我正在尝试最后一个查看日,通过单击recyclerview项目来打开片段.我仍然得到相同的错误:方法getSupportFragmentManager()未定义类型SightsAdapter.ListItemViewHolder

我读了很多线程,但他们无法帮助我,我对android很新.有谁知道我做错了什么？

这是我的代码:

package com.example.stadtfuehrer;



import java.util.ArrayList;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;
import android.view.LayoutInflater;
import android.support.v4.app.*;



public class SightsAdapter  extends RecyclerView.Adapter<SightsAdapter.ListItemViewHolder> {

private ArrayList<Sights> listData;

public SightsAdapter(ArrayList<Sights> list){
    this.listData = list;
}

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

@Override
public void onBindViewHolder(ListItemViewHolder holder, int position){
    Sights sight = listData.get(position);
    holder.textViewSightsName.setText(sight.getName());

}

@Override
public ListItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_listitem_recyclerview, parent, false);
    //itemView.setPadding(10, 5, 10, 5);
    return new ListItemViewHolder(itemView);
} …
