java - Gradle 构建错误地失败，因为 "@Override method does not override method from superclass"

Question

代码如下。 IDE 的代码没问题，但 gradle 拒绝构建，并表示:

TextAdapter is not abstract and does not override abstract method onBindViewHolder(TextAdapter.SimpleTextHolder,int) in Adapter public class TextAdapter extends RecyclerView.Adapter {

error: method does not override or implement a method from a supertype

我知道这是错误的，因为我使用 Android Studio 生成了该方法，所以我认为这一定是一个 gradle 错误？

RecyclerView适配器代码:

import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import ...R;
import ...jsonObjects.Nameable;

import java.util.ArrayList;

public class TextAdapter<T extends Nameable> extends RecyclerView.Adapter<TextAdapter.SimpleTextHolder> {

    private ArrayList<T> items;
    private ClickListener<T> clickListener;

    public TextAdapter(ArrayList<T> items, ClickListener<T> onClick) {
        this.items = items;
        this.clickListener = onClick;
    }

    @Override
    public SimpleTextHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.holder_text, parent, false);
        return new SimpleTextHolder(view);
    }

    @Override
    public void onBindViewHolder(SimpleTextHolder holder, int position) {
        holder.itemTitle.setText(items.get(position).getName());
    }


    @Override
    public int getItemCount() {
        return items.size();
    }

    class SimpleTextHolder extends RecyclerView.ViewHolder {

        TextView itemTitle;

        SimpleTextHolder(View itemView) {
            super(itemView);

            itemTitle = itemView.findViewById(R.id.itemTitle);
            itemView.setOnClickListener(v -> clickListener.onClick(items.get(getAdapterPosition())));
        }

    }

    public interface ClickListener<T> {

        void onClick(T item);

    }

}

Answer 1

您可以通过将您的 SimpleTextHolder 类设为 static 来解决此问题，即

static class SimpleTextHolder extends RecyclerView.ViewHolder {
    // ...
}
