AndRouter

AndRouter is an Android framework used to map urls to activities or actions.

中文设计文档

Android路由框架设计与实现

Features

AndRouter implements activities router, so it only needs to define the activities mapping table and enjoy using url to open activities.
AndRouter implements Browser router, so it can be used to open a web url. It will use the system browser to open it.
AndRouter supports adding a user-defined router.
RouteManager will use the first router that can open the url in the list to open it. So the router added earlier will have higher priority.
The default scheme of activities router is "activity", and browser router is "http" and "https". It's allowed to change them.
It supports to change the behavior of the default activity router and browser router.
It can only add one object of a router class to the Router, or it will delete the router object that has the same class that you added and add the new one.

Usage

Initialize

It needs to be initialized if you want to use the default activity router and browser router.

Initialize the ActivityRouter

Here are two methods to initialize the ActivityRouter.

Annotation

It supports using Java annotations to map urls to Activities. For example, the code below maps the urls of "activity://second" and "activity://second2" to SecondActivity.

@RouterMap({"activity://second", "activity://second2"})
public class SecondActivity extends Activity {
@Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_second);     } }

And in the Application class of your app, you need to init the ActivityRouter.

public class App extends Application {
@Override     public void onCreate() {         super.onCreate();         Router.initActivityRouter(getApplicationContext());     } }

Initializer class

Or you can use an IActivityRouteTableInitializer implementation to add the activity router table. In the code below, some routes are added. For example, the route "activity://first/:s{name}/:i{age}/birthday" will map to FirstActivity.class. The route consists of four parts. It's recommended to do this in the Application class of your app.

Router.initActivityRouter(getApplicationContext(), new IActivityRouteTableInitializer() {
            @Override
            public void initRouterTable(Map<String, Class<? extends Activity>> router) {
            		// only if the host is equal and pathes match, it matches.
            		// The url "activity://first/kris/26/birthday" is one of the matches. "kris" and 26 are values of key "name" and "age". and the "name" value type is string, the age value type is integer.
            	   router.put("activity://first/:s{name}/:i{age}/birthday", FirstActivity.class); 
                router.put("activity://second/:{name}", SecondActivity.class);  
                router.put("activity://third/home/:i{room1}/printdoor/:s{color}", ThirdActivity.class); 
                router.put("activity://four/buy/:s{name}/:f{price}", FourActivity.class);                           
            }
        });

It supports to use these two methods together.

Initialize the BrowserRouter

The same with ActivityRouter. Do this in Application class.

public class App extends Application {
@Override     public void onCreate() {         super.onCreate();         Router.initBrowserRouter(getApplicationContext());     } }

Definition Of Route Url

Scheme: Normally, define which router to use, the "activity" in the example.
Host: Normally, define where to go, the "first" in the example.
Path: Define key value and path, the "/:s{name}/:i{age}/birthday" in the example. The path segments can be divided into two types. One, the fixed path, such as "birthday", it's fixed. And the value key such as the :s{name}, it defines values in the path. In url, it will be replaced with value. For example, ":s{name}" can be replaced with "kris", and it will be set to the intent extras with putExtra("name", "kris"). Then in the routing activity, the value of "name" can be get with getStringExtra("name"). The table below showes the value key format. ":{}" is essential. And the character after ':' defines the type of the value. If the url mathes but the value type not matches, it will throw RuntimeException, which you should pay attention to.

| key format | :i{key} | :f{key} | :l{key} | :d{key} | :s{key} or :{key} | :c{key} | |:-------: |:--------: | :------:| :------: | :--------: | :-------: | :----:| | type | integer | float | long | double | string | char|

Query parameters: It supports adding some option parameters in the Query parameters. But it will not influence the route match. For example, the url "activity://first/kris/26?wifename=marry" matches to "activity://first/:{name}/:i{age}". Then in the FirstActivity, the value of "wifename" can be got.

Definition of match

If a url matches a route, the url's scheme and host are equal to the route. And the paths except the value key are equal.

