Android ArrayListof kotlin Studio 微调器问题

Question

//型号

Class DeviceBT
class DeviceBT(
    private val id: Long,
    private val name: String,
    private val macAddress: String
)

//主要活动：

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

//Spinner Test
    var listDeviceBT = arrayListOf<DeviceBT>()
    listDeviceBT.add(BTDeviceModel(1,"Peripherique 1", "00:00:00:00:01" ))
    listDeviceBT.add(BTDeviceModel(2,"Peripherique 2", "00:00:00:00:02" ))
    listDeviceBT.add(BTDeviceModel(3,"Peripherique 3", "00:00:00:00:03" ))
    listDeviceBT.add(BTDeviceModel(4,"Peripherique 4", "00:00:00:00:04" ))

//spinner adapter
    val spinnerBTAdapter = ArrayAdapter<DeviceBTDataLight>(this, R.layout.support_simple_spinner_dropdown_item,listDeviceBTLight)
    spinnerBTAdapter.setDropDownViewResource(R.layout.support_simple_spinner_dropdown_item)
    spinner_BTAssocied.adapter = spinnerBTAdapter
}

微调列表没有return文本，returnAdapter.BTDeviceModel@456654e 如何获取名称的值？感谢您的帮助

Answer 1

重写 DeviceBT 中的 toString 方法 class。

override fun toString(): String {
        return name
    }
