我试图实施一个ListView，并附上FirebaseListAdapter。我需要显示适配器内的字符串列表，所以我使用String作为通用字段。在火力地堡数据库的结构是这样的：在Kotlin中使用FirebaseListAdapter
我需要显示users节点所提供的密钥（102127 ... 102133 ...等），所以我用这个代码来创建适配器：
val ref = db.getReference(MATCHES_REF).child(match).child(USERS_REF)
val adapter = object : FirebaseListAdapter<String>(this, String::class.java, R.layout.cell_friends, ref) {
override fun populateView(view: View, s: String, i: Int) {
val text = view.findViewById(R.id.text_view) as TextView
text.text = s
}
}
listView?.adapter = adapter
这是Android Studio中所示的错误：
Error:(50, 32) None of the following functions can be called with the arguments supplied: public constructor FirebaseListAdapter(activity: Activity!, parser: ((DataSnapshot!) -> String!)!, @LayoutRes modelLayout: Int, query: Query!) defined in com.firebase.ui.database.FirebaseListAdapter public constructor FirebaseListAdapter(activity: Activity!, parser: SnapshotParser!, @LayoutRes modelLayout: Int, query: Query!) defined in com.firebase.ui.database.FirebaseListAdapter public constructor FirebaseListAdapter(activity: Activity!, modelClass: Class!, @LayoutRes modelLayout: Int, query: Query!) defined in com.firebase.ui.database.FirebaseListAdapter
任何解决方案？
