Question

运行RecyclerView UI时出现错误

 @Override
public void onStart() {
    super.onStart();
final FirebaseRecyclerAdapter<request_recycle, requestViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<request_recycle, requestViewHolder>(request_recycle.class, R.layout.request_trip_layout, requestViewHolder.class, query_car) {
        @Override
        protected void populateViewHolder(final requestViewHolder viewHolder, final request_recycle model, int position) {
};

}

我收到此错误：

java.lang.RuntimeException: java.lang.NoSuchMethodException: <init> [class android.view.View]
    at com.firebase.ui.a.b.a(Unknown Source)
    at android.support.v7.widget.RecyclerView$a.b(Unknown Source)
    at android.support.v7.widget.RecyclerView$p.a(Unknown Source)
    at android.support.v7.widget.RecyclerView$p.a(Unknown Source)

依赖项是：

 implementation 'com.google.firebase:firebase-core:16.0.1'
 implementation 'com.google.firebase:firebase-database:16.0.1' 
 implementation 'com.google.firebase:firebase-auth:16.0.1' 
 implementation 'com.google.firebase:firebase-storage:16.0.1' 
 implementation 'com.google.firebase:firebase-messaging:17.0.0' 
 implementation 'com.firebaseui:firebase-ui-database:0.4.0' 
 implementation 'com.firebaseui:firebase-ui-auth:3.1.0'

将两个firebaseUI依赖项更新为以下内容：

implementation 'com.firebaseui:firebase-ui-database:4.1.0'
implementation 'com.firebaseui:firebase-ui-auth:4.1.0'

因此它们与您正在使用的Firebase库兼容，因为这可能会引起问题。

然后使用以下代码：

 FirebaseRecyclerOptions<request_recycle> options =
            new FirebaseRecyclerOptions.Builder<Chat>()
                    .setQuery(query_car, request_recycle.class)
                    .build();

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<request_recycle, requestViewHolder>(options) {
@Override
public ChatHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // Create a new instance of the ViewHolder, in this case we are using a custom
    // layout called R.layout.message for each item
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.request_trip_layout, parent, false);

    return new ChatHolder(view);
}

@Override
protected void onBindViewHolder(ChatHolder holder, int position, Chat model) {
    // Bind the Chat object to the ChatHolder
    // ...
    }
 };

不要忘记阅读docs，并进行以下检查：

https://github.com/firebase/FirebaseUI-Android/blob/version-4.1.0/database/README.md#firebaserecycleradapter-lifecycle

您需要使用adapter.startListening();，以便数据可以显示在recyclerview中。
