MainActivity.java

package androidwarriors.recycleviewdemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView= (RecyclerView) findViewById(R.id.my_recycler_view);

        RecyclerAdapter adapter=new RecyclerAdapter(this);
        recyclerView.setAdapter(adapter);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
    }
}

RecyclerAdapter.java

package androidwarriors.recycleviewdemo;

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.Toast;


public class RecyclerAdapter extends  RecyclerView.Adapter<RecyclerViewHolder> {

    String [] name={"Androidwarriors","Stackoverflow","Developer Android","AndroidHive",
            "Slidenerd","TheNewBoston","Truiton","HmkCode","JavaTpoint","Javapeper"};
Context context;
    LayoutInflater inflater;
    public RecyclerAdapter(Context context) {
        this.context=context;
        inflater=LayoutInflater.from(context);
    }
    @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v=inflater.inflate(R.layout.item_list, parent, false);

        RecyclerViewHolder viewHolder=new RecyclerViewHolder(v);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(RecyclerViewHolder holder, int position) {

        holder.tv1.setText(name[position]);
        holder.imageView.setOnClickListener(clickListener);
        holder.imageView.setTag(holder);
    }

    View.OnClickListener clickListener=new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            RecyclerViewHolder vholder = (RecyclerViewHolder) v.getTag();
            int position = vholder.getPosition();

            Toast.makeText(context,"This is position "+position,Toast.LENGTH_LONG ).show();

        }
    };



    @Override
    public int getItemCount() {
        return name.length;
    }
}

RecyclerViewHolder.java

package androidwarriors.recycleviewdemo;

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

public class RecyclerViewHolder extends RecyclerView.ViewHolder {

    TextView tv1,tv2;
    ImageView imageView;

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

        tv1= (TextView) itemView.findViewById(R.id.list_title);
        tv2= (TextView) itemView.findViewById(R.id.list_desc);
        imageView= (ImageView) itemView.findViewById(R.id.list_avatar);

    }
}

Answer 1

在Adapter类中，为Recycler View项添加以下代码：

@Override  
    public void onBindViewHolder(final ViewHolder holder, int position) { 
         // holder.itemView is your RelativeLayout which is inside your cardview
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override 
            public void onClick(View v) {
               //do your further respective fragment activity task
            } 
        }); 
    }

Answer 2

@Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {

    holder.tv1.setText(name[position]);
    holder.imageView.setOnClickListener(clickListener);
    holder.imageView.setTag(holder);
}

holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //do your further respective fragment activity task
        switch(position)
        {
            case 0:
                Intent intent=new Intent(your RecyclerActivity Reference, OneFragment.class);
                (Your Activity Reference).startActivity(intent);
        }
    });
