无法将Firebase中的runTransaction (com.firebase.client.Transaction.Handler)应用于(匿名com.google.firebase.database.Transaction.Handler)

import com.google.firebase.database.DataSnapshot;
import com.google.firebase.database.DatabaseError;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import com.google.firebase.database.MutableData;
import com.google.firebase.database.Transaction;

public class Example {
    public static void main(String[] args) {
        DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference("path/to/data");

        databaseRef.runTransaction(new Transaction.Handler() {
            @Override
            public Transaction.Result doTransaction(MutableData mutableData) {
                // 在这里执行事务的读取和写入操作
                return Transaction.success(mutableData);
            }

            @Override
            public void onComplete(DatabaseError databaseError, boolean committed, DataSnapshot dataSnapshot) {
                // 事务完成后的回调函数
            }
        });
    }
}
