通过Scheme跳转
Scheme是界面跳转协议，类似URL地址，通过url可以打开某个网站，而通过Scheme可以打开app的某个界面。常用在推送、H5跳转到APP某个界面
Aroute也是支持Scheme跳转。
使用

配置Scheme协议类
<activity android:name=".ui.SchemeActivity" >
<!-- Scheme -->
<intent-filter>
<data
android:host="m.aliyun.com"
android:scheme="arouter"/>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>
<!-- App Links -->
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data
android:host="m.aliyun.com"
android:scheme="http"/>
<data
android:host="m.aliyun.com"
android:scheme="https"/>
</intent-filter>
</activity>
获取Scheme内容通过Aroute跳转
class SchemeActivity:AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val uri = intent.data
ARouter.getInstance().build(uri).navigation(this,object : NavCallback(){
override fun onArrival(postcard: Postcard?) {
println(postcard.toString())
}
})
finish()
}
}
目标页中获取参数
@JvmField
@Autowired(desc = "姓名")
var name = "jack"
@JvmField
@Autowired
var age = 10
@JvmField
@Autowired
var height = 175
@JvmField
@Autowired(name = "boy", required = true)
var girl = false
拦截器
@Interceptor(priority = 7,name = "测试拦截器")
class TextInterceptor : IInterceptor {
override fun process(postcard: Postcard?, callback: InterceptorCallback?) {
val mDialog by lazy { AlertDialog.Builder(postcard?.context) }
if (RoutePath.Main.PAGE_INTERCEPTOR_ACTIVITY == postcard?.path) {
mDialog.apply {
setTitle("拦截器")
setNegativeButton("继续"
) { _, _ ->
callback?.onContinue(postcard)
}
setNeutralButton("算了"){
_,_ ->
callback?.onInterrupt(Throwable("我觉得有问题"))
}
setPositiveButton("加点料", object : DialogInterface.OnClickListener {
override fun onClick(dialog: DialogInterface?, which: Int) {
postcard.withString(ArouteKey.MAIN.KEY_DATA, "我是来自拦截器的参数")
callback?.onContinue(postcard)
}
})
}
Handler(Looper.getMainLooper()).post {
mDialog.create().show()
}
}else{
callback?.onContinue(postcard)
}
}
override fun init(context: Context?) {
"${TextInterceptor::class.java.simpleName} has init".e()
}
}
多个拦截器会按优先级顺序依次执行,priority越小先执行
callback?.onContinue(postcard) 继续执行
callback?.onInterrupt(Throwable("我觉得有问题")) 中断路由流程，并回调callback#onInterrupt()
// 以上两种至少需要调用其中一种，否则不会继续路由
postcard.withString(ArouteKey.MAIN.KEY_DATA, "我是来自拦截器的参数")
postcard.path = ...
可以添加参数，或者重新设置path
依赖注入
ARouter.getInstance().build("/test/activity1")
.withString("name", "老王")
.withInt("age", 18)
.withBoolean("boy", true)
.withLong("high", 180)
.withString("url", "https://a.b.c")
.withSerializable("ser", testSerializable)
.withParcelable("pac", testParcelable)
.withObject("obj", testObj)
.withObject("objList", objList)
.withObject("map", map)
.navigation();
目标类通过依赖获取data
//name = key 当值是null可能会carsh
@Autowired(name = "boy", required = true)
boolean girl;
@Autowired
TestSerializable ser;
@Autowired
TestParcelable pac;
@Autowired
TestObj obj;
@Autowired
List<TestObj> objList;
@Autowired
Map<String, List<TestObj>> map;
注意序列化和obj
public class TestSerializable implements Serializable {
public String name;
public int id;
public TestSerializable() {
}
public TestSerializable(String name, int id) {
this.name = name;
this.id = id;
}
}
public class TestObj {
public String name;
public int id;
public TestObj() {
}
public TestObj(String name, int id) {
this.name = name;
this.id = id;
}
}
// 如果需要传递自定义对象，新建一个类（并非自定义对象类），然后实现 SerializationService,并使用@Route注解标注(方便用户自行选择序列化方式)，例如：
@Route(path = "/yourservicegroupname/json")
public class JsonServiceImpl implements SerializationService {
@Override
public void init(Context context) {
}
@Override
public <T> T json2Object(String text, Class<T> clazz) {
return JSON.parseObject(text, clazz);
}
@Override
public String object2Json(Object instance) {
return JSON.toJSONString(instance);
}
}
模块间方法调用
购物车模块想要判断用户是否登录，并且模块间没有依赖。就可以通过暴漏接口获取
Module_base
// 声明接口,其他组件通过接口来调用服务
public interface HelloService extends IProvider {
String sayHello(String name);
}
ModuleA
// 实现接口
@Route(path = "/yourservicegroupname/hello", name = "测试服务")
public class HelloServiceImpl implements HelloService {
@Override
public String sayHello(String name) {
return "hello, " + name;
}
@Override
public void init(Context context) {
}
}
ModuleB
public class Test {
@Autowired
HelloService helloService;
@Autowired(name = "/yourservicegroupname/hello")
HelloService helloService2;
HelloService helloService3;
HelloService helloService4;
public Test() {
ARouter.getInstance().inject(this);
}
public void testService() {
// 1. (推荐)使用依赖注入的方式发现服务,通过注解标注字段,即可使用，无需主动获取
// Autowired注解中标注name之后，将会使用byName的方式注入对应的字段，不设置name属性，会默认使用byType的方式发现服务(当同一接口有多个实现的时候，必须使用byName的方式发现服务)
helloService.sayHello("Vergil");
helloService2.sayHello("Vergil");
// 2. 使用依赖查找的方式发现服务，主动去发现服务并使用，下面两种方式分别是byName和byType
helloService3 = ARouter.getInstance().navigation(HelloService.class);
helloService4 = (HelloService) ARouter.getInstance().build("/yourservicegroupname/hello").navigation();
helloService3.sayHello("Vergil");
helloService4.sayHello("Vergil");
}
}
跳转回调
ARouter.getInstance().build("/xxx/xxx").navigation(this, new NavCallback() {
@Override
public void onFound(Postcard postcard) {
Log.d("ARouter", "找到了");
}
@Override
public void onLost(Postcard postcard) {
Log.d("ARouter", "找不到了");
}
@Override
public void onArrival(Postcard postcard) {
Log.d("ARouter", "跳转完了");
}
@Override
public void onInterrupt(Postcard postcard) {
Log.d("ARouter", "被拦截了");
}
});
