以下代码:

FirestoreRecyclerOptions options = new FirestoreRecyclerOptions.Builder<Inventory>().setQuery(query, Inventory.class).build();

Inside setQuery(),it shows Cannot resolve symbol 'QueryListenOptions'

如何解决以上问题？

Answer 1

Firebase Release Notes解释了这一变化:

Replaced the DocumentListenOptions and QueryListenOptions classes with a MetadataChanges enum. Instead of calling addSnapshotListener() with either of those classes, use the enum:

addSnapshotListener(MetadataChanges.INCLUDE, ...)

截至 5 月 3 日，Firestore 文档尚未更新以包含 MetadataChanges。作为引用，这是反编译的类文件:

package com.google.firebase.firestore;

public enum MetadataChanges {
    EXCLUDE,
    INCLUDE;

    private MetadataChanges() {
    }
}

更新 FirebaseUI version 3.3.1使用 Firebase SDK 版本 15.0.0 构建。它与 Firestore 16.0.0 不兼容。由于您使用的是 FirebaseUI 3.3.1，因此必须使用 Firestore 15.0.0 进行构建。
