Android Fragment中使用Arouter跳转到Activity后返回Fragment不回调onActivityResult

Fragment中通过路由跳转到Activity

跳转传递参数

通过Arouter跳转

Postcard postcard = ARouter.getInstance().build(RouterConstant.ACTION_TRANSMANAGERACTIVITY1);
Bundle bundle = new Bundle();
bundle.putInt("code", 404);
postcard.with(bundle); //设置bundle
fragmentNavigation(postcard,10000);


private void fragmentNavigation(Postcard postcard , int requestCode) { 
    LogisticsCenter.completion(postcard);
    Intent intent = new Intent(getActivity(),postcard.getDestination());
    intent.putExtras(postcard.getExtras());
    startActivityForResult(intent, requestCode);
}

Activity中获取参数

  ARouter.getInstance().inject(this);
  num =  getIntent().getExtras().getInt("code");

注意传递的参数Bundle也可以如下传递Bundle参数

设置Bundle参数

postcard.withBundle("Bundle",bundle);

Activity中获取Bundle参数

getIntent().getBundleExtra("Bundle").getInt("code");

在Activity中返回时别忘记了设置结果或者参数：

setResult(Activity.RESULT_OK);

Fragment总就可以重写onActivityResult方法，在此方法获取上一个Activity返回来的数据了或者处理相关业务逻辑了；

注意onActivityResult方法中int requestCode, int resultCode的区别；
