XRouter
一种基于Arouter的使用封装方案,实现对ARouter的Retrofit式使用。
ARouter是阿里巴巴开源的Android平台中对页面、服务提供路由功能的中间件,没用过的务必点击传送门
基础功能
1. 依赖配置
android {
defaultConfig {
...
javaCompileOptions {
annotationProcessorOptions {
arguments = [ moduleName : project.getName() ]
}
}
}
}
dependencies {
//ARouter
compile 'com.alibaba:arouter-api:x.x.x'
annotationProcessor 'com.alibaba:arouter-compiler:x.x.x'
//XRouter
compile 'com.mondyxue:xrouter:1.0-SNAPSHOT@aar'
}
repositories {
maven {
//XRouter
url "https://raw.githubusercontent.com/MondyXue/Maven/master"
}
}
2. 给目标页面添加注解
import com.alibaba.android.arouter.facade.annotation.Route;
@Route(path = "/page/browser")
public class WebViewActivity extends BaseActivity{
...
}
3. 在Application中添加初始化代码
//初始化uri信息
XRouter.setScheme("xrouter");
XRouter.setAuthority("mondyxue.github.io");
//XRouter初始化
XRouter.init(DemoApplication.this);
4. 声明Navigator接口
import com.mondyxue.xrouter.annotation.Extra;
import com.mondyxue.xrouter.annotation.Route;
public interface WebNavigator{
@Route(path = "/page/browser")
void openUrl(@Extra("url") String url);
}
5. 发起路由
XRouter.getRouter()
.create(WebNavigator.class)
.openUrl("https://github.com/Alibaba/ARouter");
其它使用
XRouter基于ARouter提供了针对几个常用场景的解决方案
Navigator
a. startActivityForResult
//声明返回类型为ActivityNavigator,T为需要解析的回传数据类型
@Route(path = "/page/login")
ActivityNavigator toLoginFragment();
//复写Activity和Fragment基类中的onActivityResult方法
public abstract class BaseActivity extends FragmentActivity{
...
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
//XRouter处理回调逻辑
XRouter.getRouter()
.getActivityManager()
.onActivityResult(BaseActivity.this, requestCode, resultCode, data);
}
}
//实现Callback
public abstract class UserInfoCallback extends RouteCallback{
@Override public UserInfo parseData(int requestCode, int resultCode, Intent data){
return (UserInfo) data.getSerializableExtra(Extras.UserInfo);
}
}
//路由发起
XRouter.getRouter()
create(DemoNavigator.class)
toLoginFragment()
startActivityForResult(new UserInfoCallback(){
@Override public void onResponse(@NonNull UserInfo data){
Toast.makeText(MainActivity.this, "login success: " + data.toString(), Toast.LENGTH_SHORT).show();
}
});
b. 获取服务
//声明
@Route(path = "/service/userService")
UserService getUserService();
//创建navigator
DemoNavigator navigator = XRouter.getRouter().create(DemoNavigator.class);
//获取UserService
UserService userService = navigator.getUserService();
boolean isLogin = userService.isLogin();
UserInfo userInfo = userService.getUserInfo();
//获取Logger
Logger logger = navigator.getLogger();
logger.e("tag", "msg...");
c. 如果还不满足,继续组合打法
import com.mondyxue.xrouter.navigator.Navigator;
//声明返回类型为Navigator
@Route(path = "/page/login")
Navigator toLoginFragment();
//创建Navigator
Navigator navigator = XRouter.getRouter()
.create(DemoNavigator.class)
.toLoginFragment();
//通过Navigator调用支持方法
Uri uri = navigator.uri();
Intent intent = navigator.intent();
Fragment fragment = navigator.fragment();
IProvider provider = navigator.service();
navigator.startActivity();
RouteType
import com.mondyxue.xrouter.constant.RouteType;
import com.alibaba.android.arouter.facade.annotation.Route;
//在ARouter的Route注解中
//RouteType中有几个辅助flag值,可用于ARouter的Route注解中的extras值Route(extras=...)
