ARouter的简单使用

依赖

implementation 'com.alibaba:arouter-api:1.3.1'
annotationProcessor 'com.alibaba:arouter-compiler:1.1.4'

android-defaultConfig节点下添加,用到Arouter的都要添加，组件也要添加

javaCompileOptions {
     annotationProcessorOptions {
         arguments = [AROUTER_MODULE_NAME: project.getName()]
     }
}

初始化

1. 在Application中初始化SDK

   private void initARouter() { if (isDebug()) { // 这两行必须写在init之前，否则这些配置在init过程中将无效 ARouter.openLog(); // 打印日志 ARouter.openDebug(); // 开启调试模式(如果在InstantRun模式下运行，必须开启调试模式！线上版本需要关闭,否则有安全风险) } ARouter.init(this); // 尽可能早，推荐在Application中初始化 }

   public boolean isDebug() { return debug; }

2. 混淆设置

   -keep public class com.alibaba.android.arouter.routes.{*;} -keep public class com.alibaba.android.arouter.facade.{;} -keep class * implements com.alibaba.android.arouter.facade.template.ISyringe{;} -keep interface * implements com.alibaba.android.arouter.facade.template.IProvider

基本使用

1. 不带参跳转

• 跳转页面，使用build设置要跳转的path

  ARouter.getInstance().build("/signing/main").navigation();

• 目标页面,使用@Route注解设置path

  @Route(path = "/signing/main") public class SigningActivity extends AppCompatActivity { .... }

1. 带参跳转

• 跳转页面,使用withXXX来设置要传递的参数，此处用法和intent类似

  ARouter.getInstance().build(ArouterConstan.SIGNING_MAIN) .withString("path", path) .navigation();

• 目标页面

第一种与第二种需要配合 ARouter.getInstance().inject(this);使用，在oncreate中调用

//第一种,指定name，变量名就可以随便定义了
@Autowired(name = "path")
private String path_alias;

//第二种，不指定名称，变量名要与key相同
@Autowired()
private String path;

//第三种
private String in_path = getIntent.getExtras().getString("path");

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signing);
    ARouter.getInstance().inject(this);
  ......

}

1. 带对象跳转

• 定义解析类

  @Route(path = "/signing/json") public class JsonSerializationService implements SerializationService { Gson gson; @Override public T json2Object(String input, Class clazz) { return gson.fromJson(input,clazz); } @Override public String object2Json(Object instance) { return gson.toJson(instance); } @Override public T parseObject(String input, Type clazz) { return gson.fromJson(input,clazz); } @Override public void init(Context context) { gson = new Gson(); } }

• 跳转页面

  FileInfo fileInfo = new FileInfo(); ARouter.getInstance().build(ArouterConstan.SIGNING_MAIN) .withString("path", path) .withObject("obj",fileInfo) .navigation();

• 目标页面

  SerializationService serializationService = ARouter.getInstance().navigation(JsonSerializationService.class); serializationService.init(this); FileData obj = serializationService.parseObject(getIntent().getStringExtra("obj"), User.class);

1. 通过uri跳转

• AndroidManifest文件的Activity节点下配置

• 跳转页面

  Uri uri = Uri.parse("test://ideal.com/signing/main"); ARouter.getInstance().build(uri).navigation();

• 目标页面

  @Route(path = "/signing/main") public class SigningActivity extends AppCompatActivity{ .... }

1. 跳转回调

   ARouter.getInstance().build(uri).navigation(this, new NavCallback() { @Override public void onInterrupt(Postcard postcard) { super.onInterrupt(postcard); //被拦截了 }

   @Override
   public void onArrival(Postcard postcard) {
       //正常交还控制权
   }
   

   });

2. 跳转拦截

   @Interceptor(priority = 8, name = "test interceptor") public class TestInterceptor implements IInterceptor { @Override public void process(Postcard postcard, InterceptorCallback callback) {

     //两者一定要调用一个
       callback.onContinue(postcard);  
       // callback.onInterrupt(new RuntimeException("Something exception"));      
   }
   
   @Override
   public void init(Context context) {
   
   }
   

   }

3. startActivityForResult模式

   ARouter.getInstance().build("/home/main").navigation(this, 5); //第一个参数必须是Activity，第二个参数是requestCode

4. 页面跳转动画

   ARouter.getInstance() .build("/signing/main") .withTransition(R.anim.activity_in, R.anim.activity_out) .navigation(this);

5. 跳过所有的拦截器

   ARouter.getInstance().build("/signing/main").greenChannel().navigation();
