RecyclerView的使用 以及RecyclerView的自定义点击事件

首先Xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.longfei.recyclerviewdemo.MainActivity">

    <android.support.v7.widget.RecyclerView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/RecyclerView"
        />
</LinearLayout>

MainActivity主代码

package com.example.longfei.recyclerviewdemo;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.GridLayoutManager;
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 RecyclerView1;
    private List<Bean> data = new ArrayList<Bean>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        //首先添加数据
        for (int i = 0; i < 10; i++) {
            Bean b = new Bean(R.mipmap.a2,"我是姓名"+i,"我是年龄"+i);
            data.add(b);
        }
        System.out.println(data.size());
        initView();
    }

    private void initView() {


        //找控件
        RecyclerView1 = (RecyclerView) findViewById(R.id.RecyclerView);
        //选择是线性还是网格

        //RecyclerView1.setLayoutManager(new LinearLayoutManager(this));
        RecyclerView1.setLayoutManager(new GridLayoutManager(this,3));
        //适配器
        MyAdapter myAdapter = new MyAdapter(this, data);
        RecyclerView1.setAdapter(myAdapter);

        //RecyclerView的点击事件
        RecyclerView1.addOnItemTouchListener(new RecyclerItemClickListener(MainActivity.this, RecyclerView1, new RecyclerItemClickListener.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                Toast.makeText(MainActivity.this,"我是点击事件",Toast.LENGTH_LONG).show();
            }
            @Override
            public void onItemLongClick(View view, int position) {
                Intent intent = new Intent(MainActivity.this,Main2Activity.class);
                startActivity(intent);
            }
        }));
    }

}


MyAdapter适配器

package com.example.longfei.recyclerviewdemo;

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;

import java.util.List;

/**

 */
class MyAdapter extends RecyclerView.Adapter {

    //传来的值
    private MainActivity mMainActivity;
    private List<Bean> data;

    //有参构造
    public MyAdapter(MainActivity mainActivity, List<Bean> data) {
        mMainActivity = mainActivity;
        this.data = data;
    }
    //自定义一个ViewHodler 在这里面找控件
    class ViewHodler extends RecyclerView.ViewHolder {

        private ImageView mImageView;
        private TextView mName;
        private TextView mAge;
        public ViewHodler(View itemView) {
            super(itemView);
            mImageView = (ImageView) itemView.findViewById(R.id.image);
            mName = (TextView) itemView.findViewById(R.id.name);
            mAge = (TextView) itemView.findViewById(R.id.age);
        }
    }

    //让布局与我们的ViewHolder绑定在一起
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new ViewHodler(LayoutInflater.from(mMainActivity).inflate(R.layout.item,null));
    }

    //更新数据
    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        //首先得到holdler

        ViewHodler h = (ViewHodler) holder;
        Bean bean = data.get(position);
        h.mName.setText(bean.getName());
        h.mAge.setText(bean.getAge());

        h.mImageView.setImageResource(bean.getImages());

//
//            h.mImageView.setOnClickListener(new View.OnClickListener() {
//                @Override
//                public void onClick(View view) {
//                    Toast.makeText(mMainActivity,"的三大大厦大厦的",Toast.LENGTH_LONG).show();
//                }
//            });
    }

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

}



自定义点击事件
package com.example.longfei.recyclerviewdemo;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
    public interface OnItemClickListener {
        void onItemClick(View view, int position);

        void onItemLongClick(View view, int position);
    }

    private OnItemClickListener mListener;

    private GestureDetector mGestureDetector;

    public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
        mListener = listener;

        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View childView = recyclerView.findChildViewUnder(e.getX(), e.getY());

                if (childView != null && mListener != null) {
                    mListener.onItemLongClick(childView, recyclerView.getChildAdapterPosition(childView));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());

        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
    }
}

Bean包

package com.example.longfei.recyclerviewdemo;

/**
 * Created by longfei on 2016/10/11.
 */

public class Bean {



    private int images;
    private String name;

    private String age;

    public int getImages() {
        return images;
    }

    public void setImages(int images) {
        this.images = images;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public Bean(int a2, String s) {
    }

    public Bean(int images, String name, String age) {
        this.images = images;
        this.name = name;
        this.age = age;
    }
}