RouteType.GreenChannel//绿色通道,不经过拦截器
RouteType.Fragment//Fragment标记
RouteType.Activity//Activity标记
RouteType.Service//标记是否为实现了IProvider的服务类
RouteType.WithinTitlebar//标记此页面是否已有标题栏(Toolbar等)
RouteType.Login//标记访问此页面是否需要登录权限
RouteType.Main//标记此页面是否为App首页
//组合打法
RouteType.TitlebarFragment = Fragment | WithinTitlebar;
RouteType.LoginActivity = Activity | Login;
1. 登录拦截
a. 配置extras标记
@Route(path = "/page/userInfo", extras = RouteType.LoginFragment)
public class UserInfoFragment extends BaseFragment{
...
}
b. 实现登录拦截器
@Interceptor(priority = 4, name = "LoginInterceptor")
public class LoginInterceptor extends com.mondyxue.xrouter.interceptor.LoginInterceptor implements IInterceptor{
//返回当前用户是否已登录
@Override public boolean isLogin(){
return XRouter.getRouter()
.create(DemoNavigator.class)
.getUserService()
.isLogin();
}
//调用登录服务,在登录回调中执行原拦截器回调
@Override protected void onInterrupt(final Postcard postcard, final InterceptorCallback callback){
XRouter.getRouter()
.create(DemoNavigator.class)
.toLoginFragment()
.startActivityForResult(new UserInfoCallback(){
@Override public void onResponse(@NonNull UserInfo data){
postcard.withSerializable(Extras.UserInfo, data);
callback.onContinue(postcard);
}
@Override public void onError(Throwable throwable){
callback.onInterrupt(throwable);
}
@Override public void onCancel(){
callback.onInterrupt(new RuntimeException("login cancel!"));
}
});
}
}
2. Fragment拦截
a. 配置extras标记
@Route(path = "/page/text", extras = RouteType.Fragment)
public class TextFragment extends BaseFragment{
...
}
b. 配置Fragment容器Activity
@Route(path = "/page/contanier", extras = RouteType.Activity | RouteType.GreenChannel)
public class ContanierActivity extends BaseActivity{
@Override protected int getRootLayout(){
//RouteType.Titlebar标记值可通过此方式获取
boolean withinTitlebar = getIntent().getBooleanExtra(RouteExtras.WithinTitlebar, false);
//根据标记值决定容器的布局是否有标题栏
return withinTitlebar ? R.layout.activity_contanier
: R.layout.activity_contanier_within_titlebar;
}
@Override protected void init(){
Intent intent = getIntent();
boolean withinTitlebar = intent.getBooleanExtra(RouteExtras.WithinTitlebar, false);
if(!withinTitlebar){
//判断并设置Title
String title = intent.getStringExtra(RouteExtras.Title);
((TextView) findViewById(R.id.tv_title)).setText(title);
}
//获取拦截器中传过来的Fragment路由path
String path = intent.getStringExtra(RouteExtras.PathTo);
if(!TextUtils.isEmpty(path)){
//使用XRouter根据path获取fragment实例
final Fragment fragment = XRouter.getRouter().build(path).navigator().fragment();
if(fragment != null){
fragment.setArguments(intent.getExtras());
runOnUiThread(new Runnable(){
@Override public void run(){
getSupportFragmentManager()
.beginTransaction()
.add(R.id.fl_contanier, fragment)
.hide(fragment)
.show(fragment)
.commitAllowingStateLoss();
}
});
return;
}
}
finish();
}
}
c. 实现Fragment拦截器
@Interceptor(priority = 8, name = "FragmentInterceptor")
public class FragmentInterceptor extends com.mondyxue.xrouter.interceptor.FragmentInterceptor implements IInterceptor{
@Override protected String getFragmentContainerPath(){
//返回Fragment容器Activity路径
return "/page/contanier";
}
}
还有个MainIntercepter,可用于主界面(RouteType.Main)的跳转拦截,详见Demo代码
混淆
如果你使用混淆并且用到Fragment拦截器的话,需要在混淆配置中添加以下规则:
#XRouter:使用Fragment拦截器
-keep class com.alibaba.android.arouter.facade.Postcard{*;}
后话
小弟不才,第一次分享代码到Github,码代码这茬,一个人容易出事,而且项目来不及写注释,所以特此贴上Q群二维码,如果大家有什么建议和槽点,欢迎能够多多交流。
