【移动应用开发技术】android中怎么利用ARouter实现组件化

这篇文章给大家介绍android中怎么利用ARouter实现组件化，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。工程目录:/admin/fckeditor/editor/工程一共分为4个模块，基础组件app、基础服务（包涵路由服务）basecommonlibrary模块、业务模块libraryone、业务模块librarytwo;在4个模块的gradle文件当中加入如下代码：android

{

...

defaultConfig

{

...

javaCompileOptions

{

annotationProcessorOptions

{

arguments

=

[moduleName:

project.getName()]

}

}

}

}

dependencies

{

...

compile

'com.alibaba:arouter-api:1.2.1'

annotationProcessor

'com.alibaba:arouter-compiler:1.1.2'

}依赖包的具体版本可自行选择。接下来就是具体讲解ARouter如何在这几个模块中充当路由的角色了。首先是app模块中定义的一个页面，布局很简单，就不贴代码了，效果如下；Activity部分代码如下：@Override

public

void

onClick(View

v)

{

switch

(v.getId())

{

case

R.id.bt1:

RouterCommonUtil.startMainTextActivity(this,

"测试文本");

break;

case

R.id.bt2:

RouterCommonUtil.startMainImageActivity(this,

"/timg?image&quality=80&size=b9999_10000&sec=1492584424522&di=5dcde77431914e0b944b8af9ff5f9277&imgtype=jpg&src=http%3A%2F%2F%2Fit%2Fu%3D1489971249%2C1618541505%26fm%3D214%26gp%3D0.jpg");

break;

case

R.id.bt3:

RouterCommonUtil.startLibraryOneActivity(this);

break;

case

R.id.bt4:

RouterCommonUtil.startLibraryTwoActivity(this);

break;

}

}

@Override

protected

void

onActivityResult(int

requestCode,

int

resultCode,

Intent

data)

{

super.onActivityResult(requestCode,

resultCode,

data);

if

(resultCode

==

1002)

{

Toast.makeText(this,

data.getStringExtra("arg2"),

Toast.LENGTH_SHORT).show();

}

}点击事件分别响应到本module（app）中的两个activity以及libraryone和librarytwo中的activity，其中第一个用来测试ForResult方式启动的Acitivty。接下来是libraryone中Activity布局截图：activity部分代码如下：@Override

public

void

onClick(View

v)

{

int

i

=

v.getId();

if

(i

==

R.id.bt1)

{

RouterCommonUtil.startMainActivity(this);

}

else

if

(i

==

R.id.bt2)

{

RouterCommonUtil.startLibraryTwoActivity(this);

}

}也是测试了两个跳转，分别跳转到主Module中的Activity中和libraryTwo的Activity中，libraryTwo中的布局和代码跟libraryone中大同小异，这里就不继续贴出了，本项目会在附件中提供源码，欢迎下载。这里还需要贴出封装在basecommonlibrary模块中的公共跳转类，所有的module，都是通过该模块中的路由公共类来实现跳转的，完整代码如下:import

android.app.Activity;

import

android.text.TextUtils;

import

android.widget.Toast;

import

com.alibaba.android.arouter.facade.Postcard;

import

com.alibaba.android.arouter.launcher.ARouter;

import

com.example.basecommonlibrary.router.IInterceptor.InterruptCallback;

import

rx.Observable;

import

rx.Subscriber;

import

rx.android.schedulers.AndroidSchedulers;

import

rx.functions.Action1;

public

class

RouterCommonUtil

{

static

void

toastInterruptInfo(final

activity,

final

Postcard

postcard)

{

if

(postcard.getTag()

!=

null

&&

postcard.getTag()

instanceof

String)

{

Observable.create(new

Observable.OnSubscribe<String>()

{

@Override

public

void

call(Subscriber<?

super

subscriber)

{

subscriber.onNext((String)

postcard.getTag());

}

}).observeOn(AndroidSchedulers.mainThread()).subscribe(new

Action1<String>()

{

@Override

public

void

call(String

s)

{

if

(!TextUtils.isEmpty(s)

&&

activity

!=

null)

{

Toast.makeText(activity,

(String)

postcard.getTag(),

Toast.LENGTH_SHORT).show();

}

}

});

}

}

public

static

void

startMainActivity(final

Activity

activity)

{

ARouter.getInstance().build("/ui/主页").navigation(activity,

new

InterruptCallback()

{

@Override

public

void

onInterrupt(Postcard

postcard)

{

toastInterruptInfo(activity,

postcard);

}

});

}

public

static

void

startMainTextActivity(final

Activity

activity,

String

value)

{

ARouter.getInstance().build("/ui/text",

"文本").withString("arg1",

value).navigation(activity,

1001,

new

InterruptCallback()

{

@Override

public

void

onInterrupt(Postcard

postcard)

{

toastInterruptInfo(activity,

postcard);

}

});

}

public

static

void

startMainImageActivity(final

Activity

activity,

String

value)

{

ARouter.getInstance().build("/ui/image",

"图片").withString("arg1",

value).navigation(activity,

new

InterruptCallback()

{

@Override

public

void

onInterrupt(Postcard

postcard)

{

toastInterruptInfo(activity,

postcard);

}

});

}

public

static

void

startLibraryOneActivity(final

Activity

activity)

{

ARouter.getInstance().build("/libraryOne/主页").navigation(activity,

new

InterruptCallback()

{

@Override

public

void

onInterrupt(Postcard

postcard)

{

toastInterruptInfo(activity,

postcard);

}

});

}

public

static

void

startLibraryTwoActivity(final

Activity

activity)

{

ARouter.getInstance().build("/libraryTwo/主页").navigation(activity,

new

InterruptCallback()

{

@Override

public

void

onInterrupt(Postcard

postcard)

{

toastInterruptInfo(activity,

postcard);

}

});

}

}该类中主要提供了几个类的跳转方法，以及跳转失败后的信息打印方法，接下来就是测试跳转是否能够正常执行了，请大家自行构建代码或者下载本demo源码查看执行效果。接下来讲解拦截器，以libraryone中的activity为例@Route(path

=

"/libraryOne/主页",

extras

=

CommonStation.CHECK_LOADING)我们在activity上添加如上注解，其中extras的值可以作为判断的类型，具体看拦截器代码import

android.content.Context;

import

com.alibaba.android.arouter.facade.Postcard;

import

com.alibaba.android.arouter.facade.annotation.Interceptor;

import

com.alibaba.android.arouter.facade.callback.InterceptorCallback;

import

com.alibaba.android.arouter.facade.template.IInterceptor;
