有人知道我需要在RecyclerView适配器中为单击侦听器使用哪个上下文(如果有的话),而不必创建新的DialogFragment类?以后,我将需要访问和使用对话框的视图。 以前使用的代码是我过去在RecyclerView适配器上使用的代码,但是现在在需要使用自定义视图时是多余的。
未解决的参考:“ layoutInflater”
以前使用的代码
holder.myButton.setOnClickListener {
val builder = android.app.AlertDialog.Builder(holder.itemView.context)
builder.setIconAttribute(R.attr.ivInfo)
builder.setTitle(R.string.dialog_title)
builder.setMessage(R.string.dialog_message)
builder.setView(R.layout.custom_view)
builder.setPositiveButton(android.R.string.ok){ dialog, _ -> dialog.dismiss() }
val dialog: android.app.AlertDialog = builder.create()
dialog.show()
}
当前代码
class MyRVAdapter() : RecyclerView.Adapter<MyRVAdapter.ViewHolder>() {
override fun getItemCount(): Int {
return myList.size
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.myButton.setOnClickListener {
customView = holder.itemView.context.this.layoutInflater.inflate(R.layout.fragment_dialog, null)
val builder = AlertDialog.Builder(holder.itemView.context)
builder.setIconAttribute(R.attr.imgNight)
builder.setTitle(R.string.dialog_title)
builder.setView(customView)
builder.setPositiveButton(android.R.string.ok){ dialog, _ -> dialog.dismiss() }
builder.show()
tabLayout = customView.findViewById(R.id.mTabLayout)
viewPager = customView.findViewById(R.id.mViewPager)
val adapter = TabbedDialogAdapter(childFragmentManager)
adapter.addFragment("Tab A", TabbedDialogFragment.createInstance("Description A"))
adapter.addFragment("Tab B", TabbedDialogFragment.createInstance("Description B"))
adapter.addFragment("Tab C", TabbedDialogFragment.createInstance("Description C"))
customView.mViewPager.adapter = adapter
customView.mTabLayout.setupWithViewPager(customView.mViewPager)
}
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val v = LayoutInflater.from(parent.context).inflate(R.layout.my_cv, parent, false)
return ViewHolder(v)
}
class ViewHolder (itemView : View):RecyclerView.ViewHolder(itemView) {
val myButton = itemView.findViewById<Button>(R.id.btn_A)!!
}
}
答案 0 :(得分:0)
要解决您的问题,您可以使用View.inflate()
。
更改此行:
customView = holder.itemView.context.this.layoutInflater.inflate(R.layout.fragment_dialog, null)
对此:
customView = View.inflate(holder.itemView.context, R.layout.fragment_dialog, null)
但是您应该改为在创建ViewHolder时设置侦听器。在ViewHolder或onCreateViewHolder()
的构造函数中。
