Activity页面传值基本类型、集合、对象，以及回退接收

Activity-Activity

序列化
传值类型为对象、集合都需要序列化

data class Person(var name: String, var age:Int,) : Serializable {
}

页面传值-Activity1向Activity2传值

Activity1页面跳转时传值

  openActivity(Activity2::class.java,Bundle().apply {
                        putSerializable("person", person)
                        putInt("valueInt", 123)
                        putString("valueString", "字符串")
                    })

Activity2页面创建前接收

  @Param
    lateinit var person: Person

    @Param
    var valueInt = 0

    @Param
    var valueString = ""

回退接收-Activity2回退到Activity1并向其传值

Activity2传值

 LiveEventBus
            .get("some_key")
            .post(person)

Activity1接收

LiveEventBus
            .get("some_key", Person::class.java)
            .observe(this){
                binding.etValue.setText(it.age.toString())}
