如何解决自定义对话框未与某些 XML 一起显示
我正在尝试显示自定义对话框,但它没有显示,而是使背景透明。最奇怪的是,当我只更改自定义对话框 xml 时,它显示没有问题,所以我认为它可能是 xml,但我一直在寻找一段时间,但我找不到问题。
这是片段代码:
class DeleteConfirmationFragment : Fragment() {
private lateinit var binding: FragmentDeleteConfirmationBinding
lateinit var dialog : Dialog
override fun onCreateView(
inflater: LayoutInflater,container: ViewGroup?,savedInstanceState: Bundle?
): View? {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_delete_confirmation,container,false)
}
override fun onViewCreated(view: View,savedInstanceState: Bundle?) {
super.onViewCreated(view,savedInstanceState)
binding = FragmentDeleteConfirmationBinding.bind(view)
dialog = context?.let { Dialog(it) }!!
binding.btnNo.setonClickListener {
openDeletedAccountDialog()
}
}
private fun openDeletedAccountDialog() {
dialog.setContentView(R.layout.dialog_deleted_account) // if i change this xml file for other it
//works properly so i think it Could be an android bug..
dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
dialog.show()
}
}
这是不起作用的xml:

如果我像这样在打开的已删除对话框功能中只更改 xml,它会正确显示另一个对话框:
private fun openDeletedAccountDialog() {
dialog.setContentView(R.layout.dialog_friendzone_layout) // <-- change made here
dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
dialog.show()
}
知道发生了什么吗?
解决方法
我也遇到了同样的问题,这是因为我在 0dp
中使用了 ConstrintLayout
以使用 match_constraint
大小,但它在对话框中不起作用。
您只需将 android:layout_width="0dp"
的 CardView
更改为 android:layout_width="match_parent"
。
