从列表视图和领域中删除项目

Question

单击删除按钮时，我正在尝试从列表视图(阵列适配器(中删除一个项目，但在从领域数据库中删除该项目后它崩溃了。

@Override
public View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {
realm = Realm.getDefaultInstance();
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.meditations_list_item, parent, false);
}
Reminder reminder = getItem(position);
TextView reminderHour = listItemView.findViewById(R.id.hour_tv);
final ImageView deleteBtn = listItemView.findViewById(R.id.delete_btn);
deleteBtn.setTag(position);
final View finalListItemView = listItemView;
deleteBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final Integer index = (Integer) deleteBtn.getTag();
Reminder deletedReminder = getItem(index);
if (deletedReminder == null) {
Toast.makeText(getContext(), "Error in deleting!", Toast.LENGTH_SHORT).show();
return;
}
String id = deletedReminder.getId();
realm.beginTransaction();
RealmResults<Reminder> reminderObjs = realm.where(Reminder.class)
.equalTo("id", id)
.findAll();
boolean isDeleted = reminderObjs.deleteAllFromRealm();
realm.commitTransaction();
notifyDataSetChanged();
Log.d(TAG, "execute: " + isDeleted);

}
});

reminderHour.setText(reminder.getHours());
return listItemView;
}

我现在正在使用此代码删除它正在工作的项目，但我认为此代码可能会导致性能问题：

clear();
addAll(new ArrayList<Reminder>(realm.where(Reminder.class).findAll()));
notifyDataSetChanged();

我改用了RealmBaseAdapter。
