Question

我正在使用Firebase for Android制作博客应用。但是我在应用程序启动时遇到错误。我的代码完全正确，但我仍然收到此错误。

这是catlog错误

这是我的模特Blog.java

public class Blog {

private String title;
private String desc;


public Blog(){

}

public Blog(String title, String desc) {
    this.title = title;
    this.desc = desc;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getDesc() {
    return desc;
}

public void setDesc(String desc) {
    this.desc = desc;
}

}

这是我的MainActivity.java

public class MainActivity extends AppCompatActivity {
private RecyclerView recycleView;
private DatabaseReference fDatabase;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    fDatabase = FirebaseDatabase.getInstance().getReference().child("Blog");

    recycleView = (RecyclerView) findViewById(R.id.recyleView);
    recycleView.setHasFixedSize(true);
    recycleView.setLayoutManager(new LinearLayoutManager(this));
}

@Override
protected void onStart() {
    super.onStart();

    FirebaseRecyclerAdapter<Blog, BlogViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Blog, BlogViewHolder>(
            Blog.class,
            R.layout.post_list_layout,
            BlogViewHolder.class,
            fDatabase
    ) {
        @Override
        protected void populateViewHolder(BlogViewHolder viewHolder, Blog model, int position) {

            viewHolder.setTitle(model.getTitle());
            viewHolder.setDesc(model.getDesc());

        }
    };

    recycleView.setAdapter(firebaseRecyclerAdapter);
}

public static class BlogViewHolder extends RecyclerView.ViewHolder {

    View mView;
    public BlogViewHolder(View itemView){
        super(itemView);

        mView = itemView;
    }

    public void setTitle(String title){
        TextView post_title = (TextView) mView.findViewById(R.id.txtBlogTitle);

        post_title.setText(title);

    }

    public void setDesc(String desc){
        TextView post_desc = (TextView) mView.findViewById(R.id.txtBlogDesc);

        post_desc.setText(desc);
    }

}

}

提前致谢...

请在firebase文件下的Google-play-services中将所有dependencies和app.gradle库版本更改为相同版本。

使用FirebaseRecyclerView时出错，在Lcom / google / android / gms / internal / zzaac类中没有静态方法zza（Landroid / app / Application;）V;
