알람 RecyclerView
이전에 만들어 놓은 alarmDTO를 이용하여 데이터베이스에서 알람 내용을 읽어와 알람 화면에 띄워보자.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<androidx.recyclerview.widget.RecyclerView
android:id="@+id/alarmFragment_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>alarm fragment이다.
알람을 recyclerview에 하나씩 올려보자.

FirebaseFirestore.getInstance().collection("profileImages").document(alarmDTOList[position].uid!!).get().addOnCompleteListener { task ->
if(task.isSuccessful){
val url = task.result!!["image"]
Glide.with(view.context).load(url).apply(RequestOptions().circleCrop()).into(commentViewItemImageProfile)
}

when(alarmDTOList[position].kind){
0 -> {
val str_0 = alarmDTOList[position].userId + getString(R.string.alarm_favorite)
commentViewItemTextProfile.text = str_0
}
1 -> {
val str_1 = alarmDTOList[position].userId + getString(R.string.alarm_comment)
commentViewItemTextProfile.text = str_1
}
2 -> {
val str_2 = alarmDTOList[position].userId + " " + getString(R.string.alarm_follow)
commentViewItemTextProfile.text = str_2
}
}
commentViewItemTextcomment.visibility = View.INVISIBLE
}
override fun getItemCount(): Int {
return alarmDTOList.size

}
}
kind를 이용하여 화면에 띄울 메시지를 결정한다.
또한 Glide를 이용하여 알람을 보낸 사람의 프로필 이미지를 렌더한다.
