小编MXF*_*MXF的帖子

我有这个功能

        val client = NetworkService()
        val call = client.getService().getAllPost()
        call.enqueue(object : Callback<ArrayList<Post>>{
            override fun onFailure(call: Call<ArrayList<Post>>, t: Throwable) {
                Toast.makeText(this@MainActivity, "Get post failed", Toast.LENGTH_LONG).show()
            }

            override fun onResponse(
                call: Call<ArrayList<Post>>,
                response: Response<ArrayList<Post>>) {
                response.body()?.let{
                    post ->
                    adapter?.updateData(post)
                }?: kotlin.run {
                    Toast.makeText(this@MainActivity, "Get post failed", Toast.LENGTH_LONG).show()
                }

            }

        })

    }

*并有错误*

Type mismatch: inferred type is <no name provided> but Callback<Post!>! was expected

在call.enqueue(object : Callback<ArrayList<Post>> 回调 ArrayList 中不想使用对象，不知道为什么

请帮忙这个

我尝试在一个协程中初始化三个收集，但仅第一个起作用。仅当我设置在不同的协程中收集其工作时。为什么？

  lifecycleScope.launch {
            launch {
                homeViewModel.dateStateFlow().collect { date ->
                    date?.let { calendar.text = date.toStringForView() }
                }
            }
            launch {
                homeViewModel.toStateFlow().collect { to ->
                    to?.let { cityTo.text = to.name }
                }
            }
            launch {
                homeViewModel.fromStateFlow().collect { from ->
                    from?.let { cityFrom.text = from.name }
                }
            }
        }
