主要是在介面卡裡面編寫在程式碼裡面呼叫:

核心程式碼:

    private OnItemClickListener onItemClickListener;//點選事件
    private OnItemLongClickListener onItemLongClickListener;//長按事件
    private OnRightItemClickListener onRightItemClickListener;//item裡面控制元件的點選事件

    public interface OnItemClickListener {//點選事件的介面
        void onClick(int position);
    }

    public interface OnItemLongClickListener {//長按事件的介面
        void onItemLongClick(int position);
    }

    public interface OnRightItemClickListener{//item裡面控制元件的介面
        void onRightClick(int position);
    }

    public void setOnItemClickListener(OnItemClickListener onItemClickListener) {//點選事件的方法
        this.onItemClickListener = onItemClickListener;
    }

    public void setOnItemLongClickListener(OnItemLongClickListener onItemLongClickListener) {//長按事件的方法
        this.onItemLongClickListener = onItemLongClickListener;
    }

    public void setOnRightItemClickListener(OnRightItemClickListener onRightItemClickListener){//item裡面控制元件的點選的方法
        this.onRightItemClickListener=onRightItemClickListener;
    }
 

        if (onItemClickListener != null) {
            myHolder.mText.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    onItemClickListener.onClick(i);
                }
            });
        }
        if (onItemLongClickListener != null) {
            myHolder.mText.setOnLongClickListener(new View.OnLongClickListener() {
                @Override
                public boolean onLongClick(View v) {
                    onItemLongClickListener.onItemLongClick( i);
                    //返回true 表示消耗了事件 事件不會繼續傳遞
                    return true;
                }
            });
        }
        if (onRightItemClickListener != null) {
            myHolder.mText2.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    onRightItemClickListener.onRightClick(i);
                }
            });
        }
 

使用:

        myAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {
            @Override
            public void onClick(int position) {
                Toast.makeText(MainActivity.this,"點選了第"+position+"條資料",Toast.LENGTH_SHORT).show();
            }
        });
        myAdapter.setOnItemLongClickListener(new MyAdapter.OnItemLongClickListener() {
            @Override
            public void onItemLongClick( int position) {
                Toast.makeText(MainActivity.this,"長按了第"+position+"條資料",Toast.LENGTH_SHORT).show();

            }
        });
        myAdapter.setOnRightItemClickListener(new MyAdapter.OnRightItemClickListener() {
            @Override
            public void onRightClick(int position) {
                Toast.makeText(MainActivity.this,"點選了第"+position+"條下單",Toast.LENGTH_SHORT).show();

            }
        });
 

下面是完整的介面卡程式碼:

package com.example.administrator.recyclerviewdemo;

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

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    private RecyclerView mCeshiList;
    private MyAdapter myAdapter;
    private List<String> list;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mCeshiList=findViewById(R.id.ceshilist);
        setList();
    }
    public void setList(){
        list=new ArrayList<>();
        for (int i=0;i<50;i++){
            list.add("第"+i+"條資料");
        }
        LinearLayoutManager linearLayoutManager=new LinearLayoutManager(this);
        mCeshiList.setLayoutManager(linearLayoutManager);
        myAdapter=new MyAdapter(this,list);
        myAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {
            @Override
            public void onClick(int position) {
                Toast.makeText(MainActivity.this,"點選了第"+position+"條資料",Toast.LENGTH_SHORT).show();
            }
        });
        myAdapter.setOnItemLongClickListener(new MyAdapter.OnItemLongClickListener() {
            @Override
            public void onItemLongClick( int position) {
                Toast.makeText(MainActivity.this,"長按了第"+position+"條資料",Toast.LENGTH_SHORT).show();

            }
        });
        myAdapter.setOnRightItemClickListener(new MyAdapter.OnRightItemClickListener() {
            @Override
            public void onRightClick(int position) {
                Toast.makeText(MainActivity.this,"點選了第"+position+"條下單",Toast.LENGTH_SHORT).show();

            }
        });
        mCeshiList.setAdapter(myAdapter);
    }
}
