我想在我的项目中使用FirebaseRecyclerAdapter,并且在以前的项目中使用了此代码段,它工作正常,但现在不再起作用,新版本的FirebaseUi是否有无法更新的更新?现在允许我重用此代码吗?

我在项目中尝试过

@Override
    protected  void onStart(){
        super.onStart();
        FirebaseRecyclerAdapter<Model,ViewHolder> firebaseRecyclerAdapter =
                new FirebaseRecyclerAdapter<Model, ViewHolder>(
                        Model.class,
                        R.layout.row,
                        ViewHolder.class,
                        mRef

                ) {
                    @Override
                    protected void onBindViewHolder( ViewHolder holder, int position,  Model model) {
                        holder.setDetails(getApplicationContext(),model.getTitel(),model.getImages(),model.getDesc());
                    }

                };
        mRecyclerView.setAdapter(firebaseRecyclerAdapter);
    }

并且Android Studio出现错误,提示您必须实现onCreateViewHolder,onBindViewHolder方法。

ViewHolder类

package com.example.varunwadhwa.myapplication;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.TextView;

import com.squareup.picasso.Picasso;
import com.squareup.picasso.Target;

public class ViewHolder extends RecyclerView.ViewHolder {

    View mView;

    public ViewHolder(View itemView) {
        super(itemView);

        mView = itemView;
    }
    public void setDetails(Context ctx,String title, String desc , String image ){
        TextView mTitleView = mView.findViewById(R.id.rTitleTv);
        TextView mDtailTv = mView.findViewById(R.id.rDescTv);
        TextView mImageTv = mView.findViewById(R.id.rImageView);
        mTitleView.setText(title);
        mDtailTv.setText(desc);
        Picasso.get().load(image).into((Target) mImageTv);
    }
}

我使用此依赖项


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-database:16.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.firebaseui:firebase-ui-database:4.0.1'
    implementation 'com.squareup.picasso:picasso:2.71828'
}
