无法解析符号'FirebaseRecyclerOptions'

Question

我正在制作一个回收器视图。当我尝试添加firebase的database-ui时，它似乎不起作用。I got error:

Cannot resolve symbol 'FirebaseRecyclerOptions'

我发现它没有被导入，并手动导入，但出现错误:

Cannot resolve symbol 'firebase'

我寻找解决方案。2022年5月3日更新所有firebase依赖的最新版本。但一切都没有改变。

这是我的依赖项:

dependencies {
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
implementation platform('com.google.firebase:firebase-bom:29.3.1')
implementation 'com.google.firebase:firebase-auth:21.0.3'
implementation 'com.google.firebase:firebase-database:20.0.4'
implementation 'com.google.firebase:firebase-storage:20.0.1'
implementation 'com.google.firebaseui:firebase-ui-database:8.0.1'
implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.4.1'
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.1'
implementation 'androidx.navigation:navigation-fragment:2.4.2'
implementation 'androidx.navigation:navigation-ui:2.4.2' 
implementation 'androidx.recyclerview:recyclerview:1.2.1'
implementation 'androidx.cardview:cardview:1.0.0'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

This is import:

import com.firebase.ui.database.FirebaseRecyclerOptions;

Answer 1

好的。我通过改变依赖项来解决这个问题:

implementation 'com.google.firebaseui:firebase-ui-database:8.0.1'

:

implementation 'com.firebaseui:firebase-ui-database:8.0.1'

com.后无google.。
