Android路由框架Router分析详解

 public class App extends MultiDexApplication {
   @Override
   public void onCreate() {
     super.onCreate();
     // 初始化
     Router.initialize(this);
     // 开启log
     if (BuildConfig.DEBUG) {
       Router.openLog();
     }
   }
 }

 // 单路径注解
 @Route("test")
 public class TestActivity extends Activity {
 ...
 }

 // 多路径注解，这几个注解都能打开该Activity
 @Route({"user", "example://user", "http://example.com/user"})
 public class UserActivity extends Activity {
 ...
 }

 // 最简单的路由跳转，打开TestActivity
 Router.build("test").go(context);

 // 其他部分api
 Router.build("user")
   .requestCode(int) // 调用startActivityForResult
   .extras(bundle) // 携带跳转参数
   .addFlags(flag) // 添加标记，比如intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
   .anim(enter, exit) // 添加跳转动画
   .callback(calback) // 跳转结果回调
   .go(context);

// 动态添加路由
Router.addRouteTable(new RouteTable() {
  @Override
  public void handleActivityTable(Map<String, Class<? extends Activity>> map) {
    map.put("dynamic", DynamicActivity.class);
  }
});

Router.addRouteInterceptor(new RouteInterceptor() {
  @Override
  public boolean intercept(Context context, @NonNull Uri uri, @Nullable Bundle extras) {
    // operation.
    return false;
  }
});

// 返回true表示当前路由被该Matcher匹配，返回false则会继续匹配其他Matcher
public abstract boolean match(Context context, Uri uri, @Nullable String route, RouteOptions routeOptions);

// match方法返回true后会调用该方法，用来生成一个Intent对象
public abstract Intent onMatched(Context context, Uri uri, @Nullable Class<? extends Activity> target);
