这里的跳转用到了onActivityResult， 使用的是BaseNavigation封装后的方法，第三个参数为是否开启startForResult，第四个参数是标志

封装的方法如下：

fun launch(fromActivity: Activity, intent: Intent? = null) {
  val finalIntent = Intent(fromActivity, route.activityClass)
  paramIntent?.let { finalIntent.putExtras(it) }
  intent?.let { finalIntent.putExtras(it) }
  if (startForResult) {
      fromActivity.startActivityForResult(finalIntent, requestCode, requestBundle)
  } else {
      fromActivity.startActivity(finalIntent)
  }
}

每次跳转都会走到launch函数中

跳转的逻辑写在了ViewModel中，无法调用Acitvity中的setResult和finish方法，因此通过一个liveData传值通知Activity进行相关操作，ViewModel与Activity/Fragments通讯的正确姿势 - 掘金 (juejin.cn)
