Android(8)RecyclerView适配器实现多布局item+item内部控件点击事件

&＃64;先看看效果是不是自己想要的吧&＃64;

&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;>item及item内部控件点击事件不懂的可以先点击查看<&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;

使用步骤&＃xff1a;

第一步&＃xff1a;添加RecyclerView适配器依赖

compile &＃39;com.android.support:recyclerview-v7:27.1.1&＃39;

第二步&＃xff1a;布局文件里使用RecyclerView

第三步&＃xff1a;创建两个item子布局填充item内容

itemone.xml

itemtwo.xml

第四步&＃xff1a;定义一个实体类Data&＃xff0c;作为Recyclerview的适配类型

package com.ied.recyclerview.entity;public class Data {public static final int TYPE_ONE &＃61; 1;//类型1public static final int TYPE_TWO &＃61; 2;//类型2public int type;//item内容 类型public int icon;public String username;public String message;public Data(int type, int icon, String username, String message) {this.type &＃61; type;this.icon &＃61; icon;this.username &＃61; username;this.message &＃61; message;}public static int getTypeOne() {return TYPE_ONE;}public static int getTypeTwo() {return TYPE_TWO;}public int getType() {return type;}public void setType(int type) {this.type &＃61; type;}public int getIcon() {return icon;}public void setIcon(int icon) {this.icon &＃61; icon;}public String getUsername() {return username;}public void setUsername(String username) {this.username &＃61; username;}public String getMessage() {return message;}public void setMessage(String message) {this.message &＃61; message;}
}

第五步&＃xff1a;创建自定义MyRecyclerViewAdapter适配器继承RecyclerView.Adapter

package com.ied.recyclerview.adapter;import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.ied.recyclerview.R;
import com.ied.recyclerview.entity.Data;
import java.util.List;public class MyRecyclerViewAdapter extends RecyclerView.Adapter{private List list;//数据源private Context context;//上下文public MyRecyclerViewAdapter(List list, Context context) {this.list &＃61; list;this.context &＃61; context;}&＃64;NonNull&＃64;Overridepublic RecyclerView.ViewHolder onCreateViewHolder(&＃64;NonNull ViewGroup parent, int viewType) {//选择类型switch (viewType){case Data.TYPE_ONE:View view &＃61; LayoutInflater.from(parent.getContext()).inflate(R.layout.item,parent,false);return new OneViewHolder(view);case Data.TYPE_TWO:view &＃61; LayoutInflater.from(parent.getContext()).inflate(R.layout.itemtwo,parent,false);return new TwoViewHolder(view);}return null;}//绑定&＃64;Overridepublic void onBindViewHolder(&＃64;NonNull RecyclerView.ViewHolder holder, int position) {}//有多少个item&＃xff1f;&＃64;Overridepublic int getItemCount() {return list.size();}//item类型&＃64;Overridepublic int getItemViewType(int position) {return list.get(position).type;}//&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;以下为item中的button控件点击事件处理&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;//第一步&＃xff1a;自定义一个回调接口来实现Click和LongClick事件public interface OnItemClickListener {void onItemClick(View v, int position);void onItemLongClick(View v);}public OnItemClickListener mOnItemClickListener;//第二步&＃xff1a;声明自定义的接口//第三步&＃xff1a;定义方法并暴露给外面的调用者public void setOnItemClickListener(OnItemClickListener listener) {this.mOnItemClickListener &＃61; listener;}
//&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;&＃43;//第一个item类型class OneViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {private ImageView ivIcon;private TextView tvUsername, tvMessage;private Button btnAgree, btnRefuse;//private List list;public OneViewHolder(View itemView) {super(itemView);ivIcon &＃61; itemView.findViewById(R.id.iv_icon);tvUsername &＃61; itemView.findViewById(R.id.tv_username);tvMessage &＃61; itemView.findViewById(R.id.tv_message);btnAgree &＃61; itemView.findViewById(R.id.btn_agree);btnRefuse &＃61; itemView.findViewById(R.id.btn_refuse);// 为item及item内部控件添加点击事件itemView.setOnClickListener(this);btnAgree.setOnClickListener(this);btnRefuse.setOnClickListener(this);}&＃64;Overridepublic void onClick(View v) {if (mOnItemClickListener !&＃61; null) {mOnItemClickListener.onItemClick(v, getAdapterPosition());}}}//第二个item类型class TwoViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {private ImageView ivIcon;private TextView tvUsername;public TwoViewHolder(View itemView) {super(itemView);ivIcon &＃61; itemView.findViewById(R.id.iv_icon);tvUsername &＃61; itemView.findViewById(R.id.tv_username);// 为item添加点击事件itemView.setOnClickListener(this);}&＃64;Overridepublic void onClick(View v) {if (mOnItemClickListener !&＃61; null) {mOnItemClickListener.onItemClick(v, getAdapterPosition());}}}}

第六步&＃xff1a;在MainActivity中编写&＃xff0c;初始化数据&＃xff0c;设置适配器

package com.ied.recyclerview;import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.Toast;
import com.ied.recyclerview.adapter.MyRecyclerViewAdapter;
import com.ied.recyclerview.entity.Data;
import java.util.ArrayList;
import java.util.List;public class MainActivity extends AppCompatActivity {private RecyclerView rvRecyclerView;private MyRecyclerViewAdapter adapter;private List list;&＃64;Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initView();initData();rvRecyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));//控制布局为LinearLayout或者是GridView或者是瀑布流布局adapter &＃61; new MyRecyclerViewAdapter(list,this);rvRecyclerView.setAdapter(adapter);// 设置item及item中控件的点击事件adapter.setOnItemClickListener(MyItemClickListener);}private void initView() {rvRecyclerView &＃61; (RecyclerView) findViewById(R.id.rv_recyclerView);}private void initData() {list &＃61; new ArrayList<>();list.add(new Data(1,R.mipmap.ic_launcher, "username", "让我们成为好友吧&＃xff01;"));list.add(new Data(2,R.mipmap.ic_launcher, "username", "让我们成为好友吧&＃xff01;"));list.add(new Data(1,R.mipmap.ic_launcher, "username", "让我们成为好友吧&＃xff01;"));list.add(new Data(2,R.mipmap.ic_launcher, "username", "让我们成为好友吧&＃xff01;"));list.add(new Data(1,R.mipmap.ic_launcher, "username", "让我们成为好友吧&＃xff01;"));}/*** item&＃xff0b;item里的控件点击监听事件*/private MyRecyclerViewAdapter.OnItemClickListener MyItemClickListener &＃61; new MyRecyclerViewAdapter.OnItemClickListener() {&＃64;Overridepublic void onItemClick(View v, int position) {switch (v.getId()){case R.id.btn_agree:Toast.makeText(MainActivity.this,"你点击了同意按钮"&＃43;(position&＃43;1),Toast.LENGTH_SHORT).show();break;case R.id.btn_refuse:Toast.makeText(MainActivity.this,"你点击了拒绝按钮"&＃43;(position&＃43;1),Toast.LENGTH_SHORT).show();break;default:Toast.makeText(MainActivity.this,"你点击了item按钮"&＃43;(position&＃43;1),Toast.LENGTH_SHORT).show();break;}}&＃64;Overridepublic void onItemLongClick(View v) {}};}


最后成功实现多布局item及item内部控件的点击事件&＃xff01;&＃xff01;
