EasyRouter

欢迎加入Android技术交流群,群号码:577953847

EasyRouter是一个简易的使用字符串进行Activity,Browser跳转的路由框架,并支持组件化开发。

Features

  • EasyRouter实现了通过字符串进行Activity之间跳转路由,通过APT在编译器实现路由表的构建,劫持了startActivity()进行动态路由
  • EasyRouter实现了Activity之间跳转,返回时的数据自动注入,完全屏蔽了原生的一套繁琐API
  • EasyRouter实现了通过字符串进程Browser的路由跳转
  • EasyRouter支持更换路由跳转时数据序列化的解析器,默认为Gson,可以通过EasyRouterSet进行更换
  • EasyRouter劫持了onActivityResult(),并将其改为接口回调
  • EasyRouter通过transform+ASM实现了一个gradle插件来支持组件化开发

Usage

1.在Activity中自定义URL标识符,目前只支持单一的URL标识,URL的Scheme均为activity://

@Route("activity://main")
public class MainActivity extends AppCompatActivity {
}

2.在Application中进行初始化

EasyRouter.init(this);

3.跳转

  • Activity之间无参数传递跳转
Message message = new MessageBuilder().setAddress("activity://two").build();
EasyRouter.route(MainActivity.this, message);
  • Activity之间有参数传递跳转
Message message = new MessageBuilder()
                        .setAddress("activity://two")
                        .addParam("data", "haha", String.class)
                        .addParam("person", new Person(21, "Zane"), Person.class)
                        .build();
EasyRouter.route(MainActivity.this, message);

被启动Activity需要用@Param标记参数变量

@Route("activity://two")
public class ActivityTwo extends AppCompatActivity{

    @Param("data")
    public String data;
    @Param("person")
    public Person person;
}
  • Activity需要回调的启动(startActivityForResult())
Message message = new MessageBuilder()
                               .setAddress("activity://two")
                               .addParam("data", "haha", String.class)
                               .addParam("person", new Person(21, "Zane"), Person.class)
                               .build();
EasyRouter.routeForResult(MainActivity.this, message, new OnActivityResultListener() {
          @Override
          public void onActivityResult(int resultCode, Intent data) {
                //dosomething
          }
});

如果有返回的数据,需要通过@Result标记返回参数变量

@Route("activity://main")
public class MainActivity extends AppCompatActivity {

    @Result("result_three")
    public String resultThree;
    @Result("result_two")
    public String resultTwo;
}
  • Activity的setResult()
EasyRouter.setResult(ActivityTwo.this, 0, new MessageBuilder()
                                                   .addParam("result_two", "data from two", String.class)
                                                   .build());
finish();
  • Web页面跳转
EasyRouter.route(MainActivity.this, new MessageBuilder()
                                             .setAddress("http://xzane.cc")
                                             .build());
  • 更改数据序列化的工具

首先需要实现一个序列化工具的工厂类,可以参考框架中的GsonConvertFactory

EasyRouterSet.setConverterFactory(GsonConventerFactory.creat());

Principle

  • 使用动态代理生成Instrumentation代理类并通过反射替换ActivityThread中的Instrumentation变量,劫持execStartActivity()方法达到动态查找路由表并进行跳转的效果
  • 所有的参数注入代码以及路由表的代码生成均通过APT在编译期完成
  • onActivityResult方法的劫持是通过生成无View的Fragment达到的,借鉴了RxPermission
  • 通过registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback)去劫持所有Activity的onCreat()方法
  • 编译期通过transform获取编译产物,使用ASM进行AOP操作融合application和library的路由表

Dependency

  • 在Project build.gradle中
allprojects {
 repositories {
    maven { url "https://jitpack.io" }
 }
}
  • 在Application build.gradle中
dependencies {
    compile 'com.github.Zane96.EasyRouter:router:v1.1.1'
    annotationProcessor 'com.github.Zane96.EasyRouter:easyrouter-compiler:v1.1.1'
}
  • 如果您希望支持Android组件化开发,那么还需要在Project的build.gradle中添加如下依赖:
buildscript {
    dependencies {
        classpath 'com.zane:easyrouterMerge:1.0.0'
    }
}

并在Application和Library的build.gradle中均添加如下插件:

apply plugin: 'me.zane.easyrouter-merge'

TODO

  • 返回数据,自动注入
  • 请求报文实体类封装,Builder类生成URL,头部,数据body
  • 支持组件化开发
  • 跳转时候的参数应该不依赖key的值,要自动或者手动注入
  • 地址做成多个
