Мне нужен доступ к строкам в strings.xml из пользовательского класса Recycler Adapter, но я получаю сообщение об ошибке, как описано. Вот мой класс Kotlin Recycler Adapter с методом onBindViewHolder(), где я пытаюсь получить доступ к строкам с заполнителями miles и poundSign:
import android.content.res.Resources
import android.provider.Settings.Global.getString
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TextView
import androidx.recyclerview.widget.RecyclerView
import java.text.DecimalFormat
class SiteAdapter(
private val mainActivity: CountiesActivity,
private val siteList: List<Site>) : RecyclerView.Adapter<SiteAdapter.ListItemHolder>() {
inner class ListItemHolder(view: View):
RecyclerView.ViewHolder(view),
View.OnClickListener {
internal var name = view.findViewById<View>(R.id.textViewSiteName) as TextView
internal var distance = view.findViewById<View>(R.id.textViewSiteDistance) as TextView
internal var price = view.findViewById<View>(R.id.textViewSitePrice) as TextView
init {
view.isClickable = true
view.setOnClickListener(this)
}
override fun onClick(view: View) {
mainActivity.showDetails(adapterPosition)
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ListItemHolder {
val itemView = LayoutInflater.from(parent.context)
.inflate(R.layout.recycler_list_item, parent, false)
return ListItemHolder(itemView)
}
override fun getItemCount(): Int {
if (siteList != null) {
return siteList.size
}
// error
return -1
}
override fun onBindViewHolder(holder: ListItemHolder, position: Int) {
val site = siteList[position]
holder.name.text = site.name
holder.distance.text = site.distance.toString() + Resources.getSystem().getString(R.string.miles)
val decimalFormatter = DecimalFormat("#,###.00")
holder.price.text = Resources.getSystem().getString(R.string.poundSign) + decimalFormatter.format(site.price).toString()
}
}
Вот мой файл strings.xml:
<resources>
<string name="app_name">GoSiteUK</string>
<string name="title_england">England</string>
<string name="title_scotland">Scotland</string>
<string name="title_wales">Wales</string>
<string name="title_nireland">N.Ireland</string>
<string name="helpInstructions">\n\n\n\n\n\nSelect from the available countries at the bottom of the screen to display a list of
counties for that country. Then select a county for which you wish to see campsites, caravan sites or motorhome sites. Select
a particular site that you wish to travel to and you will be presented with more information about the site. Click on \"Take Me
Here\" and a map will be displayed with navigation instructions and route information to follow to take you to that selected
site.\n\nFor support contact:\n\nriverstonetechuk@gmail.com\n</string>
