如何结合Recyclerview和Fragment？

Question

I would like to combine a Recyclerview in an Activity that uses a TabLayout(Fragment), so that I can swipe between the different lists. However so far I only achieve to do either a ListActivity OR the tabbed activity (the standard one from android studio) but not both. Would be glad if someone could help on this.

AdapterFish.java

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.Collections;
import java.util.List;

public class AdapterFish extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private Context context;
    private LayoutInflater inflater;
    List<DataFish> data= Collections.emptyList();
    DataFish current;
    int currentPos=0;

    // create constructor to innitilize context and data sent from MainActivity
    public AdapterFish(Context context, List<DataFish> data){
        this.context=context;
        inflater= LayoutInflater.from(context);
        this.data=data;
    }

    // Inflate the layout when viewholder created

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view=inflater.inflate(R.layout.tab2, parent,false);
        MyHolder holder=new MyHolder(view);
        return holder;
    }

    // Bind data
    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

        // Get current position of item in recyclerview to bind data and assign values from list
        MyHolder myHolder= (MyHolder) holder;
        DataFish current=data.get(position);
        myHolder.textmatkul.setText(current.matkul);
        myHolder.textwaktu_batal.setText("Tanggal Batal: " + current.waktu_batal);
        myHolder.textwaktu_pengganti.setText("Tanggal Pengganti: " + current.waktu_pengganti);
        myHolder.textdosen.setText("Nama Dosen: " + current.dosen);
        myHolder.textruang.setText("Ruang: " + current.ruang);
        myHolder.textalasan.setText("Alasan: " + current.alasan);
    }

    // return total item from List
    @Override
    public int getItemCount() {
        return data.size();
    }

    class MyHolder extends RecyclerView.ViewHolder{

        TextView textmatkul;
        TextView textwaktu_batal;
        TextView textwaktu_pengganti;
        TextView textdosen;
        TextView textruang;
        TextView textalasan;

        // create constructor to get widget reference
        public MyHolder(View itemView) {
            super(itemView);
            textmatkul= (TextView) itemView.findViewById(R.id.textmatkul);
            textwaktu_batal = (TextView) itemView.findViewById(R.id.textwaktu_batal);
            textwaktu_pengganti = (TextView) itemView.findViewById(R.id.textwaktu_pengganti);
            textdosen = (TextView) itemView.findViewById(R.id.textdosen);
            textalasan = (TextView) itemView.findViewById(R.id.textalasan);
            textruang = (TextView) itemView.findViewById(R.id.textruang);
        }

    }
}

Tab2.java :

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

/**

public class Tab2 extends Fragment {
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.tab2, container, false);
    }
}

Try to follow below steps:

1. Design your activity_main.xml with Toolbar , TabLayout and ViewPager
2. Design layout XML's with RecyclerView for your fragments that you want to show for each Tab content.
3. Use FragmentPagerAdapter to populate Fragments on ViewPager
4. Set FragmentPagerAdapter to ViewPager using ViewPager.setAdapter(FragmentPagerAdapter)
5. Use TabLayout.setupWithViewPager(ViewPager) to give ability to ViewPager to work with TabLayout functionalities.
6. For individual Fragment , create RecyclerViewAdapter to populate data to RecyclerView

Here is a simple tutorial . Hope this will help~
