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 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;
}

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

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 {
....
}

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);
  ......
   
}

带对象跳转 定义解析类

    @Route(path = "/signing/json")
public class JsonSerializationService implements SerializationService {
    Gson gson;
    @Override
    public <T> T json2Object(String input, Class<T> clazz) {
        return gson.fromJson(input,clazz);
    }
    @Override
    public String object2Json(Object instance) {
        return gson.toJson(instance);
    }
    @Override
    public <T> 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);

通过uri跳转 AndroidManifest文件的Activity节点下配置

 <intent-filter>
    <data
    android:host="ideal.com"
    android:scheme="test"/>
    <action android:name="android.intent.action.VIEW"/>
    <category android:name="android.intent.category.DEFAULT"/>
    <category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>

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{
 ....
}

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
}

});

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) {

  }
}

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

页面跳转动画

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

跳过所有的拦截器

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