如何在DialogFragment中正确使用Android View绑定? [英] How to correctly use Android View Binding in DialogFragment?

问题描述

在DialogFragment()中使用Android视图绑定的正确方法是什么?

What is correct way of using Android View Binding in DialogFragment()?

官方文档仅提及活动和片段: https://developer.android.com/topic/libraries/view-binding

Official documentation mentions only Activity and Fragment: https://developer.android.com/topic/libraries/view-binding

推荐答案

请改用 inflate(LayoutInflater.from(context)).并使用 binding.root 设置构建器视图.

Use inflate(LayoutInflater.from(context)) instead. And use binding.root to set the builder view.

此外，正如Google所建议的那样，最佳做法是在使用片段时，在 onDestroyView()上将 binding 实例设置为null: https://developer.android.com/topic/libraries/view-binding#fragments

Also, as Google suggests, it's best practice to set the binding instance to null at onDestroyView() when using fragments: https://developer.android.com/topic/libraries/view-binding#fragments

示例:

class ExampleDialog : DialogFragment() {

    private var _binding: DialogExampleBinding? = null
    // This property is only valid between onCreateDialog and
    // onDestroyView.
    private val binding get() = _binding!!

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        _binding = DialogExampleBinding.inflate(LayoutInflater.from(context))
        return AlertDialog.Builder(requireActivity())
            .setView(binding.root)
            .create()
    }
    
    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    } 
}
