单击下拉菜单时,微调器没有打开。有帮助吗? 我的项目列表在字符串资源中。
class CreateIssueFragment : Fragment() {
var spinner: Spinner? = null
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
val rootView: View = inflater.inflate(R.layout.fragment_create_issue, container, false)
spinner = activity?.issueTypesSpinner
loadSpinner()
return rootView
}
private fun loadSpinner() {
ArrayAdapter.createFromResource(context, R.array.issue_types_array, android.R.layout.simple_spinner_item)
.also { adapter ->
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
spinner?.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
override fun onItemSelected(parent: AdapterView<*>, view: View, position: Int, id: Long) {
parent.getItemAtPosition(position).toString()
}
override fun onNothingSelected(parent: AdapterView<*>) {
}
}
spinner?.adapter = adapter
}
}
}

尝试这样替换:
yourSpinner?.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
override fun onNothingSelected(parent: AdapterView<*>?) {
}
override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
}
}
