如何在 RecyclerView.Adapter 中获取 LifecycleOwner 引用？

Question

目前，我用mLifecycleOwner = mContext as LifecycleOwnerget LifecycleOwner，它可以工作，但我认为它不是一个好的代码。

我怎样才能LifecycleOwner从ListAdapter？

class VoiceAdapters (private val aHomeViewModel: HomeViewModel, private val mPlay: PlayInterface):
        ListAdapter<MVoice, VoiceAdapters.VoiceViewHolder>(MVoiceDiffCallback()) {

    private lateinit var mContext: Context
    private lateinit var mLifecycleOwner:LifecycleOwner

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VoiceViewHolder {
        mContext = parent.context
        mLifecycleOwner = mContext as LifecycleOwner

        return VoiceViewHolder(
            LayoutVoiceItemBinding.inflate(LayoutInflater.from(parent.context), parent, false).also {               
               it.lifecycleOwner = mLifecycleOwner
               it.aHomeViewModel = aHomeViewModel
            }
        )
    }

    ...
}

Answer 1

1. 将其作为构造函数参数传递给 VoiceAdapters
2. 创建扩展属性：

   val View.lifecycleOwner get() = ViewTreeLifecycleOwner.get(this)`

然后访问它： parent.lifecycleOwner

3. 只解决一次：

 override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VoiceViewHolder {
       if(!::lifecycleOwner.isInitialized){
        lifecycleOwner = parent.context as LifecycleOwner
      }
}

它们指向相同LifecycleOwner的Context， 用于膨胀布局。

ViewTreeLifecycleOwner.get(view)是获取视图底层的便捷方式LifecycleOwner。因此，我的两分钱去选项 1 或 2。
