具有数据绑定的约束布局无响应

Question

我面临的问题是约束布局完全没有响应。不显示边距，onCLick 处理程序不工作。下面我附上了 2 张图片。看看这个。我哪里错了？需要更多代码..？我可以更新让我知道。

行布局Class

 <?xml version="1.0" encoding="utf-8"?>
 <layout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<variable
    name="lead"
    type="com.goplannr.model.LeadPojo" />

<variable
    name="eventHandler"
   type="com.goplannr.fragment.contact.adapter.LeadClientRVAdapter" />

 </data>

<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:background="@color/colorControlActivated"
android:onClick="@{(v) -> eventHandler.onRowItemClick(v)}">

.... got 4 items inside

</android.support.constraint.ConstraintLayout>

</layout>

RecyclerViewAdapter

 class LeadClientRVAdapter (private val leadDetailsList:ArrayList<LeadPojo>) :
RecyclerView.Adapter<LeadClientRVAdapter.MyViewHolder>() {

 override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
val inflater = LayoutInflater.from(parent.context)
val binding = RowLeadsClientsBinding.inflate(inflater)
return MyViewHolder(binding)
}

override fun getItemCount(): Int = leadDetailsList.size

override fun onBindViewHolder(holder: MyViewHolder, position: Int) = holder.bind(leadDetailsList[position])

inner class MyViewHolder(private val binding: RowLeadsClientsBinding): RecyclerView.ViewHolder(binding.root){
fun bind(item : LeadPojo){
    binding.lead = item
    binding.executePendingBindings()
}}

fun onRowItemClick(v: View){
v.findNavController().navigate(R.id.action_contacts_fragment_to_lead_details_fragment)
}}

有数据绑定 - 没有 -

另一点 - 我只在 Gradle -> dataBinding { 启用真 }

没有别的

Answer 1

Inflation 代码不正确。使用这个

 val binding = RowLeadsClientsBinding.inflate(inflater, parent, false)