Match Examples

If the route is "activity://main/:{name}/feed/:i{page}/list".

Matches:

activity://main/kris/feed/12/list
activity://main/bob/feed/13/list
activity://main/jim/feed/14/list?q=8

Not Matches

hello://main/kris/feed/12/list | scheme not equal
activity://second/kris/feed/12/list | host not equal
activity://main/kris/fed/12/list | path not match
activity://main/kris/12/list | path not match

Useage of Activity Router

open with startActivity(), it matches the route as "activity://second/:{name}"

private void openSecondActivity(){
        Router.open("activity://second/汤二狗");
   }

in the SecondActivity you can get the value of name

public void getTheValueOfName(){
		String name = getIntent().getStringExtra("name")
	}

open with animation

private void openSecondActivityWithVerticalAnim(){
        ActivityRoute activityRoute = (ActivityRoute) Router.getRoute("activity://second/汤二狗");
        activityRoute
                .setAnimation(this, R.anim.infromleft, R.anim.outtoright)
                .open();
    }

open for result

private void openSecondActivityForResult(){
        ActivityRoute activityRoute = (ActivityRoute) Router.getRoute("activity://second/汤二狗");
        activityRoute.withOpenMethodStartForResult(this, 200)
                .open();
    }

add extra parameters

private void openSecondActivityWithExtraValue(){
        Date date = new Date();
        ActivityRoute activityRoute = (ActivityRoute) Router.getRoute("activity://third");
        activityRoute
                .withParams("date", date)
                .open();
    }

you can get the extra parameters in the ThirdActivity

Date date = (Date) getIntent().getSerializableExtra("date");

Usage of Browser Router

And you can use Router to open web url.

Router.open("http://www.baidu.com");

Add your own Router

you can define your own router and route.

private static class TestRouter extends BaseRouter{
@Override         public void open(IRoute route) {             Timber.i(route.getUrl());         }
@Override         public void open(String url) {             Timber.i(url);         }
@Override         public IRoute getRoute(String url) {             return new TestRoute(this, url);         }
@Override         public boolean canOpenTheRoute(IRoute route) {             return (route instanceof TestRoute);         }
@Override         public boolean canOpenTheUrl(String url) {             return TextUtils.equals(UrlUtils.getScheme(url), "test");         }
@Override         public Class<? extends IRoute> getCanOpenRoute() {             return TestRoute.class;         }     }
private static class TestRoute extends BaseRoute {
public TestRoute(IRouter router, String url) {             super(router, url);         }     }

And add it to the RouterManager

Router.addRouter(new TestRouter());

Interceptor

It support interceptor after version 1.2.8. There is a example that intercept url in black list and go to another error page. You can also use it to do the things like going to the login page when users want to do something needing to be logined.

private static final HashMap<String, String> INTERCEPTORBLACKLIST_SET = new LinkedHashMap<>();
	static {
   		INTERCEPTORBLACKLIST_SET.put("http://www.souhu.com", "activity://error");
   		INTERCEPTORBLACKLIST_SET.put("activity://intercepted", "activity://error");
   	}
	Router.setInterceptor(new Interceptor() {
	
	  	@Override
	   public boolean intercept(Context context, String url) {
	   		if(INTERCEPTORBLACKLIST_SET.keySet().contains(url)){
	   			Router.open(context, INTERCEPTORBLACKLIST_SET.get(url));
	    	      return true;
	       }
	    	return false;
	   }
   });

Install

In the build.gradle file of your project. You need to:

Add dependeny to apt:

buildscript {
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

Add jitpack repository:

allprojects {
 repositories {
    jcenter()
    maven { url "https://jitpack.io" }
 }
}

Then, in the build.gradle file of your app module, you need to add these dependencies.

apply plugin: 'android-apt'

dependencies { compile 'com.github.campusappcn.AndRouter:router:1.2.8' apt 'com.github.campusappcn.AndRouter:compiler:1.2.8' }

Note: do not add the jitpack.io repository under buildscript
