Question

新的Android开发人员，对我轻松一点！我有2级API调用，无法正常工作。我的第一级（设备列表）工作正常，但是当我单击设备以查看详细信息时，什么也没有显示。在日志中，我完全看不到设备详细信息类，并且我不确定为什么。任何帮助表示赞赏。

在设备详细信息类中添加了日志记录，但是在单击时看不到它被调用。当我从主列表中单击该设备时，我会看到API返回的详细信息，具体取决于我单击的是哪个设备，这样才能正常工作，但我无法获取它来显示结果：

D/MainActivity2: LOOK HERE!!! DeviceDetails(attributes=[Attribute(currentValue=present, dataType=ENUM, name=presence, values=[present, not present])], capabilities=null, commands=[arrived, departed], id=98, name=Presence - Matt)

MainActivity2

class MainActivity2 : AppCompatActivity() {
    private val tag : String = MainActivity2::class.java.simpleName
    private lateinit var adapterDetails: DeviceDetailsAdapter

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main2)
        rv_devices_details.layoutManager = LinearLayoutManager(this)
        rv_devices_details.hasFixedSize()
        adapterDetails = DeviceDetailsAdapter(listOf()) {deviceDetails -> deviceClicked(deviceDetails) }
        rv_devices_details.adapter = adapterDetails
        loadDeviceDetails()
    }

        private fun loadDeviceDetails() {
            GlobalScope.launch(Dispatchers.Main) {
                try {
                    var deviceID: String = intent.getStringExtra("deviceID")
                    val webResponseDetails = DeviceDetailsWebAccess.deviceDetailsApi.getDevicesDetailsAsync(deviceID = deviceID, access_token = "5dbbeea3-91bd-4dbc-983b-af8e2c18e18f").await()
                    if (webResponseDetails.isSuccessful) {

                        Log.d(tag, "LOOK HERE!!! $deviceDetails")
                        adapterDetails.notifyDataSetChanged()
                    } else {
                        Log.e(tag, "Error ${webResponseDetails.code()}")
                        Toast.makeText(this@MainActivity2, "Error ${webResponseDetails.code()}", Toast.LENGTH_LONG).show()
                    }
                } catch (e: IOException) {
                    Log.e(tag, "Exception " + e.printStackTrace())
                    Toast.makeText(this@MainActivity2, "Exception ${e.message}", Toast.LENGTH_LONG).show()
                }
            }
        }
    private fun deviceClicked(deviceDetails: DeviceDetails) {
        Toast.makeText(this, "Clicked: ${deviceDetails.name}", Toast.LENGTH_LONG).show()
        val showDetailActivityIntent = Intent(this, MainActivity2::class.java)
        showDetailActivityIntent.putExtra("deviceID", deviceDetails.id)
        startActivity(showDetailActivityIntent)
    }
    }

DeviceDetailsAdapter

class DeviceDetailsAdapter (private var deviceDetails: List<DeviceDetails>, private val clickDetailsListener: (DeviceDetails) -> Unit) :
    RecyclerView.Adapter<RecyclerView.ViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
        val inflater = LayoutInflater.from(parent.context)
        val viewDetails = inflater.inflate(R.layout.device_detail, parent, false)
        return DeviceDetailHolder(viewDetails)
    }

    override fun onBindViewHolder(holderDetails: RecyclerView.ViewHolder, position: Int) {
        (holderDetails as DeviceDetailHolder).bindDetails(deviceDetails[position], clickDetailsListener)
    }

    override fun getItemCount() = deviceDetails.size

    class DeviceDetailHolder(devicedetailView: View) : RecyclerView.ViewHolder(devicedetailView) {
        fun bindDetails(deviceDetails: DeviceDetails, clickDetailsListener: (DeviceDetails) -> Unit) {
            itemView.device_detail_name.text = deviceDetails.name
            Logger.getLogger(DeviceDetailsAdapter::class.java.name).warning("LOOK HERE NOW!!! $deviceDetails.name")
            itemView.device_detail_id.text = deviceDetails.id
            Logger.getLogger(DeviceDetailsAdapter::class.java.name).warning("LOOK HERE NOW!!! $deviceDetails.id")
        }

    }
}

</android.support.constraint.ConstraintLayout>

我感觉细节部分试图以某种方式将结果发布到第一个视图，或者不是以某种方式从API调用中获取数据。

第二次API调用未显示详细信息
