3.1 CommunicationVM
存储联系人和聊天消息记录，主要在选择联系人和聊天页面使用
class CommunicationVM : BaseViewModel() {
private val TAG = "CommunicationVM"
private val contactList : MutableLiveData?> = MutableLiveData() // 联系人列表
private val messageList : MutableLiveData?> = MutableLiveData() // 消息列表
// 获取联系人列表数据
fun getContact() : LiveData?> {
upDateContact()
return contactList
}
fun upDateContact(){
launchUIWithResult(
responseBlock = {
DaoUtils.getContacts()
},
successBlock = {
it?.let { contacts ->
Log.e(TAG, "成功查询到: ${contacts.size} contact" )
contactList.value = contacts
}
}
)
}
fun getMessage(number:String) : LiveData?> {
upDateMessage(number)
return messageList
}
fun upDateMessage(number:String){
launchUIWithResult(
responseBlock = {
DaoUtils.getMessages(number)
},
successBlock = {
it?.let { messages ->
Log.e(TAG, "成功查询到: ${messages.size} messages" )
messageList.value = messages
// 清除未读消息数量
DaoUtils.getInstance().clearContactUnread(number)
}
}
)
}
} 3.2 MainVM
存储设备连接状态、实时设备参数等全局使用的变量
class MainVM : BaseViewModel() {
val TAG = "MainVM"
val isConnectDevice : MutableLiveData = MutableLiveData() // 是否连接设备
val deviceCardID : MutableLiveData = MutableLiveData() // 卡号
val deviceCardFrequency : MutableLiveData = MutableLiveData() // 频度
val deviceCardLevel : MutableLiveData = MutableLiveData() // 通信等级
val deviceBatteryLevel : MutableLiveData = MutableLiveData() // 电量
val signal : MutableLiveData = MutableLiveData() // 信号
val deviceLongitude : MutableLiveData = MutableLiveData() // 设备经度
val deviceLatitude : MutableLiveData = MutableLiveData() // 设备纬度
val deviceAltitude : MutableLiveData = MutableLiveData() // 设备高度
val waitTime : MutableLiveData = MutableLiveData() // 等待时间
val unreadMessageCount : MutableLiveData = MutableLiveData() // 总未读消息数量
val systemLongitude : MutableLiveData = MutableLiveData() // 系统经度
val systemLatitude : MutableLiveData = MutableLiveData() // 系统纬度
val systemAltitude : MutableLiveData = MutableLiveData() // 系统高度
init {
initDeviceParameter()
initSystemParameter()
}
// 初始化默认参数
fun initDeviceParameter(){
isConnectDevice.postValue(false)
deviceCardID.postValue("-")
deviceCardFrequency.postValue(-1)
deviceCardLevel.postValue(-1)
deviceBatteryLevel.postValue(-1)
signal.postValue(intArrayOf(0,0,0,0,0,0,0,0,0,0))
waitTime.postValue(0)
deviceLongitude.postValue(0.0)
deviceLatitude.postValue(0.0)
deviceAltitude.postValue(0.0)
}
fun initSystemParameter(){
systemLongitude.postValue(0.0)
systemLatitude.postValue(0.0)
systemAltitude.postValue(0.0)
}
// 当前信号是否良好
fun isSignalWell():Boolean{
if(isConnectDevice.value==false){return false}
val max_single = Arrays.stream(signal.value).max().orElse(0) // 拿到所有信号中的最大值
return max_single>40 // 大于40可发消息
}
fun getUnreadMessageCount() : LiveData {
upDateUnreadMessageCount()
return unreadMessageCount
}
fun upDateUnreadMessageCount(){
launchUIWithResult(
responseBlock = {
DaoUtils.getContacts()
},
successBlock = {
// 计算未读消息数量
it?.let { contacts ->
var count = 0
contacts.forEach { contact ->
if(contact.unreadCount>0){
count += contact.unreadCount
}
}
unreadMessageCount.value = count
}
}
)
}
private var countDownJob: Job? = null
fun startCountDown(){
if(deviceCardFrequency.value==-1){return}
val frequency = deviceCardFrequency.value!!.plus(2) // 总倒计时：频度+2秒
countDownJob = countDownCoroutines(frequency, viewModelScope,
onTick = { countDownSeconds ->
waitTime.postValue(countDownSeconds)
},
onStart = {},
onFinish = {countDownJob?.cancel()}
)
}
} 2. 基本功能实现
1. 页面跳转
项目使用路由框架实现页面跳转功能，整个项目中需要根据条件跳转至不同页面的地方只有一处，所以没有专门设置拦截事件，使用最基本的跳转功能即可满足需求
定义路由路径常量
// 路由路径 ---------------------------------------------------------
public static final String MESSAGE_ACTIVITY = "/main/activity/message";
public static final String STATE_ACTIVITY = "/main/activity/state";
public static final String MAP_ACTIVITY = "/main/activity/map";
public static final String HEALTHY_ACTIVITY = "/main/activity/healthy";
public static final String SOS_ACTIVITY = "/main/activity/sos";
public static final String SETTING_ACTIVITY = "/main/activity/setting";
public static final String VOICE_AUTH_ACTIVITY = "/main/activity/setting/voice_auth";
public static final String COMPRESSION_RATE_ACTIVITY = "/main/activity/setting/compression_rate";
public static final String PLATFORM_SETTING_ACTIVITY = "/main/activity/setting/platform_setting";
public static final String SWIFT_MESSAGE_ACTIVITY = "/main/activity/setting/swift_message";
public static final String ABOUT_US_ACTIVITY = "/main/activity/setting/about_us";
public static final String COMMUNICATION_LINK_ACTIVITY = "/main/activity/setting/communication_link";
public static final String CONNECT_BLUETOOTH_ACTIVITY = "/main/activity/connect_bluetooth";
public static final String CONNECT_USB_HOST_ACTIVITY = "/main/activity/connect_usb_host";
public static final String CONNECT_USB_ACCESSORY_ACTIVITY = "/main/activity/connect_usb_accessory";
public static final String CONNECT_SERIAL_PORT = "/main/activity/connect_serial_port";页面编写完成后注册路由路径
@Route(path = Constant.MESSAGE_ACTIVITY)
class MessageActivity : BaseMVVMActivity(false) 页面跳转
// 直接跳转
ARouter.getInstance().build(Constant.COMMUNICATION_LINK_ACTIVITY).navigation()
// 带参跳转
ARouter.getInstance().build(Constant.COMMUNICATION_LINK_ACTIVITY).withInt("mode",0).navigation()2. 通信链路
