规划驾车路线和途径点及判断车辆路线偏移

2020-02-24 18:48:34

参考地址规划驾车路线和途径点及判断车辆路线偏移

仅供参考，我还是推荐用矩形判断，嘿嘿。

star: 项目需求需要利用百度地图构建路线并支持设置途径点，以及可以实时监控车辆是否偏移路线；两种方案。

写了比较完整的注释了，替换ak可直接看效果，规划驾车路线和途径点及判断车辆路线偏移源码：

当你写爬虫抓不到APP请求包的时候该怎么办？
提示：因为高级篇以后的APP将无法使用很通用的方式处理，每种类型甚至是每个APP的反抓包处理方式都会有差别，所以这个系列以后会以【高级篇-具体类型】的形式来写。

Kotlin Sealed class类详解
Sealed class（密封类）是一个有特定数量子类的类，看上去和枚举有点类似，所不同的是，在枚举中，我们每个类型只有一个对象（实例）；而在密封类中，同一个类可以拥有几个对象。

Dagger2之Kotlin写法

Dagger2使用详解
简单的说，就是一个工厂模式，由Dagger负责创建工厂，帮忙生产instance。遵从Java规范JSR 330，可以使用这些注解。现在不研究Dagger2是如何根据注解去生成工厂的，先来看看工厂是什么东西，理解为什么可以实现了DI(Dependency Injection)，如何创建IoC(Inverse of Control)容器。

dagger.android--Fragment，BaseFragment
1 使用Fragment参数来代替Activity参数 2 使用 @FragmentKey来代替@ActivityKey 3 使用HasFragmentInjector来代替@HasActivityInjector 4 AndroidInjection.inject(Fragment)方法,在Fragment的onAttach()中调用，而不是在onCreate()中 5 Fragment的Module添加位置，和Activity是不同的，它取决于Fragment需要的其他依赖注入

2020-11-22 21:12:30

Dependency Injection with Dagger2,Fragment
標註@Provides的method若有parameter的話，Dagger會找出其擁有的該型態物件來使用。我們在Module內新增了DataModel將其列入Dagger的管理下，接著在provideFactory()增加parameter變成provideFactory(DataModel dataModel)，Dagger就會找出其管理的DataModel給provideFactory使用。

How to use Android Injector for Activity and Fragment objects through New Dagger 2 (with Kotlin)
i added kapt instead of annotationProcessor for kotlin. we dont need to keep annotationProcessor dependency. Also we have to add kotlin-plugin in gradle.

androidx中的lifecycle组件
Lifecycle-aware components生命周期感知组件执行操作，以响应另一个组件生命周期状态的更改，例如Activity和Fragment。这些组件可以帮助您生成更有组织、更容易维护的轻量级代码。
