ARouter是阿里巴巴开源出来的一款android路由框架，github地址为 ： https://github.com/alibaba/ARouter
至于ARouter的诸多好处我就不介绍了，这里主要讲解在项目组件化下，ARouter的一些简单使用
先贴上工程目录:
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, "https://timgsa.baidu.com/timg&＃63;image&quality=80&size=b9999_10000&sec=1492584424522&di=5dcde77431914e0b944b8af9ff5f9277&imgtype=jpg&src=http%3A%2F%2Fimg3.imgtn.bdimg.com%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;
/**

* @Filename:
* @Description:

*/
public class RouterCommonUtil {
private static void toastInterruptInfo(final Activity activity, final Postcard postcard) {
if (postcard.getTag() != null && postcard.getTag() instanceof String) {
Observable.create(new Observable.OnSubscribe() {
@Override
public void call(Subscriber<&＃63; super String> subscriber) {
subscriber.onNext((String) postcard.getTag());
}
}).observeOn(AndroidSchedulers.mainThread()).subscribe(new Action1() {
@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;
import com.example.basecommonlibrary.CommonStation;
/**
* @author: xiewenliang
* @Filename:
* @Description:
* @date: 2017/4/25 15:37
*/
@Interceptor(priority = 1, name = "拦截未登录")
public class TestOneIInterceptor implements IInterceptor {
@Override
public void process(Postcard postcard, InterceptorCallback callback) {
if (postcard.getExtra() == CommonStation.CHECK_LOADING && !CommonStation.checkLoading()) {
callback.onInterrupt(new RuntimeException("账号未登录"));
} else {
callback.onContinue(postcard);
}
}
@Override
public void init(Context context) {
}
}
在拦截器中，可以根据extra属性判断是否是需要拦截的类型，如果需要拦截，则执行callback的onInterrupt方法，并注明拦截原因，可以在路由跳转中提取拦截原因信息并打印。
当然ARouter中其它功能就不再一一介绍了，大家可以自行研究，附源码下载地址：ARouterDemo_jb51.rar
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
