我正在开发我的应用程序,我需要列出一小组这样的小视图:
(我无法发布图片,因为StackOverflow是我不出名的原因)
该片段已显示,并且已正确应用,但我尝试显示的视图组未显示。
我找不到如何使片段清晰可见并使按钮正常工作的方法(但这不是重点,因此稍后再问)
class EditFragment : Fragment() {
lateinit var option : Spinner
lateinit var result : TextView
private lateinit var viewOfLayout: View
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
viewOfLayout = inflater.inflate(R.layout.edit_fragment, container, false)
val mainLayout = viewOfLayout.findViewById(R.id.scrollView1) as ScrollView
//create a view to inflate the layout_item (the xml with the textView created before)
val view = layoutInflater.inflate(R.layout.sensor_item, mainLayout, false)
val options = arrayOf("A","V")
option = view.spinner as Spinner
result = view.textView7 as TextView
option.adapter = ArrayAdapter<String>(activity,android.R.layout.simple_list_item_1,options)
return viewOfLayout
}
}
这是完整的代码:https://pastebin.com/fYyXkupM
(我想我的片段可以正确显示)
->我认为我的错误是从那里来的:
val view = layoutInflater.inflate(R.layout.sensor_item, mainLayout, false)
如果我将“ mainLayout”替换为“ container”,则可以正常工作,但不是该片段的子级。
谢谢。
答案 0 :(得分:0)
You haven't initialized option Spinner from viewOfLayout.
答案 1 :(得分:0)
好的,即使这有点具体,我也找到了答案:
val view = layoutInflater.inflate(R.layout.sensor_item, container, false)
val insertPoint = viewOfLayout.findViewById(R.id.box_Parent) as LinearLayout
insertPoint.addView(view2, 0)
